I created a custom parser as seen in the attached screenshot below. It is not particularly useful, but it was a simple case to test. When adding a new tool to the post-build task I do not see my custom parser in the list. As far as I can tell from the documentation I have done the necessary steps.

I have restarted Jenkins. The one thing that stands out in the documentation is "Once your Groovy parser has been registered you can use it...". Is there a special register step that is missing from the documentation or is this a bug.
