    You have to show us your main class, ServerCore. Since it's where the errors are.

    XxZHALO13Xx Your casting sender to player I am assuming in this format Player player = (Player) sender; however you never check if the send is indeed a player.

    It's a simple error you didn't extend Java Plugin well at least in the code you showed us you didn't. Unless this isn't your main class

    From the error, I believe that he is sending the command from console, but since he is casting the sender to player, then this would cause an error. Also, I thought that if they didn't extend JavaPlugin the plugin wouldn't load.

    In the end, extend JavaPlugin, and send the command as a player.
