Cleaning Up Buildspaces
The rwclean Java utility cleans a buildspace by deleting files created during the build process. Deleting build artifacts — such as buildspecs, object files, makefiles, build results, and other files associated with a buildspec — can be done manually; however, you may not detect all the files that need to be deleted to ensure a clean buildspace. Using rwclean ensures that files are removed from your buildspace, coherently and completely, according to your command-line arguments.
