Installation

Red Hat CodeReady Studio comes with everything pre-bundled in its installer. Simply download it from our Red Hat CodeReady product page and run it like this:

java -jar codereadystudio-<installername>.jar

JBoss Tools or Bring-Your-Own-Eclipse (BYOE) CodeReady Studio require a bit more:

This release requires at least Eclipse 4.15 (2020-03) but we recommend using the latest Eclipse 4.15 2020-03 JEE Bundle since then you get most of the dependencies preinstalled.

Once you have installed Eclipse, you can either find us on the Eclipse Marketplace under "JBoss Tools" or "Red Hat CodeReady Studio".

For JBoss Tools, you can also use our update site directly.

http://download.jboss.org/jbosstools/photon/stable/updates/

What is new?

Our main focus for this release was a new tooling for the Quarkus framework, improvements for container based development and bug fixing. Eclipse 2020-03 itself has a lot of new cool stuff but let me highlight just a few updates in both Eclipse 2020-03 and JBoss Tools plugins that I think are worth mentioning.

OpenShift

OpenShift Container Platform 4.4 support

With the new OpenShift Container Platform (OCP) 4.4 now available, JBoss Tools is compatible with this major release in a transparent way. Just define your connection to your OCP 4.4 based cluster as you did before for an OCP 3 cluster, and use the tooling !

Quarkus

Language support for Kubernetes, Openshift, S2i and Docker properties

There is now completion, hover, documentation and validation for kubernetes., openshift., s2i., docker. properties

quarkus20

Enter kubernetes prefix:

quarkus21

Enter openshift prefix:

quarkus22

Enter s2i prefix:

quarkus23

Language support for MicroProfile REST Client properties

Likewise, there is now completion, hover, documentation and validation for the MicroProfile properties from REST Client.

After registering a REST client using @RegisterRestClient like so:

package org.acme;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;

import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;

@RegisterRestClient
public interface MyServiceClient {
	@GET
    @Path("/greet")
    Response greet();
}

The related MicroProfile Rest config properties will have language feature support (completion, hover, validation, etc.).

quarkus24

Change the Java code so that the configuration key is changed:

package org.acme;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;

import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;

@RegisterRestClient(configKey = "myclient")
public interface MyServiceClient {
	@GET
    @Path("/greet")
    Response greet();
}

and notice the code assist is changed accordingly:

quarkus25

Language support for MicroProfile Health

Likewise, there is now completion, hover, documentation and validation for the MicroProfile Health artifacts.

So if you have the following Health class:

package org.acme;

import org.eclipse.microprofile.health.Health;

@Health
public class MyHealth {

}

you will get a validation error (as the class does not implement the HealthCheck interface:

quarkus26

Similarly, if you have a class that implements HealthCheck but is not annotated with Health, some workflow applies:

package org.acme;

import org.eclipse.microprofile.health.HealthCheck;
import org.eclipse.microprofile.health.HealthCheckResponse;

public class MyHealth implements HealthCheck {

	@Override
	public HealthCheckResponse call() {
		// TODO Auto-generated method stub
		return null;
	}

}

you will get a validation message (as the class is not annotated with Health interface):

quarkus27

As there are several ways to fix the problem, then several quick fixes are proposed.

Better extensions reporting in the Quarkus project wizard

With the Quarkus extensions ecosystem growing, we improved information about extensions in the Quarkus project wizard.

When you select an extension in the wizard, you will see the extension description in the lower side of the wizard. If the extension has a guide on the Quarkus web site, a link will also be displayed and clicking on that link will open the guide on your local web browser.

Hibernate Tools

Hibernate Runtime Provider Updates

A number of additions and updates have been performed on the available Hibernate runtime providers.

Runtime Provider Updates

The Hibernate 5.4 runtime provider now incorporates Hibernate Core version 5.4.14.Final and Hibernate Tools version 5.4.14.Final.

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.16.Final and Hibernate Tools version 5.3.16.Final.

Platform

Views, Dialogs and Toolbar

Hierarchical project layout by default in Project Explorer

To better handle multi-module, nested and hierarchical projects, the default project layout in Project Explorer view has been changed from Flat to Hierarchical.

You can restore the layout to Flat using the view menu (⋮).

Debug

Console View now interprets form feed and vertical tab characters

The interpretation of ASCII control characters in the Console View was extended to recognize the characters: \f - form feed and \v - vertical tab (in languages that support it).

This feature is disabled by default. You can enable it on the Run/Debug > Console preference page.

formfeed
Termination time in Console View

The Console View label will now show the termination time of a process in addition to the launch time.

process termination time

Preferences

Preference to select resource rename mode

A preference has been added in the General preferences page, that allows you to select the resource renaming mode in the Project Explorer: either open an inlined text field or a dialog. By default, the inline rename mode is selected.

The preference can also be specified via product customization:

  • org.eclipse.ui.workbench/RESOURCE_RENAME_MODE=inline

  • org.eclipse.ui.workbench/RESOURCE_RENAME_MODE=dialog

Rename that would affect more than 1 resource is always performed with a dialog.
resource rename mode preference

Themes and Styling

Welcome screen in dark theme

When Eclipse is in dark theme, the welcome screen also appears dark on macOS and Linux.

dark welcome

General Updates

Interactive performance

Interactive performance has been further improved in this release.

Redraw is turned off by default during collapse and expand operations in tree viewer

To improve interactive performance, redraw is turned off by default during the collapse and expand operation of tree viewers. This significantly improves these operations compared to drawing the updates synchronously.

Java Developement Tools (JDT)

Java 14 Support

Java 14

Java™ 14 is available and Eclipse JDT supports Java 14 for the Eclipse 4.15 release.

The release notably includes the following Java 14 features:

  • JEP 361: Switch Expressions (Standard).

  • JEP 359: Records (Preview).

  • JEP 368: Text Blocks (Second Preview).

  • JEP 305: Pattern Matching for Instanceof (Preview).

Please note that preview option should be on for preview language features. For an informal introduction of the support, please refer to Java 14 Examples wiki.

Java Editor

Subword code completion

Content Assist now supports subword patterns, similar to Eclipse Code Recommenders and other IDEs. For example, completing on addmouselistener proposes results like addMouseMoveListener and addMouseWheelListener.

subword code completion

This feature can be enabled using the Show subword matches option on the Java > Editor > Content Assist preference page.

Subtype code completion

Content Assist will prioritize displaying constructor completions whose declaring type inherits from the expected return type within the completion context.

For example, completing on :

Queue<String> queue = new L

prioritizes constructors for LinkedBlockingQueue, LinkedBlockingDeQueue and LinkedList.

subtype code completion
Option for non-blocking Java completion

Code completion in the Java editor can now be run in a separate non-UI thread to prevent UI freezes in case of long computations. To enable this non-blocking computation, go to Preferences > Java > Editor > Content Assist > Advanced and check Do not block UI Thread while computing completion proposals preference. This option is currently disabled by default.

Non-blocking completion is useful when completion proposals are long to compute, as it allows you to type or use other parts of the IDE in the meantime.

Some completion participants may prevent this option from being effective (typically if the Java completion extension doesn’t declare requiresUIThread="false"), so the UI thread may still be used even if this option is set.

Quick fix to wrap Optional statements

A quick fix has been added to wrap an Optional statement.

The options for a primitive statement are: Optional.empty() and Optional.of(). Type statements also have Optional.ofNullable().

Example for type objects:

wrapOptional1

Selecting Wrap with nullable Optional for type object results in:

wrapOptional4

Example for primitive:

wrapOptional2

Selecting Wrap with Optional for primitive results in:

wrapOptional3
Simplify functional interface instances

A new clean up has been added that simplifies the lambda expression and the method reference syntax and is enabled only for Java 8 and higher.

The clean up removes parenthesis for a single untyped parameter, return statement for a single expression and brackets for a single statement. It replaces a lambda expression by a creation or a method reference when possible.

To select the clean up, invoke Source > Clean Up…​, use a custom profile, and on the Configure…​ dialog select Simplify lambda expression and method reference syntax on the Code Style tab.

lambda expression enhancements

For the given code:

lambda expression enhancements before

You get this after the clean up:

lambda expression enhancements after
Directly use Map method

Some map manipulations are unnecessarily verbose. The new cleanup option Operate on Maps directly calls methods on a map instead of calling the same methods on the key set or the values.

