This is the case for play-services-7.0 and 7.3.0 because the ClasspathModifierLifecycleParticipant blindly creates an empty file called classes.jar so that it can be added to the classpath for the compiler. It is normally later replaced by a real classes.jar as the AAR is extracted in GenerateSources.

The solution is to create a a proper empty jar file instead of a zero length file.

This fix work with JDK 1.8 and doesn't work with JDK 1.6 (as stated in plugin requirements).
instead of java.util.zip.ZipException: zip file is empty
I got java.util.zip.ZipException: ZIP file must have at least one entry
