Looks like incompatible Versions of plugin and jenkins – Jens

Sounds like an out-of-date plugin/Jenkins install.

I would recommend updating Jenkins if you're on an older version (I'm currently running 2.121.2).

After Jenkins is updated, try updating all of your plugins as well.

From the main Jenkins page, click "Manage Jenkins" and then "Manage Plugins" or just navigate to: http://yourjenkins.install/pluginManager/.

Scroll to the bottom of the page, click the link "All" near the word Select. Then click the big blue Update button.

This will probably resolve the issue, if not, you've got a bigger issue.
