I don't know if there's an easy way to do this. The plugin class loader is created at runtime via Classworlds, so you can do something like this: URLClassLoader cl = (URLClassLoader) Thread.currentThread().getContextClassLoader();
And then call cl.getURLs(). But this list is probably going to include (in your original words) "crappy stuff". I would question why you're not just executing the Java class directly, rather than via Process.exec(). Wouldn't AgentCompiler.main(cmd); Be a heck of a lot easier than going through these hoops?

The project.getCompileClasspathElements() , gets me the elements of the classpath of the project that the plugin is actually running , but not of the plugin itself , so i had to add plugin dependencies also to the pom.xml where the plugin is configured. Is there a way to get the plugin classpath too ?
