Happy to announce 4.24.0.Final build for Eclipse 2022-06.

Downloads available at JBoss Tools 4.24.0.Final.

What is New?

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

Quarkus Tools

Improvement to the new Quarkus project wizard

When the new Quarkus project wizard was initially design, there were a few Quarkus extensions so it was not difficult to find one from the total list. Now that the Quarkus ecosystem is growing fast, it was difficult even of the extensions were grouped into categories.

In order to cope with this issue, the extensions and categories are now displayed in a tree (first level is categories, second level is extensions).

This new tree can now be filtered through a text field. If user enter some characters, only extensions matching this filter will be displayed in the tree.

JBoss Tools 4.23.0 for Eclipse 2022-03 is here waiting for you. Check it out!

We highly recommand to download or update to this latest version.

Note for Red Hat CodeReady Studio users

The Red Hat CodeReady Studio product has reached end of life. The last release for the product was 12.21.3.GA. So there is no equivalent version of Red Hat CodeReady Studio for this version of JBoss Tools. Existing users of Red Hat CodeReady Studio can upgrade to this version of JBoss Tools.

For more information, see this article

Installation

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

This release requires at least Eclipse 4.23 (2022-03) but we recommend using the latest Eclipse 4.23 2022-03 JEE Bundle

since then you get most of the dependencies preinstalled.

Java11 is now required to run JBoss Tools (this is a requirement from Eclipse 4.17). So make sure to select a Java11 JDK in the installer. You can still work with pre-Java11 JDK/JRE and projects in the tool.

Once you have installed Eclipse, you can either find us on the Eclipse Marketplace under "JBoss Tools".

You can also use our update site directly.

Quarkus Tools

Qute templates support

Qute templates support has been added. This allows Quarkus developers to get enhanced editing experience to Qute templates located in their projects.

A Qute template is any file located under src/main/resources/templates and with the html, yaml, yml, json or txt extension.

Qute support is enabled on any project that has a dependency on the Qute library.

You can generate a Qute enabled project with the Quarkus project wizard and choosing the RESTEasy Classic Qute extension

quarkus33

Qute features

Features included into the Qute support are:

  • Integration between Java files and Qute templates files

  • Method parameter support in Qute template files

  • Java Type Hover Support for Qute Templates

  • Linked Editing Range Support in Qute Templates

  • Qute Section Completion

  • Support for Qute Validation

  • Completion for Qute Value Resolvers

  • Support for @TemplateExtension Methods

  • Support for Directly Injecting Beans into Qute Templates

Integration between Java files and Qute templates files

Any reference to a Qute template file from a Java file show the option to generate the Qute template file (if the Qute template file has not been found in the project) or navigate to the Qute template file.

quarkus34

Method parameter support in Qute template files

The Qute language server has support for built-in and user-defined Java classes, including parameter completion and validation for their methods. Take advantage of this to easily avoid Java related mistakes.

quarkus35

Java Type Hover Support for Qute Templates

When hovering over an expression in a Qute template, the Java type (built-in or user defined) will be displayed.

quarkus36

Linked Editing Range Support in Qute Templates

Similar to most language, linked editing is now supported for Qute templates , allowing for simultaneous renaming of multiple parameter expressions.

quarkus37

Qute Section Completion

Qute templates use sections in its templating language to power any logic required when compiling and displaying the resulting document. To support this, the extension’s Qute support populates a completion list with all available Qute sections, along with any parameters they take and a small code snippet of its usage.

quarkus38

Support for Qute Validation

Java and Qute validation is included for Qute templates with Quarkus Tools, including diagnostics and quick fix suggestions.

quarkus39

The developer has the ability to disable this validation in their settings through the WindowPreferencesJBoss ToolsQute.

quarkus40

The second table contains a list of Qute templates (as regular expressions) for which validation will be excluded.

If any of the available validation is disturbing your development, you can disable Qute validation for the file project with a single click, using a “Quick Fix” that appears on every Qute related diagnostic

quarkus41

Completion for Qute Value Resolvers

Paired with corresponding Java methods, built-in Java classes also have built-in Qute value resolvers made available by the Qute templating engine that is evaluated and outputs, or resolves to, a value. Quarkus Tools supports completion, hover and snippet generation for these built-in value resolvers.

quarkus42

Support for @TemplateExtension Methods

Template extension methods are used to extend the set of accessible properties of data objects. Qute support in Quarkus Tools has support for marked @TemplateExtension Java methods, which extend a given data model.

quarkus43

Support for Directly Injecting Beans into Qute Templates

A CDI bean annotated with @Named can be referenced in any template through cdi and/or inject namespaces. Quarkus Tools provides completion and definition navigation support for Beans.

