I have a module named RCS in my project. While building the RCS module using jenkins, the jar gets created, but it does not contain any class files.

Is this problem because the module name is "RCS" ??
Is "RCS" a keyword and any folder with name "RCS" is ignored during build? Please help.

I cannot change the module name at this stage as development is completed and there are other dependencies.
Pls suggest a way to do the build the module "RCS"
