Solved Help with command aliases

Discussion in 'Spigot Plugin Development' started by Cerus, Sep 24, 2018.

  1. Hey,
    I know that I can set aliases in my plugin.yml, but is there a way to set them in the code? I know the method Command#setAliases, but it doesnt work for me. I dont get any errors.
    Code (Java):
    PluginCommand command = getCommand("teammanager");
            command.setExecutor(new TeamManagerCommand(storage));
    The string list exists in my config.
    Any help?
  2. I'm not sure if I remember right but I think the alias must be set prior to registering your command otherwise you have to manually register it in the command map which can result in unexpected issues.

  3. But how can I set the aliases before registering?
  4. This is what Towny uses:

    Code (Text):

        private void registerSpecialCommands() {
            List<Command> commands = new ArrayList<>();
            commands.add(new AcceptCommand(TownySettings.getAcceptCommand()));
            commands.add(new DenyCommand(TownySettings.getDenyCommand()));
            commands.add(new ConfirmCommand(TownySettings.getConfirmCommand()));
            commands.add(new CancelCommand(TownySettings.getCancelCommand()));
            try {
                final Field bukkitCommandMap = Bukkit.getServer().getClass().getDeclaredField("commandMap");

                CommandMap commandMap = (CommandMap) bukkitCommandMap.get(Bukkit.getServer());

                commandMap.registerAll("towny", commands);
            } catch (NoSuchFieldException | IllegalAccessException e) {
    You will need to make an object that extends BukkitCommand it should look similar to this, obviously the code in execute is merely an example.
    Code (Text):
    public class AcceptCommand extends BukkitCommand {
        public AcceptCommand(String name) {
            this.description = "Accept command for Towny";
            this.usageMessage = "/" + name + " <Town>";

        public boolean execute(CommandSender commandSender, String s, String[] strings) {
            if (commandSender instanceof Player) {
                InviteCommand.parseAccept((Player) commandSender, strings);
                return true;
            } else {
                return true;

  5. Ah, so I have to use the command map. Alright, I'll take a look at it and close this thread when I come to a conclusion. Thank you all!
    Edit: Solved. :)
