Comment (by sisbell):

 If we look at maven central, we see the later 2017 version

 http://central.maven.org/maven2/com/google/j2objc/j2objc-annotations/1.1

 If we go to ibiblio, we see the earlier 2016 version
 http://maven.ibiblio.org/maven2/com/google/j2objc/j2objc-annotations/1.1/

 So it does look like bintray pulled from ibiblio and then later from maven
 central. We don't have any assurances bintray wouldn't switch back at some
 point.

 My suggestion at this point, is to dump all uses of bintray. There is
 nothing stopping someone from overriding artifacts, using this as a back
 door. We can point all references directly to maven central and then to
 ibiblio in the (unlikely) situation that central doesn't host the
 artifact.