Beware! If you create Map implementations that don’t follow the Map specification, this cleanup may break the behavior (a size() method that changes the values, an iterator that destroys the items…​).

map method preferences

For the given code:

map method before

You get this after the clean up:

map method after
Uppercase for long literal suffix

A new cleanup option Use uppercase for long literal suffix has been added. It will rewrite long literals like 101l with an uppercase L like 101L to avoid ambiguity.

uppercase literal suffix
Surround with "try-with-resources" block

Corresponding to the quick fix which will surround a selection with a "try-with-resources" block, a new action has been added to the Surround With menu.

For example, selecting the lines as shown:

surroundwithresources1

and right-clicking and selecting Surround With → Try-with-resources Block

surroundwithresources

results in:

surroundwithresources2
Quick fixes for module-info Javadoc

Quick fixes have been added to fix the missing and duplicate @provides and @uses Javadoc tags in a module-info file.

modulequickfix
No more spurious semicolon from import completion

Almost 18 years ago, it was reported that completion for imports adds an unnecessary semicolon if one already exists (like when changing an existing import). Now this extra semicolon is no longer inserted.

Java Compiler

Warn when legacy code can taint null-checked values

When using null-annotations for advanced null analysis, it is inherently tricky to combine your code with "legacy" code that has no null annotations and has not been blessed by such analysis.

Previously, Eclipse would only warn you when you obtain a dubious value from a legacy API, but it would keep silent in the opposite case: passing a value of an annotated type into legacy API. Still in specific situations this can cause a NullPointerException to be thrown in your null-checked code:

null into nonnull list

The console shows an exception thrown from within your checked main method (see the class-level @NonNullByDefault). It also shows the new warning, which Eclipse raises to alert you of this danger.

Hint: The shown code assumes the list names to have type List<@NonNull String>, but the legacy method Legacy.printNames() succeeds to taint this list by inserting a null element. This goes unnoticed because that method views the list has having type List<String>, with no nullness constraint on the type argument.

By default this problem is raised at level info, but the severity can be configured in the compiler settings:

configure null vs legacy problem
Improved Resource leak analysis

Resource leak analysis has been improved in several ways.

Most importantly, the analysis now consistently considers resources (=values of type AutoCloseable) which are acquired using a method call, where previously under some circumstances resource allocation got unnoticed if it was wrapped in a factory method, like in the following example:

makePrintWriter("/tmp/log.txt").printf("%d", 42);
// a PrintWriter is never closed!

Second, resource leak analysis now leverages knowledge about well-known resource classes that support fluent programming, i.e., instance methods which return this to enable chains of method calls. Where a naive analysis could consider the method result as a new resource coming into scope, special knowledge about these classes informs the analysis that it is one and the same resource. This concerns the following system classes:

from java.io

CharArrayWriter, Console, PrintStream, PrintWriter, StringWriter, Writer

from java.nio.channels

AsynchronousFileChannel, AsynchronousServerSocketChannel, FileChannel, NetworkChannel, SeekableByteChannel, SelectableChannel, Selector, ServerSocketChannel

from java.util

Formatter

The following example is now understood to be safe, because analysis understands that the resource returned by append() is the same as the initial pw:

PrintWriter pw = new PrintWriter("/tmp/log.txt");
pw.printf("%d", 42).append(" is the answer").close();

Generally, resource leak analysis was made more precise regarding several specific situations.

Java Formatter

Java formatter application requires a workspace

The Java formatter application will provide a sensible error message if a workspace is required but not provided (-data command line option). This also enables the -help option to be run on the formatter without a workspace specified.

A new bundle services the org.eclipse.jdt.core.JavaCodeFormatter application. This new bundle is part of the JDT feature. Users who are not using the JDT feature to define their set of bundles will need to add org.eclipse.jdt.core.formatterapp to their set of bundles.

Debug

Functional debug expressions

Lambda expressions and method references are now supported in debug expressions, such as in the Expressions view and in breakpoint condition expressions.

debug functional expressions

JDT Developers

New bundle org.eclipse.jdt.core.formatterapp

The entry point of the org.eclipse.jdt.core.JavaCodeFormatter application has been moved to a new bundle, org.eclipse.jdt.core.formatterapp.

And more…​

Language support for MicroProfile REST Client properties

Likewise, there is now completion, hover, documentation and validation for the MicroProfile properties from REST Client.

After registering a REST client using @RegisterRestClient like so:

package org.acme;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;

import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;

@RegisterRestClient
public interface MyServiceClient {
	@GET
    @Path("/greet")
    Response greet();
}

The related MicroProfile Rest config properties will have language feature support (completion, hover, validation, etc.).

import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;

@RegisterRestClient(configKey = "myclient")
public interface MyServiceClient {
	@GET
    @Path("/greet")
    Response greet();
}

and notice the code assist is changed accordingly:

quarkus25

Language support for MicroProfile Health

Likewise, there is now completion, hover, documentation and validation for the MicroProfile Health artifacts.

So if you have the following Health class:

package org.acme;

import org.eclipse.microprofile.health.Health;

@Health
public class MyHealth {

}

you will get a validation error (as the class does not implement the HealthCheck interface:

Similarly, if you have a class that implements HealthCheck but is not annotated with Health, some workflow applies:

package org.acme;

import org.eclipse.microprofile.health.HealthCheck;
import org.eclipse.microprofile.health.HealthCheckResponse;

public class MyHealth implements HealthCheck {

	@Override
	public HealthCheckResponse call() {
		// TODO Auto-generated method stub
		return null;
	}

}

you will get a validation error (as the class is not annotated with Health interface:

quarkus27

As there are several ways to fix the problem, then several quick fixes are proposed.

Server Tools

Wildfly 19 Server Adapter

A server adapter has been added to work with Wildfly 19. It adds support for Java EE 8, Jakarta EE 8 and Microprofile 3.3.

Please note that while creating a Wildfly 19 server adapter, you may get a warning. This is going to be fixed for the release.

JBoss Tools 4.14.0 and Red Hat CodeReady Studio 12.14 for Eclipse 2019-12 are here waiting for you. Check it out!

crstudio12

Installation

Red Hat CodeReady Studio comes with everything pre-bundled in its installer. Simply download it from our Red Hat CodeReady product page and run it like this:

java -jar codereadystudio-<installername>.jar

JBoss Tools or Bring-Your-Own-Eclipse (BYOE) CodeReady Studio require a bit more:

This release requires at least Eclipse 4.14 (2019-12) but we recommend using the latest Eclipse 4.14 2019-12 JEE Bundle since then you get most of the dependencies preinstalled.

Once you have installed Eclipse, you can either find us on the Eclipse Marketplace under "JBoss Tools" or "Red Hat CodeReady Studio".

For JBoss Tools, you can also use our update site directly.

http://download.jboss.org/jbosstools/photon/stable/updates/

What is new?

Our main focus for this release was a new tooling for the Quarkus framework, improvements for container based development and bug fixing. Eclipse 2019-12 itself has a lot of new cool stuff but let me highlight just a few updates in both Eclipse 2019-12 and JBoss Tools plugins that I think are worth mentioning.

OpenShift

OpenShift Container Platform 4.3 support

With the new OpenShift Container Platform (OCP) 4.3 now available (see this article), JBoss Tools is compatible with this major release in a transparent way. Just define your connection to your OCP 4.3 based cluster as you did before for an OCP 3 cluster, and use the tooling !

New OpenShift Application Explorer view

A new OpenShift Application Explorer window has been added in addition to the OpenShift Explorer. It is based on OpenShift Do. It provides a different and simplified user experience allowing easy and rapid feedback through inner loop and debugging.

Let’s see it in action.

