Solved PacketPlayInClient/CraftPlayer

Until today, I've used the spigot jar to code and compile my plugins. Yesterday I started using the api, and today I removed the jar. The only error I've received upon doing this is not being able to use PacketPlayInClient and CraftPlayer to perform a respawn command.
Here's the code, though it's not very necessary, as the files don't exist.

Code:

            final Player player = e.getEntity();
            Bukkit.getScheduler().runTask(plugin, new Runnable(){
                public void run()
                {
                    PacketPlayInClientCommand packet = new PacketPlayInClientCommand(EnumClientCommand.PERFORM_RESPAWN);
                    ((CraftPlayer)player).getHandle().playerConnection.a(packet);
                }
            });

I'd just like an answer as to whether I should go back to using the spigot.jar, or if there's another way to use CraftPlayer and PacketPlayInClient.

 

@elian1203 You must use the CraftBukkit/Spigot server jar file to use packets.

 

@BrickBoy55 Okay thanks
