Hi! I just realized that the result with `--add-modules ALL-MODULE-PATH` is _not_ the same as without. I accidentally tried it when the class files were already present in `classes`, which led to no compilation and hence no message.
With `classes` being empty I get this instead: error: --add-modules ALL-MODULE-PATH can only be used when compiling the unnamed module error: --add-modules ALL-MODULE-PATH can only be used when compiling the unnamed module error: --add-modules ALL-MODULE-PATH can only be used when compiling the unnamed module error: cannot access module-info cannot resolve modules error: cannot access module-info cannot resolve modules 5 errors It seems a little weird that a faulty command does not create an error but that may be be design because no compilation has to happen. so long ...