Opening the OpenShift Application Explorer view

If you opened a brand new workspace, you should see the OpenShift Application Explorer view in the list of views available on the botton part of the screen:

application explorer

If you don’t see the view being listed, you can open it through the Window -→ Show View -→ Other menu, enter open in the filter text box and then select OpenShift Application Explorer:

application explorer1
application explorer2

Expanding the root node will display the list of projects available on the cluster:

application explorer3
Java based micro service

We will show how to deploy a Java based microservice and how to use the various features. But we first need to load the component source code in our workspace. Thanks to the launcher wizard, we can do that easilly. Try Ctrl+N and select the Launcher project wizard:

application explorer4

Then click the Next button:

Select rest-http in the Mission field, vert.x community in the Runtime field, myservice in the Project name field:

application explorer5

Then click the Finish button: a new project will be added to your workspace. Once the dependencies resolution has been completed, we’re ready to start playing with the cluster.

Create the component

Now that we have the source code, we can create the component. From the OpenShift Application Explorer view, right select the project (myproject), and the click the New → Component menu:

application explorer6

Enter myservice in the Name field, click the Browse button to select the project we have just created, select java in the Component type field, select 8 in the Component version field, enter myapp in the Application field and uncheck the Push after create check-box:

application explorer7

Then click the Finish button. The component will be created and expanding the project node will now show the application that contains our component:

application explorer8

Expanding the application will now display our component:

application explorer9

The component has been created but it is not yet deployed on the cluster (as we unchecked the Push after create check-box. In order to deploy it,right select the component and click the Push menu. The deployment will be created and then a build will be launched. A new window will be created in the Console view. After a while, you should see the following output:

application explorer10

The component is now deployed to the cluster but we cannot access it as we need to define an URL to access it externally. Right select the component and click the New → URL menu:

application explorer11

Enter url1 in the Name field and select 8080 in the Port field:

application explorer12

Then click on the Finish button. The URL is created but not on the cluster, so we need to push again the component so that the local configuration is synchronized with the configuration on the cluster. The Console window will display a message claiming that a push is now required:

application explorer13

So push the component again (component → Push).

Let’s check that we can now access the service. Expand the component level so that we can see the URL we have just created:

application explorer14

Right select the URL and click the Open in Browser menu, you should see the new browser window:

application explorer15

You can test the service: enter demo in the text box and click the Invoke button:

application explorer16
Feedback loop

We will now see how we can get fast feedback on code changes. So let’s modify the application code and see how we can synchronize the changes to the cluster.

In the Project Explorer view, locate the HttpApplication.java file:

application explorer17

Double click on the file to open the editor:

application explorer18

On line 14, change the line:

  protected static final String template = "Hello, %s!";

to

  protected static final String template = "Hello, %s!, we modified the code";

and press the Ctrl+S key in order to save the file.

For the OpenShift Application Explorer, right click the component (myservice) and click the Push menu to send the changes to the cluster: the component will be built again on the cluster with the next changes and after a few seconds, it will be available again:

application explorer19

Select the browser window again, enter demo1 in the textbox (we need to change the value we used before in order to make sure cache is not involved) and click the Invoke button again:

application explorer20

We’ve seen that, through a sequence of code modification(s) followed by a synchronize action (push) to the cluster, we can get a very fast feedback. If you don’t want to manually synchronize the the cluster (push), you can opt to automatically synchronize to the cluster with the Watch action: each time a code modification is done locally on your workstation, a new build will be automatically launched on the cluster.

Going further: debug your application on the cluster

Testing an application through code changes is a great achievement so far but it may be difficult for complex applications where we need to understand how the code behaves without the need to use the UI. That’s why the next step is to be able to debug our application live on the cluster.

The new OpenShift Application Explorer allow such a scenario. We will first set up a breakpoint in our application code. Select again the HttpApplication.java file and scroll down to the greeting method:

application explorer21

On line 41, double click in the left ruler column so that a breakpoint is set:

application explorer22

We are now ready to debug our application. In order to do that, we need to launch a local (Java in our case) debugger that will be connected to our application on the cluster. This is what the Debug action is doing: right select the component (myservice) and click the Debug menu: you will see that port forwarding has been started so that our local (Java) debugger can connect to the remote Java virtual machine:

application explorer23

and then a local (Java) debugger is launched and connected to that port. Let’s check now that we can debug our application:

Select the browser window again, enter demo2 in the textbox (we need to change the value we used before in order to make sure cache is not involved) and click the Invoke button again: as our breakpoint is hit, you will be asked if you want to switch to the Debug perspective (this may not be displayed if you previously selected the Remember my decision checkbox:

application explorer24

Click the Switch button and you will see the Debug perspective:

application explorer25

You are now debugging a Java component running on a remote cluster just like it was running locally on your workstation. Please note that we demoed this feature using a Java based component but we also support the same feature to NodeJS based components.

Quarkus

Starting with this release, we’ve added a new Quarkus tooling for applications built on top of the Supersonic Subatomic Java Quarkus framework.

Quarkus project creation wizard

A new wizard has been added to create a new Quarkus application project in your workspace. In order to launch it, first enter Ctrl+N to get the list of available wizards

quarkus1

In the filter text box, enter the qu characters to filter the list of wizards:

quarkus2

Select the Quarkus Project wizard and click the Next button:

quarkus3

The Project type combo allows you to choose between Maven or Gradle tool used to manage your project. We’ll go with Maven for this tutorial.

Enter a project name (we will use code-with-quarkus) and click the Next button:

quarkus4

This dialog allows you to choose various parameters for you project, like the project coordinates (group id, artifact id and version) along with the base REST endpoint information. We’ll use the default so click on the Next button:

quarkus5

This dialog allows to select which Quarkus extensions you want to add to your project. The extensions are grouped by categories, so first select a specific category in the left table. We will choose the Web one:

quarkus6 1

You should have noticed that the middle table has been updated. In order to add an extension, double click on the extension in the middle table. We will add RESTEasy JAX-RS and RESTEasy Qute (a templating engine):

quarkus7 1

You should have noticed that the extensions that you double clicked on are now being added to the right table. If you want to remove an extension from the list of selected ones, double click again either in the center table or in the right table.

We are now all set so click on the Finish button to launch the project creation. The project creation job is then launched, dependencies are being retrieved and after a while, the new project will appear in the Project Explorer window:

quarkus8

We have successfully created our first Quarkus project. Let’s see now how we can launch this application and debug it.

Running the Quarkus application

Running a Quarkus application can be done from the workbench Run configurations. Select the Run → Run Configurations…​ menu to display the dialog allowing to create a Run configuration.

quarkus9

Scroll down until the Quarkus Application is visible and select it:

quarkus10 1

Click on the New configuration button (top left):

quarkus11 1

A workspace project needs to be associated with the configuration so click on the Browse button to see the project selection dialog:

quarkus12 1

As the workspace contains a single project, it is automatically selected and we can click on the OK button:

quarkus13 1

The configuration is now ready to be used. So let’s start our Quarkus application by clicking on the Run button:

You should see a new Console being displayed.

quarkus14

The application is being built and after a while, it will be started:

quarkus15

Debugging the Quarkus application

Debugging a Quarkus application is just a simple as launching the previous configuration we’ve just created in Debug. You just need to open the Run → Debug Configurations…​. menu and click on the Debug button.

It will start the Quarkus application like in the previous paragraph but also connect a remote JVM debug configuration to your running Quarkus application. So if you have set breakpoints in your application source files, the execution will automatically stops there.

application.properties content assist

Every Quarkus application is configured through a configuration called application.properties.

The content of this configuration file is dependent of the set of Quarkus extensions that your application is using. Some settings are mandatory, some others are not and the possible values are specific to the nature of the setting: boolean, integer, limited set of values (enumerations).

So, as a developer, you need to look at various guides and documentations (the core Quarkus and the extension specific ones)

So Quarkus Tools provides content assist on those specific files that:

  • validates the content of the application.properties files

  • provides you with the possible setting names and values

Let’s see it in action.

Go to src/main/resources/application.properties in the project and right click and select Open With → Generic Text Editor:

quarkus16

Go the third line of the file and invoke code completion (Ctrl + Space):

quarkus17

For each setting, a documentation is displayed when you mouse over the setting. Let try to add quarkus.http.port to the file and mouse over this name:

quarkus18

If we enter a wrong value (false instead of a numeric value), then the error will be highlighted:

quarkus19

This is the first set of features that will be integration into the next version of JBoss Tools. We encourage you to used it and if you are missing features and/or enhancements, don’t hesitate to report them here: JBoss Tools issue tracker

Hibernate Tools

Hibernate Runtime Provider Updates

A number of additions and updates have been performed on the available Hibernate runtime providers.

