Happy to announce 4.21.2.AM1 (Developer Milestone 1) build for Eclipse 2021-09.

Downloads available at JBoss Tools 4.21.2.AM1.

What is New?

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

Quarkus Tools

Quarkus stream selection in the new Quarkus project wizard

When a new Quarkus project/module is to be generated, it is now possible to select the Quarkus stream (see this article) on which the generated application will be based on.

By default, the recommended (latest release) will be selected but you can choose another one:


Enhanced code completion in Java files

When you want to define a fallback method thanks to the @Fallback annotation from MicroProfile Fault Tolerance, the code completion is activated on the fallbackMethod member and will propose you available target methods.


Quarkus launch configuration workspace resolution

When you define a Quarkus launch/debug configuration, it is linked to a specific project from your workspace. If this project has a dependency on another project from the workspace, it will be resolved against the workspace and you don’t have to install the dependency in the local Maven/Gradle cache so that it can be resolved.

Hibernate Tools

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

Runtime Provider Updates

The Hibernate 5.6 runtime provider now incorporates Hibernate Core version 5.6.1.Final and Hibernate Tools version 5.6.1.Final.

The Hibernate 5.4 runtime provider now incorporates Hibernate Core version 5.4.8.Final and Hibernate Tools version 5.4.8.Final.

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.24.Final and Hibernate Tools version 5.3.24.Final.

Apache Log4j CVE-2021-44228 statement

A remote code execution vulnerability in the Apache Log4j 2 Java library dubbed Log4Shell (see https://logging.apache.org/log4j/2.x/index.html#News or https://nvd.nist.gov/vuln/detail/CVE-2021-44228) has been releaved to the public audience on Friday Dec 9th, 2021.

We’ve released new versions of JBoss Tools and Red Hat CodeReady Studio that switches the version of Apache Log4j to 2.16.0.

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



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 4.21 (2021-09) but we recommend using the latest Eclipse 4.21 2021-09 JEE Bundle

since then you get most of the dependencies preinstalled.

Java11 is now required to run Red Hat Developer Studio or 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" or "Red Hat CodeReady Studio".

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