Null pointer exception GitlabMergeRequestWrapper.java:89

Hi,

We can not run this plugin for more than one instance project at our server. At crontab the log informs:

Dec 04, 2014 2:55:04 PM hudson.triggers.Trigger checkTriggers

Is this a bug? Please, what we could do to fix it?

Thanks in advance

I got exact the same problem when there was a merge request that had it's branch deleted already (manual merge and not closed merge request at gitlab).
I think merge requests that for whatever reason doesn't contain any commits should be skipped by the plugin.

I've noticed that current version skips MRs without commits, next release should fix it.

I am also having the same problem. Can it be a configuration issue?

What is the version of GitLabs and the Jenkins Plugin for GitLabs-merge-request-builder?