What is new?

Our main focus for this release was an improved tooling for container based development and bug fixing.

OpenShift

Operator based services

When developing cloud native applications on OpenShift, developer may need to launch services (databases, messaging system,…​) that the application under development may need to connect to. The OpenShift tooling allowed to launch such services but it was based on the service catalog which is not available anymore on OpenShift 4.

The new feature is based on operators which is the devops way of installing and managing software on Kubernetes clusters. So when you want to launch a service for your application, you will have to choose from the list of installed operators on your cluster and then select type of deployment you want.

In the following example, there are two operators installed on our cluster: the Strimzi operator for setting up Kafka clusters on Kubernetes and a Postgresql operator.

For each operator, we can select the type of deployment we want to setup. For each type of deployment, specific parameters may be specified. In this example, we decided to set the replicas number to 4 for a Kafka cluster.

operator based services3

After you’ve entered the name of your service, it will appear in the application explorer view:

operator based services2

Hibernate Tools

Hibernate Runtime Provider Updates

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

New Runtime Provider

A new runtime provider has been added for Hibernate 5.6. It incorporates Hibernate Core version 5.6.0.Beta2 and Hibernate Tools version 5.6.0.Beta2. This runtime is in preview mode.

Runtime Provider Updates

The Hibernate 5.5 runtime provider now incorporates Hibernate Core version 5.5.7.Final and Hibernate Tools version 5.5.7.Final.

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.22.Final and Hibernate Tools version 5.3.22.Final.

Platform

Views, Dialogs and Toolbar

New clean message dialog api

A new API in the class PlainMessageDialog is introduced. It uses a builder pattern to create an immutable instance of PlainMessageDialog. It has a clean API and consists of methods for e.g. the button labels, the message and the image.

Example Usage: int answer = PlainMessageDialog.getBuilder(myShell, "The new dialog").image(SWT.ICON_Question).message("Like it?").buttLabels(Arrays.asList(IDialogConstants.YES_LABEL, IDialogConstants.NO_LABEL)).build().open();

plain message dialog usage
Accepted licenses remembered permanently

Before accepted licenses were only remembered during runtime and not persisted between restarts. The user selection of accepted licenses is now persisted between restarts.

Export certificate during installation

When installing a software into the workbench and the software is signed but with an untrusted certificate, the dialog to review trusted certificates now shows a button to 📥 Export…​ the selected certificate into their own *.der file. This can facilitate review of the certificate, for example in order to get it audited by some other external service, tool or workflow before approval.

Quick Search mentions max occurrences reached

The Quick Search dialog features a label to depict the number of matches that were found. Additionally, if the result set exceeds a now configurable limit, the label shows that the limit has been reached and the search process stops. Besides this new "Max Results" configuration option, the preference page has been overhauled with information decorators to describe the properties in more detail.

Preferences

History for derived files

The Local history for derived files is now disabled by default. The behaviour can now be configured to the previous (enabled) behaviour in Preferences > General > Workspace > Local History page, by checking the History for derived files checkbox.

Derived files are for example automatically created as the output of java annotation processing or XText. As they are automatically created one could also recreate old versions of the output by compiling older versions of the input, thereby wasting time and space to store the history of the derived files for most users.

General Updates

Eclipse support for Mac AArch64(Arm64)

Eclipse SDK downloads for the Mac AArch64(Arm64) architecture are now available. Please note that a Mac AArch64 JVM is required to run Eclipse for Mac AArch64. Eclipse for Mac AArch64 will be formally supported in the Target Environments in a future release.

Eclipse and SWT for Mac x86_64 architecture can already run on Apple Silicon hardware under Rosetta translation mode using a x86_64 JVM.

New method create(int style) in GridDataFactory

GridDataFactory contains a new static method create(int style) which returns a new GridDataFactory instance. This method is similar to new GridData(int style).

Minimum Java version for SWT

SWT now requires minimum Java 11 to run SWT.

Ant 1.10.11

Eclipse has adopted Ant version 1.10.11.

