Usage:
    $prog [--events-plugin-jar|-t <FILE_PATH>] [--gerrit-war|-g <FILE_PATH>]

    This tool runs the plugin functional tests in a Docker environment built
    from the gerritcodereview/gerrit base Docker image.

    The events plugin JAR and optionally a Gerrit WAR are expected to be in the
    $ARTIFACTS dir;
    however, the --events-plugin-jar and --gerrit-war switches may be used as
    helpers to specify which files to copy there.

    Options:
    --help|-h
    --gerrit-war|-g             path to Gerrit WAR file
    --events-plugin-jar|-e      path to events plugin JAR file
