fun KotlinPlugin.onEnable() {

    }

@Usage("#wrong-usage")
fun testCommand(sender: Sender, arg1: Int, arg2: String, @Optional arg3: String?) {
    sender.sendMessage("test")
    sender.sendMessage("arg1 = $arg1, arg2 = $arg2")
    //if args has 3 argument
    if (arg3 != null) {
        sender.sendMessage(arg3)
