I believe you might be trying this is a non-bleeding-edge repo. :-)

The problem is not in the bash completion, but in the makefile. This is 
what happens if you do not have exactly one configuration, and are 
standing in the source root directory. :-( This was very recently fixed 
in jdk9, so that it should work even with multiple configurations, or 
when standing in the build output directory. Without any configuration 
at all, this is all you'll ever get, though (because without a 
configuration, make cannot figure out which targets should be available, 
and in a way, "no" targets are available unless you have a configuration).
