I assume the reason that your examples print the usage message is 
because you haven't specified the main class (or `-jar` or `-m`).

If you try an example such as `java --dry-run  -p <dir> -m <module>` it 
will load the main class from the initial module and exit at that point 
without invoking the main method.
