First, you need to install Homebrew:


After that, and if you want a specific Java version, you should add AdoptOpenJDK tap and install it from there. For instance, if we like an OpenJDK 11 instance, we should type:


If all works as expected, you should have a new Java 11 environment running:

Eclipse IDE for Enterprise Java Developers

Eclipse offers collections of plugins-denominated Packages;each package is a collection of common plugins aimed for a particular development need. Hence, to simplify the process, you can download Eclipse IDE for Enterprise Java Developers directly.

On Mac, you will download a convenient .dmg file that you can drag and drop into the Applications folder.

The result is a brand new Eclipse installation with Enterprise Java (Jakarta EE) support.

JBoss Tools

To install the 'Enterprise Java' features to your Eclipse installation, go to JBoss Tools main website at https://tools.jboss.org/ — you should double check the compatibility with your Eclipse version before installing. Since Eclipse is launching new versions each quarter, the preferred way to install the plugins is by adding the updated URL.

First, go to:


And add the JBoss Tools URL http://download.jboss.org/jbosstools/photon/development/updates/

After that, you should select the individual features, a minimal set of features for developers aiming Jakarta EE is:

Finally, you should accept licenses and restart your Eclipse installation.

Wildfly 16

Wildfly distributes the application server in zip or tgz files. After getting the link you could do the install process from the CLI. For example, if you wanna create your Wildfly directory at ~/opt/, you should execute the following commands:


It is also convenient to add an administrative user that allows the creation of DataSources, Java Mail destinations, etc. For instance, and again using ~/opt/ as a basis:

The script will ask basic details like username, password, and consideration on cluster environments; in the end, you should have a configured Wildfly instance ready for development. To start the instance, just type:


To check your administrative user, go to http://localhost:9990/console/index.html.

If you wanna go deep on server's configuration, Eclipse allows you to open the standalone.xml configuration file directly from the IDE, just check if the application server is stopped, otherwhise your configuration changes will be deleted.

Testing the Environment

Check your pom.xml for Java 11 capabilities, specifically Maven compiler source configuration. The complete pom.xml file should be similar to this:

Since the IDE and application server are compatible with Java 11, it is possible to use local type inference in JAX-RS.

To test this application, I've created a nano-application using an Archetype for Java EE 8. The application server and IDE support Java 11, and the deployment works as expected directly from the IDE.


And there you have it! Hope you enjoyed.
