       }
     }

package me.coding.minigame;

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.entity.Player;

public class ArenaCreator implements CommandExecutor {
   private Minigame plugin;
   
   public ArenaCreator(Minigame minigame) {
     this.plugin = plugin;
     YamlConfiguration config = (YamlConfiguration) Minigame.plugin.getConfig();
   }
   
   public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
     Player p = (Player) sender;
     String m = ChatColor.GREEN + "[" + ChatColor.AQUA + "Minigame" + ChatColor.GREEN + "] " + ChatColor.WHITE;
     FileConfiguration config = getConfig();
     
     if(cmd.getName().equalsIgnoreCase("fmakearena")) {
       if (p.hasPermission("f.makearena")) {
         config.set("fsfd", p.getName());
       } else {
         p.sendMessage(m);
       }
     }
     return false;
   }

   private FileConfiguration getConfig() {
     return null;
   }
}

Plugin.yml:

Code:

name: Minigame
version: 1.0
main: me.coding.minigame.Minigame
commands:
  FMakeArena:
  description: Make an arena.
  permission: f.makearena
  FSaveConfig:
  description: Save and reload the config.
  permission: f.reload

 

you need to make 4 spaces on the description and permission in the plugin.yml

 

Locked, duplicate.
