Subject changed from caffeine in version 2.8.6 breaks all rudder to Missing base class of plugins breaks `reflections` with caffeine version 2.8.2

OK, so it has nothing to do with caffeine, and for now I don't understand why changing its version triggered the problem.

But looking around in the internet, I found that ticket: https://github.com/victools/jsonschema-generator/issues/102#issuecomment-640905754

And yes, adding the package where RudderPluginModule is defined in reflections package to scan DID solved the issue.

And I think I don't want to dig it further. Classpath are complicated; reflection is complicated; both are brittle. It works, fine.
