[Hawkular-dev] maven release problem

[John Mazzitelli]

OK, so I tried to do a release (of the bus/nest components). After a few hours, I hit a brick wall and can't go further. Someone tell me what's wrong.

First off, you need to fix all your javadoc warnings - because the release plugin will fail if you have any javadoc warnings. So I fixed those. I then did:

   mvn clean install -Prelease

and it finished successfully. I then did:

   mvn clean release:clean release:prepare

and it also finished successfully. I now have a 0.0.2 tag and the git repo looks correct. So I then did:

   mvn release:perform

And it failed, like this:

[INFO] [INFO] Hawkular Nest Distribution ......................... FAILURE [  3.184 s]

I have no idea why this failed when all the other builds were successful. Even Travis finished building successfully! See: http://travis-ci.org/hawkular/hawkular-bus/builds/63241958 ... and FYI: Nexus has a snapshot repo with all of my artifacts except for that last one that failed to build. So Nexus isn't the problem.

How do you debug this? I googled that error message and nothing came up as an obvious fix.

So, after a couple hours, I still have no idea how to do a release successfully, which is odd since I've been told this was supposed to only take me a few seconds to complete :)
