I'll try to reply to the last 3 posts... Unfortunately the code uses compiled classes from other modules. So I can't change the phase to prior to compile, if I do that then it doesn't generate the sources.
I did find a way to generate sources instead of class files as I agree that is a lot nicer...its not quite as easy as javassist but close enough. However I could not find any combination of moving phases around/etc to make this work...as I mentioned above if I changed the exec plugin phase to be prior to compile then it didn't do anything so there was no generated sources to compile. It seems Maven just just does not like subprocesses that generate more sources using the compiled code. I will look at the above sample projects to see what I missed. For now I have changed things so that I put my generated code right in the src/main/java folder then wrap the exec plugin in a profile so I can manually run that when needed. Not ideal but its working. Will investigate the other projects. -Dave On Thu, Apr 6, 2017 at 1:27 PM, Robert Patrick <robert.patr...@oracle.com> wrote: > I also built a little sample project where I simulated a generated class > using the maven-resources-plugin to copy a class into the target/classes > directory during the process-resources phase.
