Select the check box for each project that you want to add JRebel to. This will generate rebel.xml and keep it up to date.
Redeploy your application (or restart your standalone application).

Didn’t work?

Using Maven? Use the JRebel Maven plugin to generate the rebel.xml . JRebel Maven instructions.
Running Gradle? Use the JRebel Gradle plugin to generate rebel.xml . JRebel Gradle instructions.
Need to tweak your rebel.xml ? JRebel rebel.xml reference manual has the answers.

Did this Work?

When building your application, rebel.xml should be included within the application archive.

In case of JAR files, rebel.xml should be included in the root folder.
When working with WAR files, the rebel.xml should be located within the WEB-INF/classes folder.
EAR files require a rebel.xml for each internal EAR module (that means JARs and WARs).

Adding JRebel agent to your server or standalone application

How do you run your server?

Via IDE
Locally from command line
On a remote server

Run via IDE

Open JRebel view (View -> Open View -> Search “JRebel”).
Click Startup – Guide.
Click “Run via IDE”.
Select the check-box next to your application server. Doing this will automatically run it with the required JVM arguments.

Good to know

Not running your server from the IDE? Follow another application server startup method.

Did this work?

When successful, you will see the JRebel banner in the console right at server startup. This is what the JRebel banner should look like:
