I would like to integrate SourceMonitor into my Jenkins CI-system. Since there is no SourceMonitor plugin how can i make the results of SourceMonitor visible on my Jenkins Serve
There is an open issue associated with the Violations plugin.
You can vote up for the implementation of this issue: https://issues.jenkins-ci.org/browse/JENKINS-5741
You only realistically have the following options:
I guess you're out of luck. You could take a look at similar plugins (probably FindBugs, PMD, Checkstyle plugins should be comparable) and write a plugin yourself.
You could also give a try to post to the Jenkins user mailing list, maybe someone there can help you.
Don't know what kind of output SourceMonitor produces, but if it produces HTML Reports, there is an HTML Publish Plugin, which would let you link and display those results in your job. Not as integrated as a real plugin would be, but perhaps that would be enough for you.
