Привет, я только вчера начал изучать ProtocolLib, я вроде всё как в документации сделал но не работает

Код: 
package me.FortiBrine.TestPlugin;

import com.comphenix.protocol.PacketType;
import com.comphenix.protocol.ProtocolLibrary;
import com.comphenix.protocol.ProtocolManager;
import com.comphenix.protocol.events.ListenerPriority;
import com.comphenix.protocol.events.PacketAdapter;
import com.comphenix.protocol.events.PacketContainer;
import com.comphenix.protocol.events.PacketEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin {

    private Main instance;

    public Main getInstance() {
        return instance;
    }

    @Override
    public void onEnable() {
        instance = this;

        ProtocolManager protocolManager = ProtocolLibrary.getProtocolManager();
        protocolManager.addPacketListener(new PacketAdapter(this, ListenerPriority.NORMAL, PacketType.Play.Client.CHAT) {
            @Override
            public void onPacketReceiving(PacketEvent event) {
                PacketContainer packet = event.getPacket();
                event.getPlayer().sendMessage(packet.getStrings().read(0));
            }
        });
    }

}
