Using the new multi-release jar feature, store compiled
module-info.class files into META-INF/versions/9 instead of the artifact
root. Hopefully, this will break fewer tools which do not support
module-info.class files because any sane tool should not do anything
with files in META-INF because before Java 9 that directory only
contained resources.
Upgrade some Maven plugins to newer versions which do not fail on
module-info.class files
