I’ve messed around a lot to get JRebel to work with the Embedded-Glassfish 4 maven plugin. Especially, as I thought maven would spawn an own JVM and I had to alter the domain.xml for it to work… I was soooo wrong.

Simply adding the JRebel Plugin to my pom.xml and adjusting my MAVEN_OPTS was enough.

Thats my pom.xml

and I simply start the app with

mvn clean package
MAVEN_OPTS="-noverify -javaagent:/home/domdorn/.jrebel/jrebel.jar" mvn embedded-glassfish:run
