Robert Scholte closed MCOMPILER-361.
------------------------------------
    Resolution: Not A Problem
      Assignee: Robert Scholte

I'll close this as it is not a maven-compiler-plugin issue. The dependency was invalid (missing the magic "Multi-Release:true" entry in the MANIFEST.MF ). Improvements should be done on the maven-jar-plugin.
If somebody wants to improve documentation on this topic, I can reopen it.

> I have struggled with this all day and come to the determination that the compiler plugin is *not* picking up module-info from dependency jars that put it in the multi-release jar location.
> If you reconfigure the dependency to build with module-info at jar root, the dependencies get picked up just fine.
> I've prepared a gist based on two projects I help maintain. org.jruby.jcodings:jcodings and org.jruby:bytelist.
> [https://gist.github.com/headius/30359f2bbd26852ef545fd54f6fef248]
> As you can see, with the jcodings module-info in the "release 9" multi-release jar location, the bytelist module-info is unable to see the exported module.
> This makes the multi-release jar feature largely useless for hiding the module-info, but putting it in the root of the jar affects any projects or libraries that can't understand it.
