In the plist package classes generated by JavaCC are used to parse specific configuration files. Currently these files are stored in SVN like regular source files. This does not conform to best practices, is confusing, and requires a special treatment in the configuration of tools like checkstyle or findbugs.
It would be better to let these files be generated during the build process by the maven JavaCC plug-in. A working configuration can kindly be borrowed from the OGNL component. The additional generation step should not slow down the build significantly.