Java Developement Tools (JDT)

Java™ 17 Support

Java 17

Java 17 is out and Eclipse JDT supports Java 17 in 4.21 via Marketplace.

The release notably includes the following Java 17 features:

  • JEP 306: Restore Always-Strict Floating-Point Semantics.

  • JEP 406: Pattern Matching for switch (Preview).

  • JEP 409: Sealed Classes (Final).

Please note that preview option should be on for preview language features. For an informal introduction of the support, please refer to Java 17 Examples wiki.

Java™ 16 Support

Java 16

Java 16 is out and Eclipse JDT supports Java 16 in 4.20.

The release notably includes the following Java 16 features:

  • JEP 394: Pattern Matching for Instanceof (Final).

  • JEP 395: Records (Final).

  • JEP 397: Sealed Classes (Second Preview).

Please note that preview option should be on for preview language features. For an informal introduction of the support, please refer to Java 16 Examples wiki.

JUnit

mockito ArgumentMatchers.* added to favorites in Java tooling

Mockito based tests frequently use org.mockito.ArgumentMatchers.*. This has been added to the Java favorites in the preferences under Java > Editor > Content Assist > Favorites. This way the organize imports action in the IDE will automatically add static imports for these classes if you use them in your tests.

BREE update for JDT JUnit runtime bundles

The bundle required execution environment (BREE) for the org.eclipse.jdt.junit.runtime and org.eclipse.jdt.junit4.runtime bundles is now JavaSE-1.8.

Java Editor

Use StringBuilder instead of StringBuffer clean up

A new clean up has been added that converts code to use StringBuilder (added in Java 1.5) rather than StringBuffer which has synchronized methods and is slower than using StringBuilder.

There is a sub-option where changes will only occur to local variables which is on by default. When this sub-option is on, changes will only occur to StringBuffer variables that are local to a method. When a method calls other methods with such variables or assigns to/from fields/parameters, the method contents will not be converted. It is permitted to append StringBuffer fields or parameters to local StringBuffer variables which can then still be converted to StringBuilder.

When the option is selected and the sub-option for local variables is off,all usage of StringBuffer in the selected files are changed to StringBuilder regardless of usage. It should be noted that in this case, the clean up will not track down non-selected classes and methods that are referenced and might require changes to compile successfully.

To apply the clean up, select the Use StringBuilder instead of StringBuffer check box on the Performance tab in your clean up profile. To specify just for local variables, select the Only for local variables check box found just below.

stringbuffer to stringbuilder prefs

For the given code:

stringbuffer to stringbuilder before

One gets:

stringbuffer to stringbuilder after
Convert while to do/while

A new quick-assist has been added to convert appropriate while loops into do/while loops. Appropriate while loops require the first evaluation of the while expression is guaranteed to be true and that the evaluation is passive.

For the following loop:

while to do while before

One is offered:

while to do while after
Extract Superclass Enhancement

The Extract Superclass refactoring has been enhanced to support movement of uninitialized non-static final fields. In the past, a warning was issued for extracting uninitialized non-static final fields as the resultant code would be in error. The refactoring has been enhanced to add additional parameters to the moved constructors and to pass initialization values from the original class constructors.

For the following class:

extract superclass original before

Extracting to Superclass and choosing all fields, one gets:

extract superclass original after

and

extract superclass superclass after
Raw Paste

A new menu item has been added for doing a raw paste when editing Java files. The menu item Raw Paste can be found in the Edit pull-down menu and by right-clicking in the edit window to bring up the context-menu. The menu item performs a paste action but toggles off the smart insert feature, if required, and restores it, if necessary, after the paste. For end-users in smart insert mode, this is the same as doing a Shift+Ctrl+Insert followed by Ctrl+V, followed by Shift+Ctrl+Insert to retoggle into smart insert mode again.

Default Type Filters

Default values have been added to the Java > Appearance > Type Filters preferences. Types matching these filters will be excluded from appearing in the Open Type dialog, content assist, quick fix, and organize imports. These filter patterns do not affect the Package Explorer and Type Hierarchy views.

default type filters
Change project compliance and JRE on using multi-constant case labels

A new quick fix (Ctrl+1) has been added to change the project compliance and JRE when multi-constant case labels are used in a project below Java 14:

change compliance jre multi constant labels

Better type for the local variable creation quick fix

The quick fix Create a new local variable has been enhanced. When it creates a variable that is the expression on which a foreach loop iterates, its type is an array of the type of the loop parameter:

For the given code:

foreach expression type before

One gets:

foreach expression type after
Use instanceof clean up

A new clean up has been added that uses an instanceof expression to check an object against a hardcoded class.

