I'm using AspectJ on a project I'm working on. As part of the project I was trying to use the "maven-shade-plugin" and the "jarjar-maven-plugin" in order to relocate classes from one jar to another.
In both cases, when I was trying to use the generated JAR, AspectJ failed with the following exception:

I'll appreciate if you could point me out to what I'm doing wrong.
Thanks, Nadav
In the end I didn't use the maven-jarjar-plugin nor maven-shade plugin. I've used JarJar's JAR itself and that's solved the problem (since it doesn't modifiy the JAR with AspectJ during compile).
The answer of the following question describes the solution:
