In this build, only the ':foo' subproject has had the java plugin applied.

As expected, only the ':foo' project has java-plugin related tasks, e.g. assemble.

However, both the ':foo' and ':foo:bar' subprojects have source sets configured.

Why does the ':foo:bar' subproject have source sets at all? Is this a bug?
