Question

def main(args: Array[String]) {
    // attach to IRC if irc param is specified
    if(args.contains("--irc")){
        bot = new PircBotX(new Configuration.Builder()
            .setName("GameNotifier")
            .setNickservPassword(args(args.indexOf("--irc") + 1))
            .setServerHostname("IRCSERVER")
            .setServerPort(6667)
            .addListener(new GameIRCListener)
            .buildConfiguration())
        new Thread(new Runnable { def run() { bot.startBot() }}).start()
        Thread.sleep(5000)
        bot.sendRaw().rawLine("JOIN " + ircChannel + " " + args(args.indexOf("--irc") + 2) + "\n")
    } else run = true

如何指定irc参数并在arg中获取--irc？

编辑：

我正在使用SBT编译/打包到.jar。每当我没有--irc运行时我没有问题，但是当使用--irc运行时它会抛出以下内容

Answer 1

你在“--irc？”旁边提供了smth，因为这一行显示你试图获取下一个参数，如果它不存在，它会抛出indexOutOfBoundException。

.setNickservPassword(args(args.indexOf("--irc") + 1))

Scala指定了params
