I6168fda0 was trying to provide a workaround for java_doc() rule to
not being able to resolve the location of java_library with exported
dependencies only. The workaround idea was to make intermediate
artifacts visible in maven_jar() definition and use them instead of
java_libraries with exported dependencies only.
Iab67dff9 solved the problem by replacing $(location :foo) macro with
$(classpath :foo) macro. That made the workaround in I6168fda0 not
necessary any more, so that it can be removed.
