[Solved] Ilegal AccessError: tried to access class

Hello,

I have an error with currently code:

Code (Text):

        for (final PacketType packet : packets) {
            ProtocolLibrary.getProtocolManager().addPacketListener(new PacketAdapter(Guardian.instance.getPlugin(),ListenerPriority.NORMAL, packet) {
                @Override
                public void onPacketReceiving(PacketEvent event) {
                    if (event.getPacketType() == packet) {
                        Player player = event.getPlayer();
                        if (player == null || !player.isOnline())
                            return;
                        if (!Guardian.instance.manager.contains(player.getUniqueId())) return;
                        BadBlockPlayer bbp = Guardian.instance.manager.get(player);
                        bbp.lastKeepAlive = System.currentTimeMillis();
                    }
                }
            });
            System.out.println(packet.name() + " packet loaded!");
        }
 

This line causing error is:

Code (Text):

ProtocolLibrary.getProtocolManager().addPacketListener(new PacketAdapter(Guardian.instance.getPlugin(),

Exception is here:
