This looks good to me! 👍

Could we summarize that there is 3 potential layers to be specified: artifact, package and jar, while rpm is gone now? If all of those are equal, it seems sufficient to specify artifact and repository (e.g. in the case of jcommon). Otherwise if the package name differs from the artifact name, it can be given as package, and I assume jar if there is more than one jar file produced by a package. Looking at httpclient though, jar is equal to artifact, couldn't it be omitted in such a case?

Great, it seems you already made the jar attribute obsolete if it is equal to artifact 👍
