Bukkit 1.13.2 TabCompleter

Hello, some weeks ago, I started writing a plugin in Java Eclipse. Today I wanted to make the Arguments tabbable so that I can write eg. /info and tab through a list of arguments. I hope you can help me troubleshooting.

package me.themx.info;

public class Info extends JavaPlugin {
   @Override
   public void onEnable() {
      System.out.println("[Info] Plugin erfolgreich aktiviert!");// Start
   }
   @Override
   public void onDisable() {
      System.out.println("[Info] Plugin erfolgreich deaktiviert!");// Stop
   }
 
 
 
   public void registerCommands() {
      getCommand("info").setTabCompleter(new InfoCompleter(this));
    
    
    
   }
   public boolean onCommand(CommandSender sender, Command cmd, String cmdlabel, String[] args) {
      Player p = (Player) sender;
      if (cmd.getName().equalsIgnoreCase("info")) {
         if (args.length == 0) {

package me.themx.info;

import java.util.ArrayList;
import java.util.List;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.command.TabCompleter;

public class InfoCompleter implements TabCompleter{

    public InfoCompleter(Info main) {
    }
   
    @Override
    public List<String> onTabComplete(CommandSender sender, Command cmd, String cmdlabel, String[] args) {
        List<String> arg = new ArrayList<>();
       
        arg.add("verkaufen");
        arg.add("kits");
        arg.add("warps");
        arg.add("team");
        arg.add("farbcodes");
        arg.add("team");
        arg.add("plugin");
       
        if(args.length == 1) {
            return arg;
        }
        else {arg.clear();
        return arg;
        }
    }
}

 

You don't say what exactly is not working out. But I guess if the TabCompleter's onCommand() works similar to JavaPlugin's one then this part of code

Code:

if(args.length == 1) {
    return arg;
}

O
only works if you already wrote one argument in the command line:
/info alreadysomeargument <here will the arg list be tabable>

It would also be cleaner to not create the list ober and over again on every command call. You can have a private list in your InfoCompleter and already fill it in the constructer.

 

Actually, this part of the code

Code:

if(args.length == 1) {
    return arg;
}

only works if there are no arguments.
EX: /info <arg list>
