How to use for own game?

So I've got modlauncher working in my gradle, but I can't seem to start modlauncher properly.

Exception in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class cpw.mods.cl.ModuleClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader is in module java.base of loader 'bootstrap'; cpw.mods.cl.ModuleClassLoader is in unnamed module of loader 'app')
	at cpw.mods.modlauncher.ModuleLayerHandler.<init>(ModuleLayerHandler.java:52)
	at cpw.mods.modlauncher.Launcher.<init>(Launcher.java:52)
	at cpw.mods.modlauncher.Launcher.main(Launcher.java:77)
	at net.ddns.minersonline.HistorySurvival.Game.start(Game.java:60)
	at net.ddns.minersonline.HistorySurvival.Game.main(Game.java:328)

Here's my game's start method which is called by the main method

    private void start(String[] args) throws IOException, ClassNotFoundException {
        Launcher.main(args); //This is Game.java:60
        ...
    }

This is my full code if anyone needs it
