onPlayerChat not working 1.5.2

I cant Figure out why this plugin will not work.. at all I spent 3 days trying to solve but cant. Any advice?

-Main-

Code:

package me.sooonmitch.Smcf;
 
import java.util.logging.Logger;
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener{
 
    public final Logger logger = Logger.getLogger("Minecraft");
 
    public final ChatListener cl = new ChatListener();
 
    public void onEnabled() {
        logger.info("Enabled Plugin!");
        getServer().getPluginManager().registerEvents(cl, this);
    }
 
    public void onDisable(){
        logger.info("Disabled Plugin!");
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        if (commandLabel.equalsIgnoreCase("banwords")){
            sender.sendMessage("----[Smcf]----");
            sender.sendMessage("Created by Sooon_mitch");
            sender.sendMessage("Vers. 0.1");
            sender.sendMessage("----[Smcf]----");
        }
        return false;
    }
}

-ChatListener-

Code:

package me.sooonmitch.Smcf;
 
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.AsyncPlayerChatEvent;
 
public class ChatListener implements Listener {
 
    @EventHandler
    public void onPlayerChat(AsyncPlayerChatEvent event){
        String message = event.getMessage();
   
        if(message.contains("hello")){
            event.getPlayer().kickPlayer("dark");
        }
    }
}
