import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;

    @Override
    public void onEnable(){
        getLogger().info(">> AntiJump has been Enabled <<");
        getServer().getPluginManager().registerEvents(new AntiJump(), this);
      
    }
  
  
    @Override
    public void onDisable(){
        getLogger().info(">> AntiJump has been Disabled <<");
      
    }
  
  
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
      
        Player p = (Player)sender;
      
        if(cmd.getName().equalsIgnoreCase("antijump version")){
            if(!p.hasPermission("antijump.admin")){
                p.sendMessage(ChatColor.DARK_RED + "Je hebt hier geen permissie voor!");
            }
          
            p.sendMessage(ChatColor.DARK_GREEN + "AntiJump" + ChatColor.GREEN + "Version" + ChatColor.DARK_RED + "1.0");
        }
        return true;
    }

}

AntiJump class

Code:

package me.YourPalJake;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;

public class AntiJump implements Listener{
  
    @EventHandler
    public void onPlayerJoinEvent(PlayerJoinEvent e){
        Player p = (Player)e;
        if(!p.hasPermission("antijump.admin")){
            p.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 1000000, 127));
           
        }
    }
  

}

NOTE: I have some dutch string because my server is dutch but that is not where the error lies on.
Please help me.