Runtime Provider Updates

The Hibernate 5.4 runtime provider now incorporates Hibernate Core version 5.4.12.Final and Hibernate Tools version 5.4.12.Final.

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.15.Final and Hibernate Tools version 5.3.15.Final.

Deprecation

The Forge, Java Server Tools (JST) and Visual Page Editor (VPE) have been deprecated. Even though they received an update with this release, we have no plan to maintain or add new features and they may be removed in the future.

In addition, the adapters for Red Hat JBoss Enterprise Application Server 4.3 and 5.0 have also been deprecated.

Platform

Views, Dialogs and Toolbar

New view menu icon

The view menu chevron icon (▽) is replaced by a modern equivalent, the vertical ellipsis ( ⠇).

Almost every view has a menu that may contain additional configuration settings like filters, layout settings, and so on. The view menu was often overlooked and we expect that this change will help users to find it.

view menu
Find Actions: The improved Quick Access

The formerly called Quick Access action has been retitled to Find Actions to better emphasize its goal.

The related UI has changed a bit to improve its usage and accessibility:

  • The widget item is now a regular toolbar item (button-like)

  • An icon is shown

  • Right-clicking on the tool item works and shows typical actions, including Hide

  • The proposals are now a regular dialog, centered on the workbench

These changes will greatly improve the experience if you’re using a screen reader as it relies on a more standardized focus state. This also leverages all the default and usual accessibility features of dialogs (moveable, resizable…​).

Loading the proposals has been improved as well to avoid UI freezes when loading proposals.

Find Actions finds text in file contents

Find Actions is now extended by the Quick Text Search feature to show the potential text matches in file contents also in the proposals.

file content find action

If the Quick Text Search bundle wasn’t started yet, you may miss those matches. In this case, you can use Find Actions itself to activate the Quick Text Search by finding and selecting the Activate bundle for 'File content' proposals entry.

activate file content
Find Actions lists workspace files

Find Actions can now list matching file names from the workspace (similar to the Open Resource dialog). Upon selection the file is opened in the editor.

find actions resources
Inline rename for simple resources while in Project Explorer.

In the Project Explorer, renaming (with the F2 shortcut or Rename context menu) will start an inline rename for normal resources when other files aren’t affected by the rename.

project explorer inline renaming

In cases where other files are affected by the rename, or the rename operation is customized, the rename dialog will appear as it previously did.

Text Editors

Show problem markers inline

You can now see the errors, warnings, and info markers inline in most of the text editors. No more mousing around to see the actual error message!

annotation code mining jdt

You can see the available quick fixes by clicking on the message.

annotation code mining quickfix

You can enable it on the General > Editors > Text Editors preference page and set Show Code Minings for Annotations to:

  • None (default)

  • Errors only

  • Errors and Warnings

  • Errors, Warnings and Info

Backspace/delete can treat spaces as tabs

If you use the Insert spaces for tabs option, now you can also change the backspace and delete keys behavior to remove multiple spaces at once, as if they were a tab.

The new setting is called Remove multiple spaces on backspace/delete and is found on the General > Editors > Text Editors preference page.

delete spaces as tabs

Debug

Collapse All Button in the Debug View

In the Debug View, now you can now use the new Collapse All button to collapse all the launches.

Before collapsing:

collapse all debug view before

After collapsing:

collapse all debug view after
Control character interpretation in Console View

The Console View can now interpret the control characters backslash (\b) and carriage return (\r).

This feature is disabled by default. You can enable it on the Run/Debug > Console preference page.

animated progress in console

Themes and Styling

Improvements in UI Forms Styling

CSS customization of ExpandableComposite and Section was reworked to give you more control over their styling. In dark mode, those elements now integrate better with other Form elements.

Old:

pom dark old

New:

pom dark new
Perspective switcher gets aligned with normal toolbar styling

The special styling of the Perspective switcher has been removed to make the Toolbar look consistent. This also reduces OS specific styling issues with the perspective switcher.

Old:

old perspective switcher

New:

new perspective switcher
Usage of consistent colors for the dark theme

The usage of different shades of gray in the dark theme was reduced.

The styling of the widgets is also not based on the selected view anymore, which makes the UI more consistent.

General Updates

Ant 1.10.7

Eclipse has adopted Ant version 1.10.7.

Support for the Ant include task added

The Ant include task (available in the Ant library since 1.8.0) is now fully recognized by the ant-ui-plugin and validated accordingly.

Java Developement Tools (JDT)

Java 13 Support

Java 13

Java™ 13 is available and Eclipse JDT supports Java 13 for the Eclipse 4.14 release.

The release notably includes the following Java 13 features:

  • JEP 354: Switch Expressions (Preview).

  • JEP 355: Text Blocks (Preview).

Please note that these are preview language feature and hence enable preview option should be on. For an informal introduction of the support, please refer to Java 13 Examples wiki.

Keyboard shortcut for Text Block creation

A keyboard shortcut Ctrl + Shift + ' is added in the Java Editor for text blocks, which is a preview feature added in Java 13.

Conditions under which this keyboard shortcut works are:

  • The Java Project should have a compliance of 13 or above and the preview features should be enabled.

  • The selection in the editor should not be part of a string or a comment or a text block.

Examples:

textblock pre creation1

Pressing the shortcut gives:

textblock post creation1

You can also encompass a selected text in text block as below:

textblock pre creation2

On pressing the shortcut, you get this:

textblock post creation2

Java Editor

Remove unnecessary array creation

A new cleanup action Remove unnecessary array creation has been added. It will remove explicit array creation for varargs parameters.

unnecessary array creation option

For the given code:

unnecessary array creation before

After cleanup, you get this:

unnecessary array creation after
Push negation down in expression

A new Java cleanup/save action Push down negation has been added. It reduces the double negation by reverting the arithmetic expressions.

For instance:

!!isValid; becomes isValid;

!(a != b); becomes (a == b);

push down negation
Provide templates for empty Java source files

When dealing with empty Java source files, some basic templates (class, interface, enum) will now be available from the content assist popup.

templates empty java file
Postfix completion proposal category

Postfix completion allows certain kinds of language constructs to be applied to the previously entered text.

For example: Entering "input text".var and selecting the var - Creates a new variable proposal, will result in String name = "input text".

postfix completion
try-with-resources quickfix

A quickfix has been added to create a try-with-resources statement based on the selected lines. Lines that are selected must start with declarations of objects that implement AutoCloseable. These declarations are added as the resources of the try-with-resources statement.

If there are selected statements that are not eligible resources (such as Objects that don’t implement AutoCloseable), then the first such statement and all the following selected statements will be placed in the try-with-resources body.

Method before applying try-with-resources:

tryWithResource1

Select all the lines inside the method, then use the short-cut Ctrl+1 and click on Surround with try-with-resources from the list:

tryWithResource2

This results in:

tryWithResource3
Javadoc tag checking for modules

Support has been added to check the Javadoc of a module-info.java file to report missing and duplicate @uses and @provides tags depending on the compiler settings (Preferences > Java > Compiler > Javadoc).

checkModuleJavadoc

Java Formatter

Formatting of text blocks

The code formatter can now handle text blocks, which is a preview feature added in Java 13. It’s controlled by the Text block indentation setting, found right in the Indentation section of the Profile Editor (Preferences > Java > Code Style > Formatter > Edit…​).

By default, text block lines are indented the same way as wrapped code lines, that is with two extra tabs relative to the starting indentation (or whatever is set as Default indentation for wrapped lines in the Line Wrapping section). You can also set it to use only one tab for indentation (Indent by one), align all lines to the position of the opening quotes (Indent on column), or preserve the original formatting (Do not touch).

formatter text block
Blank lines between Javadoc tags

The code formatter can now divide Javadoc tags into groups (by type, for example @param, @throws, @returns) and separate these groups with blank lines. This feature can be turned on in the Comments > Javadocs section by checking the Blank lines between tags of different type box.

