When someone uses one of my plugins commands but does not enter all of the arguments it returns "An internal error occurred while attempting to perform this command" in game for them and "org.bukkit.command.CommandException: Unhandled exception executing command..." followed by a lot more errors in console. I'm guessing this is a common error when a certain piece of code is not implemented. If you happen to know what code that is then i would be very thankful. I would simply like to msg the player something like "/donate <player> <amount>" so that they can redo the command properly. Thank you.