The expression must be a supertype of the targeted class.

One if rather than duplicate blocks that fall through clean up

A new clean up has been added that merges consecutive if statements with same code block that end with a jump statement.

To apply the clean up, select Single 'if' statement rather than duplicate blocks that fall through check box on the Duplicate code tab in your clean up profile.

For the given code:

one falling through if before

One gets:

one falling through if after
Uses String.isBlank() clean up

A new clean up has been added that replaces the check of the emptiness of String.strip() by the use of String.isBlank().

It avoids the cost of the creation of a stripped string.

You may use Java 11 or higher to use it.

In order to apply this cleanup also to trim().isEmpty(), you might consider to replace trim(), which exists since the beginning of Java, with strip() that has been introduced in Java 11 together with isBlank(),

But watch out, trim() and strip() differ: trim() removes leading and trailing characters with an ASCII code up to 32, including some non white space ASCII control characters and missing some Unicode white space characters, whereas strip() removes all and only leading and trailing white space.

To apply the clean up, select String.isBlank()` rather than `String.strip().isEmpty() check box on the Optimization tab (the Performance tab in Eclipse 2021-09) in your clean up profile.

isblank preferences

For the given code:

isblank before

One gets:

isblank after
valueOf() rather than instantiation clean up

A new clean up has been added that replaces unnecessary primitive wrappers instance creations by using static factory methods (valueOf()).

It dramatically improves the space performance.

To apply the clean up, select valueOf() rather than instantiation check box on the Optimization tab (the Performance tab in Eclipse 2021-09) in your clean up profile.

valueof rather than instantiation preferences

For the given code:

valueof rather than instantiation before

One gets:

valueof rather than instantiation after
Primitive rather than wrapper clean up

A new clean up has been added that replaces a primitive wrapper object by the primitive type when an object is not necessary.

The variable must be not null. The result should not make more autoboxing/unboxing than the original code.

To apply the clean up, select Primitive type rather than wrapper class check box on the Optimization tab (the Performance tab in Eclipse 2021-09) in your clean up profile.

primitive rather than wrapper preferences

For the given code:

primitive rather than wrapper before

One gets:

primitive rather than wrapper after
Redundant truth clean up

A new clean up has been added that directly checks boolean values instead of comparing them with true/false.

The operator can be equals, not equals or XOR. The constants can be a literal or a java.lang.Boolean constant. One operand should be primitive so no new null pointer exceptions may occur.

To apply the clean up, select Boolean value rather than comparison check box on the Unnecessary Code tab in your clean up profile.

redundant truth preferences

For the given code:

redundant truth before

One gets:

redundant truth after
Implicit comparator clean up

A new clean up has been added that removes the comparator declaration if it is the default one.

The declared comparator should be an equivalent to the natural order. It removes anonymous class, lambda, Comparator.comparing(), Comparator.naturalOrder() and null. It applies on List.sort(Comparator), Collections.sort(List, Comparator), Collections.max(Collection, Comparator) and Collections.min(Collection, Comparator). If the comparator is used in the method List.sort(Comparator), the method is converted into Collections.sort(List).

To apply the clean up, select Use implicit comparator when possible check box on the Unnecessary Code tab in your clean up profile.

implicit comparator preferences

For the given code:

implicit comparator before

One gets:

implicit comparator after
Initialize array with curly clean up

A new clean up has been added that replaces the new instance syntax by curly brackets to create an array.

It must be an initialization of a declaration. The declaration must have the same type.

To apply the clean up, select Create array with curly when possible check box on the Unnecessary Code tab in your clean up profile.

array with curly preferences

For the given code:

array with curly before

One gets:

array with curly after
Remove variable assignment before return clean up

A new clean up has been added that removes unnecessary local variable declaration or unnecessary variable assignment before a return statement.

An explicit type is added for arrays.

To apply the clean up, select Remove variable assignment before return check box on the Unnecessary Code tab in your clean up profile.

return without assignment preferences

For the given code:

return without assignment before

One gets:

return without assignment after
Replace System.getProperty() calls clean up

A new clean up has been added that replaces certain System.getProperty() calls with alternative Java method calls or constants instead. Using these calls/constants may end up using system defaults (e.g. system default file separator) and thus can no longer be overridden at runtime.

