Configuration levels in maven

 In maven configuration control happens on four differ levels: the site level, the group level,
 the project level, and the user level. On the site level you can configure maven for all users

 *
 * The root locator is usually looked up from the plexus container.
 * One notable exception is the computation of the early {@code session.rootDirectory}
 * property which happens very early.  The implementation used in this case
 * will be discovered using the JDK service mechanism.
 *
 * The default implementation will look for a {@code .mvn} child directory

                     * happens, add on class-path or module-path if allowed, or keep patching otherwise.
                     * The latter case (keep patching) is okay if the main module will be defined later.
