> Assume that we have a bundle that exports a package which contains no java classes.
> If these packages are part of the exported from an API region, when generating the APIs jar, a warning is generated for each jar, since:
> - there are no java source files for the sources jar
> - there are no class file for the api jar
> - there are no javadoc files generated for the javadoc jar
> To my understanding, it is legal to export such packages, as importers will have access to the resources included in those packages.
> I see a couple of ways out:
> 1. Track packages that contain only non-java resources. For these specifically, update the checks as follows:
> - sources jar must contain files, but not java sources
> - api jar must contain files, but not java classes
> - javadoc jar must not contain any files
> 2. Skip checking for packages that only contain non-java resources. This is I think wrong, as at development time you will need those resources.
