Greetings.
I have written a notification plugin that sends events to Amazon Kinesis.
Unfortunately, if I run this plugin in a job using Maven 3.0.3 the plugin
works but the job crashes at the end:

I searched around and found several bug reports on similar issues,
indicating that fixes had been submitted, so I tried with Maven 3.2.2 and
everything works fine.
What I want to do is have my plugin detect which version of Maven is being
used and disable itself if an unsafe version has been selected.
I've not had any luck figuring out how to do that:
- I tried extending MavenReporter, so I could get a MavenBiuldProxy in
preBuild() or preExecute(), and call
getMavenBuildInformation().getVersion(), but neither would ever fire. Not
sure this is the right version to check anyway.
- I tried using Jenkins.getInstance().getPlugin("maven-plugin") to work
my way towards calling hudson.MavenInformation.getVersion(), but couldn't
figure out how to get a useful object to make a call on. Not sure this is
the right version to check anyway.
Any advice would be much appreciated.
Thanks,
- Jeff
