What is New?

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


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.

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

JBoss Tools 4.19.1 and Red Hat CodeReady Studio 12.19.1 for Eclipse 2021-03 are here waiting for you. Check it out!



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 4.19 (2021-03) but we recommend using the latest Eclipse 4.19 2021-03 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.


What is new?

Our main focus for this release was an improved tooling for the Quarkus framework, improvements for container based development and bug fixing.


Improved OpenShift Application explorer

When the OpenShift cluster has no applications or projects, user is required to create them. However, it may not be obvious for the user that the corresponding function is available from a sub menu of the New context menu.

So now, a link will be provided within the tree with an explanation message.

If no projects are available, user will be guided to create one:

application explorer enhanced navigation1

If no applications are available in a project, user will be guided to create a new component:

application explorer enhanced navigation2
