I've made a library/utility mod that all my other mods depend on because I don't like having so much duplicate code. Now I created a sort of 'Dummy' mod class (a class annotated with @Mod) so that I can still hook into the @EventHandler events, as well as use the 'dependencies' functionality of @Mod.

 

I don't really think it's necessary for this dummy mod to be shown in the 'Mods' screen (from the game menu). What would be the best way to approach this?

Alright, I've managed to do it, but it sure feels like a hack around something that could be done more elegantly.

@SubscribeEvent
public void onGuiOpen(GuiOpenEvent event)
{
    if(event.gui instanceof GuiModList)
    {
        ModContainer container = Loader.instance().getIndexedModList().get(UtilModDummy.MOD_ID);
        ((List<ModContainer>)ReflectionHelper.getPrivateValue(GuiModList.class, (GuiModList)event.gui, "mods")).remove(container);
    }
}
