Kieron Kierzo which version of warnings-ng is installed in your Jenkins?

BTW: you are mixing health report and quality gates. They are independent of each other.

EDIT: Issue of not having options available in static analysis tool section solved by uninstalling all related plug-ins 1 by 1 and installing next generation plug-in only.

Also found a workaround for Null Pointer Exception. Looks like this tend to happen for newly setup jobs which does not have previous failed jobs. So, you need to make 1st job pass. For this set health gate threshold more than existing warning count. Issue still occurs with latest HPI from Jenkins master - #200

I have similar issue. Ulli Hafner Also Static Analysis Tools select box is empty on freestyle job.

Here is the installed plug-in versions:

mirza zeyrek your NPE is totally different. Please file a new bug report. And please use the released 3.0.3 version (or provide a commit #id) so I can set my workspace to the correct snapshot. The NPE reports that method scanWithTool is on line 492, in the master branch it is at line 576.

Typically, fixing a NPE is quite easy if I have the correct stack trace.

I keep the latest versions (3.0.3) , Jenkins version 2.150.3 (Windows), I also have the old depreciated "Warnings Plug-in" installed too but used in other projects, which is the latest version 5.0.1. It has randomly started working again over the weekend but will report if it starts throwing this error again.

Thanks for your time.
