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).

Completion Building your project

  1. Open File > Settings and find Compiler.
  2. Make sure Make project automatically is enabled.
  3. And you’re done!

Why do this?

IntelliJ IDEA does not compile classes by default. Use the Make Project command to compile classes and update your application.

JRebel relies upon your IDE to do the compiling. JRebel reloads your compiled .class files and not your .java files. When you change code, JRebel pushes the changed classes and resources to the server without redeploying.
