The problems seem to mostly revolve around the fact that they can’t deal with the classes for Java 9. I was surprised that Android is failing on the classes in META-INF/versions/9 as I had assumed that would be an invalid location for a class file prior to Java 9, but that seems not to be the case. The fact that module-info.java turns into a class file also seems to be a problem since the various tools are seeing it and having problems with it.

The Android tools should ignore class files in META/**, at least until 
they are updated to work with multi-release JARs. Have you created a bug 
for them to look at this issue?
