If you have bundles that are unrelated to each other, then you can conditionally add the modules through a profile. However this probably won’t work if you have B->A and you only want to build B.

Something like this would work:

You can then invoke with mvn -Pone -Ptwo or you can have the profile enabled when a system property is set e.g. -Dui or -Dheadless