Space after not operator

A new setting has been added to control whether a space should be added after not (!) operator, independently from other unary operators. To find it, expand sections Whitespace > Expressions > Unary operators and go to the last checkbox.

formatter space after not

JUnit

BREE update for org.eclipse.jdt.junit.runtime

The Bundle Required Execution Environment (BREE) for the org.eclipse.jdt.junit.runtime bundle is now J2SE-1.5.

Debug

No suspending on exception recurrence

A new workspace preference has been added for exception breakpoints: Suspend policy for recurring exception instances controls whether the same exception instance may cause the debugger to suspend more than once.

preference exception recurrence

This option is relevant when debugging an application that has try blocks at several levels of the architecture. In this situation an exception breakpoint may fire multiple times for the same actual exception instance: A throw statement inside a catch block may re-throw the same exception. The same holds for each finally block or try-with-resources block.

When the debugger stops due to an exception breakpoint, you may want to continue your debug session by pressing Resume (F8), but all that catching and re-throwing will force you to observe all locations where the same exception will surface again and again. Suspending at all try blocks on the call stack may also spoil your context of open Java editors, by opening more editors of classes that are likely irrelevant for the debugging task at hand.

The JDT Debugger will now detect this situation, and the first time it notices the same exception instance recurring at the surface, a new question dialog is shown:

dialog exception recurrence

If you select Skip in this dialog, the current exception instance will be dismissed for good. Still, new instances of the same exception type will cause suspending when they are thrown.

If you check Remember my decision your choice will be stored in the mentioned workspace preference to be effective for all exception breakpoints.

Even after choosing Skip — resp. Only once in the preferences — you can have the old behavior simply by pressing Step Return (F7) instead of Resume.

JDT Developers

Flag whether content assist extension needs to run in UI thread

The existing org.eclipse.jdt.ui.javaCompletionProposalComputer, org.eclipse.jdt.ui.javadocCompletionProposalComputer and org.eclipse.jdt.ui.javaCompletionProposalSorters extension points now allow a new attribute requiresUIThread that allows a developer to declare whether running in the UI thread is required or not.

This information will be used by the Content Assist operation to allow some optimizations and prevent UI freezes by reducing the amount of work happening in the UI thread.

To preserve backward compatibility, the default value for this attribute (if unset) is true, meaning the extension is expected to run in the UI thread.

And more…​

You can find more noteworthy updates in on this page.

What is next?

Having JBoss Tools 4.14.0 and Red Hat CodeReady Studio 12.14 out we are already working on the next release for Eclipse 2020-03.

Enjoy!

Jeff Maury

Happy to announce 4.14.0.AM1 (Developer Milestone 1) build for Eclipse 2019-12.

Downloads available at JBoss Tools 4.14.0 AM1.

What is New?

Full info is at this page. Some highlights are below.

Quarkus Tools

Quarkus Tools added to JBoss Tools

A new component has been added to JBoss Tools. Quarkus Tools. It aims at providing tools for Quarkus applications developers. The initial set of features is:

  • Wizard for creating Quarkus projects based on code.quarkus.io

  • Code completion and syntax validation on application.properties

  • Launching your Quarkus application in Run/Debug mode

Quarkus project creation wizard

A new wizard has been added to create a new Quarkus application project in your workspace. In order to launch it, first enter Ctrl+N to get the list of available wizards

quarkus1

In the filter text box, enter the qu characters to filter the list of wizards:

quarkus2

Select the Quarkus Project wizard and click the Next button:

quarkus3

The Project type combo allows you to choose between Maven or Gradle tool used to manage your project. We’ll go with Maven for this tutorial.

Enter a project name (we will use code-with-quarkus) and click the Next button:

quarkus4

This dialog allows you to choose various parameters for you project, like the project coordinates (group id, artifact id and version) along with the base REST endpoint information. We’ll use the default so click on the Next button:

quarkus5

This dialog allows to select which Quarkus extensions you want to add to your project. The extensions are grouped by categories, so first select a specific category in the left table. We will choose the Web one:

quarkus6

You should have noticed that the middle table has been updated. In order to add an extension, double click on the extension in the middle table. We will add RESTEasy JAX-RS and RESTEasy Qute (a templating engine):

quarkus7

You should have noticed that the extensions that you double clicked on are now being added to the right table. If you want to remove an extension from the list of selected ones, double click again either in the center table or in the right table.

We are now all set so click on the Finish button to launch the project creation. The project creation job is then launched, dependencies are being retrieved and after a while, the new project will appear in the Project Explorer window:

quarkus8

We have successfully created our first Quarkus project. Let’s see now how we can launch this application and debug it.

Running the Quarkus application

Running a Quarkus application can be done from the workbench Run configurations. Select the Run → Run Configurations…​ menu to display the dialog allowing to create a Run configuration.

quarkus9

Scrool down until the Quarkus Launch Configuration is visible and select it:

quarkus10

Click on the New configuration button (top left):

quarkus11

A workspace project needs to be associated with the configuration so click on the Browse button to see the project selection dialog:

quarkus12

As the workspace contains a single project, it is automatically selected and we can click on the OK button:

quarkus13

The configuration is not ready to be used. So let’s start our Quarkus application by clicking on the Run button:

You should see a new Console being displayed.

quarkus14

The application is being built and after a while, it will be started:

quarkus15
Debugging the Quarkus application

Debugging a Quarkus application is just a simple as launching the previous configuration we’ve just created in Debug. You just need to open the Run → Debug Configurations…​. menu and click on the Debug button.

It will start the Quarkus application like in the previous paragraph but also connect a remote JVM debug configuration to your running Quarkus application. So if you have set breakpoints in your application source files, the execution will automatically stops there.

application.properties content assist

Every Quarkus application is configured through a configuration called application.properties.

The content of this configuration file is dependent of the set of Quarkus extensions that your application is using. Some settings are mandatory, some others are not and the possible values are specific to the nature of the setting: boolean, integer, limited set of values (enumerations).

So, as a developer, you need to look at various guides and documentations (the core Quarkus and the extension specific ones)

So Quarkus Tools provides content assist on those specific files that:

  • validates the content of the application.properties files

  • provides you with the possible setting names and values

Let’s see it in action.

Go to src/main/resources/application.properties in the project and right click and select Open With → Generic Text Editor:

quarkus16

Go the third line of the file and invoke code completion (Ctrl + Space):

quarkus17

For each setting, a documentation is displayed when you mouse over the setting. Let try to add quarkus.http.port to the file and mouse over this name:

quarkus18

If we enter a wrong value (false instead of a numeric value), then the error will be highlighted:

quarkus19

This is the first set of features that will be integration into the next version of JBoss Tools. We encourage you to used it and if you are missing features and/or enhancements, don’t hesitate to report them here: JBoss Tools issue tracker

Enjoy!

Jeff Maury

JBoss Tools 4.13.0 and Red Hat CodeReady Studio 12.13 for Eclipse 2019-09 are here waiting for you. Check it out!

crstudio12

Installation

Red Hat CodeReady Studio comes with everything pre-bundled in its installer. Simply download it from our Red Hat CodeReady product page and run it like this:

java -jar codereadystudio-<installername>.jar

JBoss Tools or Bring-Your-Own-Eclipse (BYOE) CodeReady Studio require a bit more:

This release requires at least Eclipse 4.13 (2019-09) but we recommend using the latest Eclipse 4.13 2019-09 JEE Bundle since then you get most of the dependencies preinstalled.

Once you have installed Eclipse, you can either find us on the Eclipse Marketplace under "JBoss Tools" or "Red Hat CodeReady Studio".

For JBoss Tools, you can also use our update site directly.

http://download.jboss.org/jbosstools/photon/stable/updates/

What is new?

Our main focus for this release was improvements for container based development and bug fixing. Eclipse 2019-09 itself has a lot of new cool stuff but let me highlight just a few updates in both Eclipse 2019-09 and JBoss Tools plugins that I think are worth mentioning.

