@dmeadows013 yes it will error out only when the vendor/cm repo is updated. Then you'll have to delete the repo in the source tree for it to check out and edit again. Either that or make a fork of it and commit your changes and merge in updated changes from cm's repo on github. You can also submit it to gerrit as others have.
