[forge-dev] [forge-users] Get a list of all classes extending a specific class

[Rudy De Busscher]

Hi Lincoln,

created today some kind of prototype for getting all class information,
like class name, super type and interfaces of the java source files in the
project.

It handles nested classes correctly

See this commit
https://github.com/rdebusscher/forge-plugin-deltaspike/commit/ffa511c8ba87282b5ceca7bd1c37a5389dc4d64d

With this, I can find all classes that implement ProjectStage of DeltaSpike
what we need to have proper value/token completion.

regards
Rudy
