Prevent bukkit from showing no permissions msg?

In a current project of mine i have made a bukkit command go off when a player does an action how can i prevent the "No you cannot do that. if you believe this is an error let the Adminstrator know" not go off?

 

Edit: Irrelevant Message

 

Ok, want proof? I made a whitelisting command that allows players to whitelist themselves only. Not others. Currently im testing my plugin and when i use /wl it throws the no permissions msg plus my messages. I need to find a way to stop bukkit from throwing that no permissions msg.

Code:

package us.topgear93.trialplay.commands;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

import us.topgear93.trialplay.TrialPlay;

public class wl implements CommandExecutor{
    public TrialPlay plugin;
    public wl(TrialPlay plugin){
        this.plugin = plugin;
    }
    @Override
    public boolean onCommand(final CommandSender sender, Command cmd, String label, String[] args) {
        Player player = null;
        if (sender instanceof Player) {
            player = (Player) sender;
            if(label.equalsIgnoreCase("wl")){
                //                        if (TrialPlay.permission.has(sender, "TrialPlay.self.whitelist") || sender.isOp()){
                if(player.isWhitelisted()){
                    player.sendMessage(ChatColor.DARK_BLUE + "[" + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.title") + ChatColor.DARK_BLUE + "]-" + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.wl.already"));
                    return false;
                }
                player.performCommand("whitelist add " + sender.getName());
                player.sendMessage(ChatColor.DARK_BLUE + "[" + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.title") + ChatColor.DARK_BLUE + "]-" + ChatColor.GOLD + sender.getName() + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.wl.added1"));
                player.sendMessage(ChatColor.DARK_BLUE + "[" + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.title") + ChatColor.DARK_BLUE + "]-" + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.wl.added2"));
                Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable(){
                    @Override
                    public void run() {
                        ((Player) sender).kickPlayer(plugin.getConfig().getString("TrialPlay.timer.kickmsg"));                                    
                    }
                }, plugin.getConfig().getLong("TrialPlay.timer.wl"));
                return true;
            }else{
                player.sendMessage(ChatColor.DARK_BLUE + "[" + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.title") + ChatColor.DARK_BLUE + "]-" + ChatColor.DARK_RED + plugin.getConfig().getString("TrialPlay.noperm.wl"));
                return false;
            }
        }
        return false;
    }
}

 

Have you added your command to the plugin.yml file?

 

yep

Code:

name: TrialPlay
main: us.topgear93.trialplay.TrialPlay
version: 0.0.1
depend: [Vault]
commands:
  tp:
      description: version check and config reload
  wl:
      description: whitelist
  trial:
      description: player trial cmd

 

AH! I assume you're displaying the no permission message yourself? With the line:

Code:

player.sendMessage(ChatColor.DARK_BLUE + "[" + ChatColor.WHITE + plugin.getConfig().getString("TrialPlay.title") + ChatColor.DARK_BLUE + "]-" + ChatColor.DARK_RED + plugin.getConfig().getString("TrialPlay.noperm.wl"));

Am I right? If so, change your return statement immediately after that to return true. Anytime you return false, Bukkit will display the No perms message, regardless of what your plugin did before the method returned.

 

the no permissions msg in the config equals "TrialPlay.noperm.wl", "No permissions to whitelist yourself!".

im getting this though.

 

Perhaps it's caused by your attempt to force the player to execute the default whitelist command? If they're not Op, they won't be able to use it, and you'll get that error. If you wanna run it without giving the player Op status, use this:

Code:Java

 
Bukkit.getServer().dispatchCommand(Bukkit.getServer().getConsoleSender(), "whitelist add " + sender.getName());
 

That will execute the command as if it was run from the default console.

 

wow didn't realize there was a shortcut like that. thanks for the help. I did a quick hack job to fix my small problem with temporarily adding the permissions to use the whitelist and then remove it. Your idea is much simpler and safer.

 

Glad to hear I could help