OpenShift

OpenShift Container Platform 4.2 support

With the new OpenShift Container Platform (OCP) 4.2 now available (see this article), even if this is a major shift compared to OCP 3, JBoss Tools is compatible with this major release in a transparent way. Just define your connection to your OCP 4.2 based cluster as you did before for an OCP 3 cluster, and use the tooling !

CodeReady Containers 1.0 Server Adapter

A new server adapter has been added to support the next generation of CodeReady Containers 1.0. While the server adapter itself has limited functionality, it is able to start and stop the CodeReady Containers virtual machine via its crc binary. Simply hit Ctrl+3 (Cmd+3 on OSX) and type new server, that will bring up a command to setup a new server.

crc server adapter

Enter crc in the filter textbox.

You should see the Red Hat CodeReady Containers 1.0 server adapter.

crc server adapter1

Select Red Hat CodeReady Containers 1.0 and click the Next button.

crc server adapter2

All you have to do is set the location of the CodeReady Containers crc binary file, the pull secret file location (the pull secret file can be downloaded from https://cloud.redhat.com/openshift/install/crc/installer-provisioned).

crc server adapter3

Once you’re finished, a new CodeReady Containers server adapter will then be created and visible in the Servers view.

crc server adapter4

Once the server is started, a new OpenShift connection should appear in the OpenShift Explorer View, allowing the user to quickly create a new Openshift application and begin developing their AwesomeApp in a highly-replicatable environment.

crc server adapter5

Server tools

Wildfly 18 Server Adapter

A server adapter has been added to work with Wildfly 18. It adds support for Java EE 8 and Jakarta EE 8.

EAP 7.3 Beta Server Adapter

A server adapter has been added to work with EAP 7.3 Beta.

Hibernate Tools

Hibernate Runtime Provider Updates

A number of additions and updates have been performed on the available Hibernate runtime providers.

Runtime Provider Updates

The Hibernate 5.4 runtime provider now incorporates Hibernate Core version 5.4.7.Final and Hibernate Tools version 5.4.7.Final.

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.13.Final and Hibernate Tools version 5.3.13.Final.

Platform

Views, Dialogs and Toolbar

The new Quick Search dialog provides a convenient, simple and fast way to run a textual search across your workspace and jump to matches in your code. The dialog provides a quick overview showing matching lines of text at a glance. It updates as quickly as you can type and allows for quick navigation using only the keyboard. A typical workflow starts by pressing the keyboard shortcut Ctrl+Alt+Shift+L (or Cmd+Alt+Shift+L on Mac). Typing a few letters updates the search result as you type. Use Up-Down arrow keys to select a match, then hit Enter to open it in an editor.

quick search
Save editor when Project Explorer has focus

You can now save the active editor even when the Project Explorer has focus. In cases where an extension contributes Saveables to the Project Explorer, the extension is honored and the save action on the Project Explorer will save the provided saveable item instead of the active editor.

save project explorer
"Show In" context menu available for normal resources

The Show In context menu is now available for an element inside a resource project on the Project Explorer.

showin project explorer
Show colors for additions and deletions in Compare viewer

In simple cases such as a 2-way comparison or a 3-way comparison with no merges and conflicts, the Compare Viewer now shows different colors, depending on whether text has been added, removed or modified. The default colors are green, red and black respectively.

compare editor colors

The colors can be customized through usual theme customization approaches, including using related entries in the Colors and Fonts preference page.

Editor status line shows more selection details

The status line for Text Editors now shows the cursor position, and when the editor has something selected, shows the number of characters in the selection as well. This also works in the block selection mode.

These two new additions to the status line can be disabled via the General > Editors > Text Editors preference page.

selection count
selection offset
Shorter dialog text

Several dialog texts have been shortened. This allows you to capture the important information faster.

Previously

long dialog text

Now

short dialog
Close project via middle-click

In the Project Explorer, you can now close a project using middle-click.

Debug

Improved usability of Environment tab in Launch Configurations

In the Environment Tab of the Launch Configuration dialog, you can now double-click on an environment variable name or value and start editing it directly from the table.

environment variable inline editing

Right-clicking on the environment variable table now opens a context menu, allowing for quick addition, removal, copying, and pasting of environment variables.

environment variable context menu
Show Command Line for external program launch

The External Tools Configuration dialog for launching an external program now supports the Show Command Line button.

external tool showcommandline

Preferences

Close editors automatically when reaching 99 open editors

The preference to close editors automatically is now enabled by default. It will be triggered when you have opened 99 files. If you continue to open editors, old editors will be closed to protect you from performance problems. You can modify this setting in the Preferences dialog via the General > Editors > Close editors automatically preference.

In-table color previews for Text Editor appearance color options

You can now see all the colors currently being used in Text Editors from the Appearance color options table, located in the Preferences > General > Editors > Text Editor page.

text editors color intable
Automatic detection of UI freezes in the Eclipse SDK

The Eclipse SDK has been configured to show stack traces for UI freezes in the Error Log view by default for new workspaces. You can use this information to identify and report slow parts of the Eclipse IDE.

freeze event

You can disable the monitoring or tweak its settings via the options in the General > UI Responsiveness Monitoring preference page as shown below.

ui monitor preference

Themes and Styling

Start automatically in dark theme based on OS theme

On Linux and Mac, Eclipse can now start automatically in dark theme when the OS theme is dark. This works by default, that is on a new workspace or when the user has not explicitly set or changed the theme in Eclipse.

Display of Help content respects OS theme

More and more operating systems provide a system wide dark theme. Eclipse now respects this system wide theme setting when the Eclipse help content is displayed in an external browser. A prerequisite for this is a browser that supports the prefers-color-scheme CSS media query.

As of writing this the following browser versions support it:

  • Firefox version 67

  • Chrome version 76

  • Safari version 12.1

help system dark
Help content uses high resolution icons

The Help System as well as the help content of the Eclipse Platform, the Java Development Tooling and the Plug-in Development Environment now use high resolution icons. They are now crisp on high resolution displays and also looks much better in the dark theme.

help system high res
Improved dark theme on Windows

Labels, Sections, Checkboxes, Radio Buttons, FormTexts and Sashes on forms now use the correct background color in the dark mode on windows.

correct backgrounds

General Updates

Interactive performance

Interactive performance has been further improved in this release and several UI freezes have been fixed.

Show key bindings when command is invoked

For presentations, screen casts and learning purposes, it is very helpful to show the corresponding key binding when a command is invoked. When the command is invoked (via a key binding or menu interaction) the key binding, the command’s name and description are shown on the screen.

show key bindings

You can activate this in the Preferences dialog via the Show key binding when command is invoked check box on the General > Keys preference page. To toggle this setting quickly the command 'Toggle Whether to Show Key Binding' can be used (e.g. via the quick access).

Java Developement Tools (JDT)

Java 13 Support

Java 13

Java 13 is out and Eclipse JDT supports Java 13 for 4.13 via Marketplace.

The release notably includes the following Java 13 features:

  • JEP 354: Switch Expressions (Preview).

  • JEP 355: Text Blocks (Preview).

Please note that these are preview language feature and hence enable preview option should be on. For an informal introduction of the support, please refer to Java 13 Examples wiki.

Java Views and Dialogs

Synchronize standard and error output in console

The Eclipse Console view currently can not ensure that mixed standard and error output is shown in the same order as it is produced by the running process. For Java applications the launch configuration Common Tab now provides an option to merge standard and error output. This ensures that standard and error output is shown in the same order it was produced but at the same time disables the individual coloring of error output.

merge process output

Java Editor

Convert to enhanced 'for' loop using Collections

The Java quickfix/cleanup Convert to enhanced 'for' loop is now offered on for loops that are iterating through Collections. The loop must reference the size method as part of the condition and if accessing elements in the body, must use the get method. All other Collection methods other than isEmpty invalidate the quickfix being offered.

foreachcollectionbefore
foreachcollectionquickfix
foreachcollectionafter
Initialize 'final' fields

A Java quickfix is now offered to initialize an uninitialized final field in the class constructor. The fix will initialize a String to the empty string, a numeric base type to 0, and for class fields it initializes them using their default constructor if available or null if no default constructor exists.

finalquickfix1
finalquickfix2
Autoboxing and Unboxing

Use Autoboxing and Unboxing when possible. These features are enabled only for Java 5 and higher.

autoboxing unboxing feature
Improved redundant modifier removal

Remove redundant modifier now also removes useless abstract modifier on the interfaces.

abstract removal feature

For the given code:

abstract removal before

You get this:

abstract removal after
Javadoc comment generation for module

Adding a Javadoc comment to a Java module (module-info.java) will result in automatic annotations being added per the new module comment preferences.

modulejavadocprefs

The $(tags) directive will add @uses and @provides tags for all uses and provides module statements.

modulejavadoc
Chain Completion Code Assist

Code assist for "Chain Template Proposals" will be available. These will traverse reachable local variables, fields, and methods, to produce a chain whose return type is compatible with the expected type in a particular context.

