I was playing around with the pom a little bit yesterday when I came across a relatively new maven-compiler-plugin configuration element called <multiReleaseOutput> which can be used to output the compiled classes relative to META-INF/versions/N rather than the root. This looks like it would likely remove the need to use maven-assembly-plugin as an intermediary step.
I found an interesting approach linked in [1] as the multi-release parent strategy with source code at [2]. I attempted to refactor log4j-api to use this pattern, but I couldn't figure out how to make the same pattern work for test classes (which made it impossible to compile log4j-api/src/test/java9). I'm going to continue experimenting a bit with this, but has anyone tried out the more recent multi-version tooling support? We were early users of some things, so I'd imagine tooling has caught up by now.
