Netbeans Profiler for a Maven project

Question

When I try to attach a Profiler to my project, Netbeans prompts me to choose bewtween my main class and org.codehaus.plexus.classworlds.launcher.Launcher . I was wondering if someone knows which one I should use and why.

Thanks,

org.codehaus.plexus.classworlds.launcher.Launcher is the main class for the maven build. netbeans executes the maven build jvm which in turn via exec-maven-plugin starts the jvm that your main class executes in.

So if you want to profile the build you choose the classworld's Launcher, otherwise you choose your your main class.