The preference to enable the feature can be found in the Advanced sub-menu of the Content Assist menu group (Preferences > Java > Editor > Content Assist > Advanced) .

chain completion

Java Formatter

Remove excess blank lines

All the settings in the Blank lines section can now be configured to remove excess blank lines, effectively taking precedence over the Number of empty lines to preserve setting. Each setting has its own button to turn the feature on, right next to its number control. The button is enabled only if the selected number of lines is smaller than the Number of empty lines to preserve, because otherwise any excess lines are removed anyway.

formatter remove excess blank lines
Changes in blank lines settings

There’s quite a lot of changes in the Blank lines section of the formatter profile.

Some of the existing subsections and settings are now phrased differently to better express their function:

  • The Blank lines within class declarations subsection is now Blank lines within type declaration

  • Before first declaration is now Before first member declaration

  • Before declarations of the same kind is now Between member declarations of different kind

  • Before member class declarations is now Between member type declarations

  • Before field declarations is now Between field declarations

  • Before method declarations is now Between method/constructor declarations

More importantly, a few new settings have been added to support more places where the number of empty lines can be controlled:

  • After last member declaration in a type (to complement previously existing Before first member declaration setting)

  • Between abstract method declarations in a type (these cases were previously handled by Between method/constructor declarations)

  • At end of method/constructor body (to complement previously existing At beginning of method/constructor body setting)

  • At beginning of code block and At end of code block

  • Before statement with code block and After statement with code block

  • Between statement groups in 'switch'

Most of the new settings have been put in a new subsection Blank lines within method/constructor declarations.

formatter new blank lines settings

JUnit

JUnit 5.5.1

JUnit 5.5.1 is here and Eclipse JDT has been updated to use this version.

Debug

Enhanced support for --patch-module during launch

The Java Launch Configuration now supports patching of different modules by different sources during the launch. This can be verified in the Override Dependencies…​ dialog in the Dependencies tab in a Java Launch Configuration.

launch dependencies
enhanced patch module

Java Build

Full build on JDT core preferences change

Manually changing the settings file .settings/org.eclipse.jdt.core.prefs of a project will result in a full project build, if the workspace auto-build is on. For example, pulling different settings from a git repository or generating the settings with a tool will now trigger a build. Note that this includes timestamp changes, even if actual settings file contents were not changed.

For the 4.13 release, it is possible to disable this new behavior with the VM property: -Dorg.eclipse.disableAutoBuildOnSettingsChange=true. It is planned to remove this VM property in a future release.

And more…​

With the new OpenShift Container Platform (OCP) 4 now available (see this article), even if this is a major shift compared to OCP 3, JBoss Tools is compatible with this major release in a transparent way. Just define your connection to your OCP 4 based cluster as you did before for an OCP 3 cluster, and use the tooling !

Server tools

Wildfly 17 Server Adapter

A server adapter has been added to work with Wildfly 17. It adds support for Java EE 8.

Hibernate Tools

New Runtime Provider

The new Hibernate 5.4 runtime provider has been added. It incorporates Hibernate Core version 5.4.3.Final and Hibernate Tools version 5.4.3.Final

Runtime Provider Updates

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.10.Final and Hibernate Tools version 5.3.10.Final.

Maven

Maven support updated to M2E 1.12

The Maven support is based on Eclipse M2E 1.12

Platform

Views, Dialogs and Toolbar

Import project by passing it as command-line argument

You can import a project into Eclipse by passing its path as a parameter to the launcher. The command would look like eclipse /path/to/project on Linux and Windows, or open Eclipse.app -a /path/to/project on macOS.

pass directory to launcher
Launch Run and Debug configurations from Quick Access

From the Quick Access proposals (accessible with Ctrl+3 shortcut) you can now directly launch any of the Run or Debug configurations available in your workspace.

run debug quickaccess
For performance reasons, the extra Quick Access entries are only visible if the org.eclipse.debug.ui bundle was already activated by some previous action in the workbench such as editing a launch configuration, or expanding the Run As…​ menus.

Themes and Styling

Improved View Menu Icon

The icon used for the view menu has been improved. It is now crisp on high resolution displays and also looks much better in the dark theme.

Compare the old version at the top and the new version at the bottom:

view menu
High resolution images drawn on Mac

On Mac, images and text are now drawn in high resolution during GC operations. You can see crisp images on high resolution displays in the editor rulers, forms, etc in Eclipse.

Compare the old version at the top and the new version at the bottom:

hidpi mac old behavior
hidpi mac new behavior
Table/Tree background lines shown in dark theme on Mac

In dark theme on Mac, the Table and Trees in Eclipse now show the alternating dark lines in the background when setLinesVisible(true) is set. Earlier they had a gray background even if line visibility was true.

Example of a Tree and Table in Eclipse with alternating dark lines in the background:

dark theme alternating lines

Equinox

When the Equinox OSGi Framework is launched the installed bundles are activated according to their configured start-level. The bundles with lower start-levels are activated first. Bundles within the same start-level are activated sequentially from a single thread.

A new configuration option equinox.start.level.thread.count has been added that enables the framework to start bundles within the same start-level in parallel. The default value is 1 which keeps the previous behavior of activating bundles from a single thread. Setting the value to 0 enables parallel activation using a thread count equal to Runtime.getRuntime().availableProcessors(). Setting the value to a number greater than 1 will use the specified number as the thread count for parallel bundle activation.

The default is 1 because of the risk of possible deadlock when activating bundles in parallel. Extensive testing must be done on the set of bundle installed in the framework before considering enabling this option in a product.

Java Developement Tools (JDT)

The settings can be found in the Profile Editor (Preferences > Java > Code Style > Formatter > Edit…​) under the White space > Control statements > 'switch' subsection.

formatter switch
Split Switch Case Labels

As Java 12 introduced the ability to group multiple switch case labels into a single case expression, a quick assist is provided that allows these grouped labels to be split into separate case statements.

split switch case labels

Java Editor

Show method parameter names on code as code minings

In the Java > Editor > Code Mining preferences, you can now enable the Show parameter names option. This will show the parameter names as code minings in method or constructor calls, for cases where the resolution may not be obvious for a human reader.

For example, the code mining will be shown if the argument name in the method call is not an exact match of the parameter name or if the argument name doesn’t contain the parameter name as a substring.

parameter name codeminings
Show number of implementations of methods as code minings

In the Java > Editor > Code Mining preferences, selecting Show implementations with the Show References (including implementations) for → Methods option now shows implementations of methods.

method implementation codeminings

Clicking on method implementations brings up the Search view that shows all implementations of the method in sub-types.

method implementation codeminings click
Open single implementation/reference in editor from code mining

Additional quick fixes for service provider constructors

Appropriate quick fixes are offered when a service defined in a module-info.java file has a service provider implementation whose no-arg constructor is not visible, or is non-existent.

service provider create constructor
service provider change constructor visibility
Template to create Switch Labeled Statement and Switch Expressions

The Java Editor now offers new templates for the creation of switch labeled statements and switch expressions. On a switch statement, three new templates: switch labeled statement, switch case expression and switch labeled expression are available as shown below. These new templates are available on Java projects having compliance level of Java 12 or above.

switch labeled statement
switch case expression
switch labeled expression

If switch is being used as an expression, then only switch case expression and switch labeled expression templates are available as shown below:

switch expression templates

Java Views and Dialogs

Enable comment generation in modules and packages

An option is now available to enable/disable the comment generation while creating module-info.java or package-info.java.

module info comment generation check box

Quick fix to open all required closed projects

A quick fix to open all required closed projects is now available in the Problems view.

quickfix open missing projects problem view
quickfix open missing projects
New UI for configuring Module Dependencies

The Java Build Path configuration now has a new tab Module Dependencies, which will gradually replace the options previously hidden behind the Is Modular node on other tabs of this dialog. The new tab provides an intuitive way for configuring all those module-related options for which Java 9 had introduced new command line options like --limit-modules etc.

module dependencies cropped

The dialog focuses on how to build one Java Project, here "org.greetings".