To apply the clean up, select Replace system property with constant check box on the Java Feature tab in your clean up profile. This enables you to check one or more sub-options: File separator, Path separator, Line separator, File encoding, or Boolean property. The last option is used for arbitrary boolean options specified by -Dsome-arbitrary-option.

system properties preferences

For the given code:

system properties before

One gets:

system properties after

Java Compiler

Find external annotations anywhere

External annotations, which are used for annotation based null analysis, can now be associated to unannotated classes more freely.

Previously, all external annotations where declared per build path entry. I.e., whenever a project of yours uses a library for which external annotations exist, you would need to explicitly declare where the corresponding external annotations for this particular library can be found.

A new compiler preference has been added by which you can instruct the compiler to search for external annotations in all build path locations of the current project.

external annotations all locations

When enabled, this strategy will be applied to all class files encountered during compilation.

Some examples, where this option is useful:

  • A project A contains generated sources (in a separate source folder), which are decorated using external annotations in the same project. When project A ships a jar containing also the external annotations, any client of A will immediately see the generated classes with their external annotations applied.

  • When dedicated jars have been created, each containing external annotations for a set of libraries, you only have to add these annotation jars to your build path and enable the new option, without worrying which annotation jar corresponds to which individual dependency (dependencies). The compiler will match external annotations to class files with no further help.

For batch compilation a corresponding option already exists. To match the above strategy in CI-builds, just add the following to the compiler command line (verbatim): -annotationpath CLASSPATH

Java Views and Dialogs

Differentiate search filter for normal imports from static imports

The Search view now supports a new filter dedicated for static imports. Consequently, the existing imports filter is dedicated for non-static imports only. As a result, you will now by default find statically imported references of a class or an interface.

static import filter
Create module-info.java option during New Java Project creation

Create module-info.java option has been moved to the first page of New Java Project creation wizard. This option will be enabled only for Java projects with JRE 9 or above. New Java Project creation wizard will also remember the previous choice made by the user and select this option by default accordingly.

create moduleinfo
Default Java cleanup profile of Eclipse has been updated

The default cleanup profile of the Java development tools has been updated to include more cleanups. All included cleanups have been well tested and proven to be stable in the Eclipse code base. Please see the preference under Java > Clean-up for details.

Debug

Evaluate variables in current execution stack

In debug mode, regardless of the selected stack frame now you can evaluate variables which are in the scope of the current execution stack frame and stack frames below it which are defined in the current focused java class.

debug eval intrim stack
Copy Run Configuration item details

A new Copy button has been added to the Dependencies/Classpath tab of Run Configuration dialog. This can be used to copy the details of the selected item.

configuration copyjars
Debug hover for chain of variables

When hovering over chain of variables, the debug hover will now show the variable value under the cursor.

debug hover chain var

It even works for array length.

What is next?

Having JBoss Tools 4.21.0 and Red Hat CodeReady Studio 12.21.0 out we are already working on the next release.

Enjoy!

Jeff Maury

Happy to announce 4.21.0.AM1 (Developer Milestone 1) build for Eclipse 2021-09.

Downloads available at JBoss Tools 4.21.0 AM1.

What is New?

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

OpenShift

Operator based services

When developing cloud native applications on OpenShift, developer may need to launch services (databases, messaging system,…​) that the application under development may need to connect to. The OpenShift tooling allowed to launch such services but it was based on the service catalog which is not available anymore on OpenShift 4.

The new feature is based on operators which is the devops way of installing and managing software on Kubernetes clusters. So when you want to launch a service for your application, you will have to choose from the list of installed operators on your cluster and then select type of deployment you want.

In the following example, there are two operators installed on our cluster: the Strimzi operator for setting up Kafka clusters on Kubernetes and a Postgresql operator.

For each operator, we can select the type of deployment we want to setup.

operator based services1

After you’ve entered the name of your service, it will appear in the application explorer view:

operator based services2

Hibernate Tools

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

Runtime Provider Updates

The Hibernate 5.5 runtime provider now incorporates Hibernate Core version 5.5.7.Final and Hibernate Tools version 5.5.7.Final.

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.22.Final and Hibernate Tools version 5.3.22.Final.

Enjoy!
