This plug-in is an add-on for the plug-ins Checkstyle, Dry, FindBugs, PMD, Tasks, and Warnings: the plug-in collects the different analysis results and shows the results in a combined trend graph. Additionally, the plug-in provides health reporting and build stability based on these combined results.
The newest version!
