    @TheDaann Your gamemode class is 1. Not a plugin, 2. Not a listener, 3. Nor does it has any events.

    Start by figuring out what your main class is. Because I don't think that it is the posted one.
    So no onEnable for that one.
    It needs to implements Listener if it needs to handle events.

        Inv = Bukkit.createInventory(null, 27, ChatColor.YELLOW + "Potgrond Gamemode");
    }
   
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(cmd.getName().equalsIgnoreCase("gm")){
            Player p = (Player) sender;

    @TheDaann Does still not implement Listener
    You still have an onEnable, that only works for the main class.
    Give it a constructor.

    @timtower
    I'm not the best Java Developer yet, so don't understand everything. This is not my main class, but a command. Can't say what to add? Or remove it if necessary.

    I know.
    And I won't change your code.
    It is your code.
    Add a constructor.
