Solved Bukkit doesn't register my little Plugin, why?

Here is my Plugin:

Code:java

package me.thrustlp.kangaroo;
 
import java.util.ArrayList;
 
import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.util.Vector;
 
public class Main extends JavaPlugin implements Listener{
 
 
 
 
 
 
 
ArrayList<String> launcher = new ArrayList<String>();   
ArrayList<String> k = new ArrayList<String>();
 
String noperm = "§4No permission! /warp donate";   
 
 
public void onEnable(){
    System.out.println("[Tkits] ON");
    Bukkit.getPluginManager().registerEvents(this, this);
}
 
public void onDisable(){
 
    System.out.println("[Tkits] OFF");
}
 
 
 
 
 
    public boolean onCommand(CommandSender sender, Command cmd, String cmdlabel, String[] args){
        Player p = (Player) sender;
        if(cmd.getName().equalsIgnoreCase("launcher")){
        if(p.hasPermission("tkits.launcher")){
            launcher.add(p.getName());
            k.add(p.getName());
            p.getInventory().clear();
            p.sendMessage("LAUNCHER");
 
 
 
 
        }else{
            p.sendMessage(noperm);
        }
        }
 
 
 
    return false;   
    }
 
    @EventHandler
    public void onMove(PlayerMoveEvent e){
        Player pe = e.getPlayer();
        if(launcher.contains(pe.getName())){
        if(pe.getLocation().getBlock().getType() == Material.SPONGE){
            Vector v = pe.getLocation().getDirection().setY(5.0D);
            pe.setVelocity(v);
 
        }
        }
 
 
    }
 
 
}
 

What's wrong?

EDIT:

I get the following error:

Here is my plugin.yml:

Code:

name: TKITS
version: 0.1
author: ThrustLP
main: me.thrustlp.kangaroo.Main
commands:
    launcher:
          description: Info ueber commands
          usage: /launcher

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Can you show us your plugin.yml?
I think the problem is in there.

 

What about the plugin description? I think its obligatory.

 

Timbals

See post above

 

Nvm, it's not. I think it's your indentation. Do NOT use tabs. Use double space to indent child nodes.

 

AmShaegar

I didn't use any Tabs?

 

No, you used four spaces. I told you to use only two.

 

ThrustLP The stacktrace says that the jar doesn't contain a plugin.yml
Make sure you are including the plugin.yml when exporting and make sure it is at the root of the jar.

It's inside my sources folder but it's not inside my package.

 

ThrustLP It should be in the root of your jar, which is outside of your src folder.
