Thanks for this change @jdai8! I was so confused why zipping was failing for some resource files generated under bazel-out.

To be super clear this argument line {target_path}={c_dir}{res_path} is saying that the file located at {c_dir}{res_path} should be zipped under {target_path} for the resource jar. So moving to {target_path}={f_path} should be more stable, because f.path should always be how input files are located by a bazel action and {target_path} remains the same.

c_dir = c_dir,

This was the only usage of c_dir. Since we don't need it anymore I removed it from the return values as well.
