Deleting Info from a YamlConfiguration help!

so for some time now i have vigorously been working on a oitq plugin and its all working except for the deleting of arenas, so here is the command that deletes the arena:

Code(CommandExecutor) (open) Code(CommandExecutor) (close)

Code:

if (args[0].equalsIgnoreCase("delete")) {
                if (player.hasPermission("oitq.delete")) {
                    if (args.length < 2) {
                        player.sendMessage(prefix + "Usage: /oitq delete [arenaName]");
                    } else
                        if (ArenaStorage.arenaExists(args[1])) {
                            Main.arenas.getDefaults().set("Arenas." + args[1], null);
                            Main.arenas.getDefaults().set("Arenas." + args[1] + ".Signs.Counter", null);
                            this.plugin.getConfig().getDefaults().set(args[1] + ".Countdown", null);
                            this.plugin.getConfig().getDefaults().set(args[1] + ".MaxPlayers", null);
                            this.plugin.getConfig().getDefaults().set(args[1] + ".KillsToWin", null);
                            this.plugin.getConfig().getDefaults().set(args[1] + ".AutoStartPlayers", null);
                            this.plugin.getConfig().getDefaults().set(args[1] + ".EndTime", null);
                            ArenaProcess arena = new ArenaProcess(args[1]);
                            ArenaStorage.deleteArena(arena);
                            Utils.removeFromList(arena);
                            player.sendMessage(prefix + "You have deleted the Arena " + ChatColor.GOLD + arena.getName());
                            Utils.saveYamls();
                            this.plugin.saveConfig();
                        } else {
                    player.sendMessage(prefix + "That Arena doesn't Exist!");
                }
            } else {
                player.sendMessage(np);
            }
            }

However this isnt removing the arenas!
Here is my onEnable();
if you need any other information please tell me, dont spoon feed me code either unless there is no other way to get the idea to me please.

onEnable() (open) onEnable() (close)

Code:

    public static File playersFile;
    public static FileConfiguration players;
    public static File arenasFile;
    public static FileConfiguration arenas;
 
    @Override
    public void onEnable() {
        //Enable
        this.getServer().getConsoleSender().sendMessage(prefix + "Enabled.");
        //Commands
        getCommand("oitq").setExecutor(new Executor(this));
        //Files
        Main.playersFile = new File(getDataFolder(), "players.yml");
        Main.arenasFile = new File(getDataFolder(), "arenas.yml");
        Main.arenas = new YamlConfiguration();
        Main.players = new YamlConfiguration();
        //Config setups
        Main.arenas.options().copyDefaults(true);
        Main.players.options().copyDefaults(true);
        this.getConfig().options().copyDefaults(true);
        this.saveDefaultConfig();
        getServer().getPluginManager().registerEvents(this.gl, this);
        getServer().getPluginManager().registerEvents(this.sl, this);
        try
        {
          for (String s : Main.arenas.getStringList("Arenas.List"))
          {
            ArenaProcess arena = new ArenaProcess(s);
            ArenaStorage.addArena(arena);
            arena.updateSigns();
          }
        }
        catch (Exception e)
        {
          this.logger.severe("[OITQ] Failed to load arenas!");
        }
        try
        {
          this.m.firstRun();
        }
        catch (Exception localException1) {}
        Utils.loadYamls();
    }
    @Override
    public void onDisable() {
        this.getServer().getConsoleSender().sendMessage(prefix + "Disabled.");
    }
 
}

Any help would be greatly appreciated!

 

You're setting the defaults to null... Set the config keys to null, i.e. Remove all the usages of getDefaults(). E.g.

Code:

Main.arenas.set("Arenas." + args[1], null);

 

@x_Jake_s Well a nice start would be to stop abusing statics.

 

so like this im asuming.

Code:

if (args[0].equalsIgnoreCase("delete")) {
                if (player.hasPermission("oitq.delete")) {
                    if (args.length < 2) {
                        player.sendMessage(prefix + "Usage: /oitq delete [arenaName]");
                    } else
                        if (ArenaStorage.arenaExists(args[1])) {
                            Main.arenas.set("Arenas." + args[1], null);
                            ArenaProcess arena = new ArenaProcess(args[1]);
                            ArenaStorage.deleteArena(arena);
                            Utils.removeFromList(arena);
                            player.sendMessage(prefix + "You have deleted the Arena " + ChatColor.GOLD + arena.getName());
                            Utils.saveYamls();
                            this.plugin.saveConfig();
                        } else {
                    player.sendMessage(prefix + "That Arena doesn't Exist!");
                }
            } else {
                player.sendMessage(np);
            }
            }

When i use this code, it sends the delete message but nothing happens to the actual arena inside my config files.

 

Still need help please <Bump>

 

If the arena is also in your config.yml, you've gotta do: this.plugin.getConfig().set("Arenas." + args[1], null);

Does Utils.saveYamls(); actually save Main.arenas config? That looks like yours should work.

Wait a second... Don't tell me "arenas" config is the exact same file as the plugin's config file?
