and here is my main :

Code:

package me.QuecksilberHD.X;
 
import java.util.ArrayList;

import org.bukkit.plugin.java.JavaPlugin;
 
    public class Main extends JavaPlugin {
       
        public ArrayList<String> choosers = new ArrayList<String>();
        public PlayerBlockLeftClickEvent pbl;
        public BlockrespawnEvent bre;
        public Target tar;
        public SignShop sso;
        public CommandExecutre cex;
        public Promotion pro;
        public WithoutLaggs wla;
       
       
        @Override
        public void onEnable() {
 
            pbl = new PlayerBlockLeftClickEvent(this);
            bre = new BlockrespawnEvent(this);
            tar = new Target(this);
            sso = new SignShop(this);
            cex = new CommandExecutre(this);
            pro = new Promotion(this);
            wla = new WithoutLaggs(this);
 
            getCommand("dia").setExecutor(cex);
 
            PluginManager pm = getServer().getPluginManager();
            pm.registerEvents(bre, this);
            pm.registerEvents(pbl, this);
            pm.registerEvents(tar, this);
           
           
            System.out.println("[X] Plugin aktiviert!");
        }
       
        @Override
        public void onDisable()
        {
        System.out.println("[X] Plugin deaktiviert!");
        }
       
        public void onReload()
        {
        System.out.println("[X] Plugin reloaded");
       
        }
    }

 

What is in line 36?

 

Here's a handy guide on how to troubleshoot errors: http://forums.bukkit.org/threads/ho...ubleshoot-your-own-plugins-by-yourself.32457/

 

line 36 is

Code:

getCommand("dia").setExecutor(cex);

But where is the error ?
Bad constructor ?
My Code :

Code:

public class CommandExecutre implements CommandExecutor{
    
    private Main plugin;

    public CommandExecutre(Main plugin) {
        this.plugin = plugin;
    }
    
    
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
         if(cmd.getName().equalsIgnoreCase("dia")){
             if (sender instanceof Player){
                 if (sender.isOp()){
                  //My Code
                 }
             } else {
                 System.out.println("Ein Spieler bist du nicht...");
             }
         }

}    

 

Maybe if you didn't remove the code on //My code we could see the nullpointexception? xD
(I guess)

 

Looks like getCommand("dia") returns null. You should check your plugin.yml, that the command is described correctly.

 

in your onEnable do this...

Code:java

cex = new CommandExecutre(this);

before this

Code:java

getCommand("dia").setExecutor(cex);

That should stop the null pointer.

 

He already is, the issue is most likely that the command that he is attempting to grab ("dia") isn't registered in his plugin.yml and therefore returns null, causing a nullpointer when he calls ".setExecutor" on it.

 

1Rogue didn't read his stuff far enough in

Edit: Fixed my signature to account for times like these...

 

I forget write my command in the plugin.yml
Thank you all
