I think the fix is switching from CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES to SNAKE_CASE:

Thanks for confirming. Would you like to submit the pull request to fix it? You have an environment where you can test it more rapidly than I can configure a test environment.

I filed a Pull request - let me know how I can easily test it - i have no clue how to do so (how would I get the fixed plugin on my jenkins ?)

I've uploaded a zip file of the plugin build. Download it to your local computer, expand the zip file, then use the "Advanced" section of the Jenkins plugin manager page to upload the gitlab-plugin.hpi file. Restart your Jenkins controller and you should see the new SNAPSHOT version displayed in the plugin manager list of installed plugins.
