 *   <li>{@link org.apache.maven.cling.invoker.mvnup.goals.Check} - Analyzes projects and reports needed upgrades</li>
 *   <li>{@link org.apache.maven.cling.invoker.mvnup.goals.Apply} - Applies upgrades to project files</li>
 *   <li>{@link org.apache.maven.cling.invoker.mvnup.goals.Help} - Displays usage information</li>
 * </ul>

     *
     * Will block until the server returns a set of changes that match the given filter. The file will be automatically
     * opened if it is not and should be closed with {@link #close()} when no longer
     * needed.
     *
     * Closing the context should cancel a pending notify request, but that does not seem to work reliable in all
     * implementations.

Not all live services have stubs, but can be added as needed.
