Version 3.8.0 of the maven-compiler-plugin supports a multiReleaseOutput option
which can compile classes directly to the appropriate
META-INF/versions/{release} directory, which is very nice. What I don’t see,
though, is how to tell it to use the previous release as its dependency. That
is, given:
src
|—— main
|—— java
|—— java9
\—— java11
These directories will be compiled to:
target/classes, target/classes/META-INF/9 and target/classes/META-INF/11. But
when I compile that last directory, I want to include target/classes/META-INF/9
in my class path, and I don’t see an obvious way to do it. It would be great if
the plugin realized that this was necessary, but is there a way to configure it?
Thanks,
Russ
