Plugins depends on the main DMDirc project for some reason.
It shouldn't. That's weird.

This means you can build everything at once, all the plugins, or
the whole parser.

This is a top-level project, containing all of the submodules.
It seems to work with gradle properly.

Hasn't yet got the settings from the other project.
