How to use the gitman.exceptions function in gitman

def _run_command(function, args, kwargs):
    success = False
    exit_message = None
    try:
        log.debug("Running %s command...", getattr(function, '__name__', 'a'))
        success = function(*args, **kwargs)
    except KeyboardInterrupt:
        log.debug("Command canceled")
    except exceptions.UncommittedChanges as exception:
        _show_error(exception)
        exit_message = (
            "Run again with --force/--force-interactive to discard changes "
            "or '--skip-changes' to skip this dependency"
        )
    except exceptions.ScriptFailure as exception:
        _show_error(exception)
        exit_message = "Run again with '--force' to ignore script errors"
    except exceptions.InvalidConfig as exception:
        _show_error(exception)
        exit_message = "Adapt config and run again"
    finally:
        if exit_message:
            common.show(exit_message, color='message')
            common.newline()

    if success:
        log.debug("Command succeeded")
    else:
        log.debug("Command failed")
        sys.exit(1)
