        # When getting the PR's source branch, Use the commit hash ('github.event.pull_request.head.sha'),
        # instead of the branch name, since 'go get' command does not support all kinds of branch names.
        #
        # Here there also is a limitation that we can't use the 'merge-branch' because it is not visible to 'go get'.
