PCT documentation is also in place now: https://github.com/jenkinsci/plugin-compat-tester

What I meant is if the change proposed here is to support the experiment/adoption of the Custom WAR Packager or if there are any other benefits for traditional JTH against core / plugins that has some old problems originating from different dependency handling.

olivergondza In the current state I doubt there will be benefit for traditional flows. "Custom WAR packager" enables JTH testing with Bundled plugins/groovy scripts and offers fixes for some issues there (e.g. resolves conflicts between bundled plugins and test dependencies).

So far I do not see ho these patches could help classic flows which do not bundle plugins or scripts. The proposed patches could be applied to detached plugins, probably.
