    # Get GitSCM status. The purpose of this function is to return the status of the given directory
    #
    # return values:
    #  - error: The SCM is in a error state. Use this if git returned a error code.
    #  - dirty: SCM is dirty. Could be: modified files, switched to another branch/tag/commit/repo, unpushed commits.
    #  - clean: Same branch/tag/commit as specified in the recipe and no local changes.
    #  - empty: Directory is not existing.
    #
    # This function is called when build with --clean-checkout. 'error' and 'dirty' SCMs are moved to attic,
    # while empty and clean directories are not.
