yes, the package name has nothing to do with the maven artifact ID. To my knowledge, there can only be one combination of groupId+artifactId+version+classifier+type. Normally that is something like: foo/bar/baz/1.0/baz-javadoc.jar

But I think you can use something like the build-helper to attach additional artifacts: https://www.mojohaus.org/build-helper-maven-plugin/attach-artifact-mojo.html

Fair enough, I was hoping for some sort of config option to make my life easy. I'll just give them all different classifiers instead.

I guess it could be solved in the RPM builder plugin too. PRs welcome 😁

Not sure it that works in your case, but you also can set the classifier: https://ctron.github.io/rpm-builder/rpm-mojo.html#classifier
