gwt-dev dependencies were moved from external constant to maven_jar() exported_deps dependency in I54df92daf. As the consequence, maven_jar makes from it java_library instead of prebuil_jar. As the consequence java_library without sources and resources doesn't expose output jar. This broke java_doc() rule in gwtui-api that makes use of $(location) macro. This macros is failing on libraries without own output jar. To rectify it, expose intermediate prebuilt_jar from maven_jar() rule with the same visibility scope as the final artifact. Now it can be used in java_doc() as it exposes output jar and exported_deps aren't needed in this context. Change-Id: I6168fda0aba8827063958f80c6e2828b0a6941f8