Below this focus module, the left hand pane shows all modules that participate in the build, where decorations A and S mark automatic modules and system modules, respectively. The extent of system modules (from JRE) can be modified with the Add System Module…​ and Remove buttons (corresponds to --add-modules and --limit-modules).

When a module is selected in the left hand pane, the right hand pane allows to configure the following properties for this module:

Read Module:

Select additional modules that should be accessible from the selected module (corresponds to --add-reads)

Expose Package:

Select additional packages to be exposed ("exports" or "opens") from the selected module (corresponds to --add-exports or --add-opens)

Patch with:

Add more packages and classes to the selected module (corresponds to --patch-module)

Java Compiler

Experimental Java index retired

Eclipse 4.7 introduced a new experimental Java index which was disabled by default.

Due to lack of resources to properly support all Java 9+ language changes, this index is not available anymore starting with Eclipse 4.12.

The preference to enable it in Preferences > Java is removed and the old index will be always used.

Preferences > Java > Rebuild Index button can be used to delete the existing index files and free disk space.

Debug

'Run to Line' on Ctrl+Alt+Click in annotation ruler

A new shortcut, Ctrl+Alt+Click, has been added to the annotation ruler that will invoke the 'Run to Line' command and take the program execution to the line of invocation.

run to line

Check out our new branding for Eclipse 2019-03. We’re now Red Hat CodeReady Studio 12 Integration Stack.

crstudio12

JBoss Tools Integration Stack 4.11.0.Final / Red Hat CodeReady Studio Integration Stack 12.11.0.GA

All of the Integration Stack components have been verified to work with the same dependencies as JBoss Tools 4.11 and Red Hat CodeReady Studio 12.

What’s new for this release?

DataVirtualization support from Teiid Designer is no longer available through the Integration Stack. It can be installed directly from Teiid Designer

This release has an updated BPMN2 Modeler and jBPM/Drools/KIE.

Released Tooling Highlights

Business Process and Rules Development

BPMN2 Modeler Known Issues

See the BPMN2 1.5.1.Final Known Issues Section of the Integration Stack 12.11.0.GA release notes.

Drools/jBPM6 Known Issues

See the Drools 7.21.0.Final Known Issues Section of the Integration Stack 12.11.0.GA release notes.

What’s an Integration Stack?

Red Hat CodeReady Studio Integration Stack is a set of Eclipse-based development tools. It further enhances the IDE functionality provided by Developer Studio, with plug-ins specifically for use when developing for other Red Hat products. It’s where BRMS tooling is aggregated. The following frameworks are supported:

Red Hat Business Process and Rules Development

Business Process and Rules Development plug-ins provide design, debug and testing tooling for developing business processes for Red Hat BRMS and Red Hat BPM Suite.

  • BPEL Designer - Orchestrating your business processes.

  • BPMN2 Modeler - A graphical modeling tool which allows creation and editing of Business Process Modeling Notation diagrams using graphiti.

  • Drools - A Business Logic integration Platform which provides a unified and integrated platform for Rules, Workflow and Event Processing including KIE.

  • jBPM - A flexible Business Process Management (BPM) suite.

The JBoss Tools website features tab

Don’t miss the Features tab for up to date information on your favorite Integration Stack components.

Installation

The easiest way to install the Integration Stack components is through the stand-alone installer or through our JBoss Tools Download Site.

For a complete set of Integration Stack installation instructions, see Integration Stack Installation Guide

Let us know how it goes!

Paul Leacu.

JBoss Tools 4.11.0 and Red Hat CodeReady Studio 12.11 for Eclipse 2019-03 are here waiting for you. Check it out!

crstudio12

Installation

Red Hat CodeReady Studio comes with everything pre-bundled in its installer. Simply download it from our Red Hat CodeReady product page and run it like this:

java -jar devstudio-<installername>.jar

JBoss Tools or Bring-Your-Own-Eclipse (BYOE) CodeReady Studio require a bit more:

This release requires at least Eclipse 4.11 (2019-03) but we recommend using the latest Eclipse 4.11 2019-03 JEE Bundle since then you get most of the dependencies preinstalled.

Once you have installed Eclipse, you can either find us on the Eclipse Marketplace under "JBoss Tools" or "Red Hat CodeReady Studio".

For JBoss Tools, you can also use our update site directly.

http://download.jboss.org/jbosstools/photon/stable/updates/

What is new?

Our main focus for this release was improvements for container based development and bug fixing. Eclipse 2019-03 itself has a lot of new cool stuff but let me highlight just a few updates in both Eclipse 2019-03 and JBoss Tools plugins that I think are worth mentioning.

OpenShift 3

New OpenShift connection helper

When you need to defined a new OpenShift connection, you need to provide the following information:

  • cluster URL

  • username and password or token

If you’ve already logged in your cluster through the OpenShift Web Console, you can copy an oc command in the clipboard that contains both the cluster URL and your token.

So, from now, there is a new option that allows you to initialize the wizard fields from the copied oc command:

connection wizard paste

Click on the Paste Login Command button and the fields will be initialized:

connection wizard paste1

Error Log view added to Platform

The Error Log view has been moved from the PDE project to the Platform project. See bug 50517 for details.

Copy to clipboard in Installation Details

A copy to clipboard action has been added to all tabs of the Installation Details dialog.

copy installation details
Copy & paste of Environment Variables

The Environment tab in a Launch configuration dialog supports copy & paste actions now. The environment variables are transferred as text data, so it is not only possible to copy & paste between two different launch configurations, but also between the launch configuration and e.g. some text editor or the command line.

env var copy paste

This feature is available in all launch configurations which use the common Environment tab.

When Eclipse IDE is started for the first time or with a new workspace, it may not be intuitive for new users on how to proceed. To help the users in getting started, the following useful links have been provided to add a project to the workspace:

  • Perspective specific project creation wizard

  • Generic New Project wizard

  • Import projects wizard

service provider proposal
service provider linked proposal

Java Formatter

Line wrapping settings for binary operators

Instead of a single line wrapping setting for binary expressions, there’s now a whole section of settings for various kinds of binary operators (multiplicative, additive, logical, etc.). There are settings for relational (including equality) and shift operators, which were not covered by the old setting. Also, string concatenation can now be treated differently from arithmetic sum.

The settings can be found in the Profile Editor (Preferences > Java > Code Style > Formatter > Edit…​) under the Line Wrapping > Wrapping settings > Binary expressions subsection.

formatter wrap binary expressions
White space settings for binary operators

The white space around operators in binary expressions can now be controlled separately for different groups of operators, consistent with the line wrapping settings.

The new Binary operators sub-section has been added under White Space > Expressions in the Formatter profile editor.

formatter spaces binary expressions
Wrapping setting for chained conditional expressions

A chain of nested conditional expressions (using ternary operator) can be now wrapped as a single group, with all of them indented at the same level. It’s only possible for right-sided nesting.

Find the Chained conditionals setting in the Profile Editor under the Line Wrapping > Wrapping settings > Other expressions subsection.

formatter wrap chained conditionals
Indent Javadoc tag descriptions

The Formatter Profile has a new setting that indents wrapped Javadoc tag descriptions. It’s called Indent other tag descriptions when wrapped, in contrast to the preexisting Indent wrapped @param/@throws descriptions setting. It affects tags like @return or @deprecated.

The settings can be found in the Profile Editor (Preferences > Java > Code Style > Formatter > Edit…​) under the Comments > Javadocs section.

formatter indent tags
