java - 如何在 Mac 上从 Java 启动另一个应用程序

Question

我编写的在 Windows 上运行良好的代码在 Mac 上无法运行。我调用的简短形式:

Runtime.getRuntime().exec (String ["/Applications/CM Battle for Normandy/CM Battle for Normandy.app" "2vs2 White Manor 072.ema"], null, "/Applications/CM Battle for Normandy/");

我尝试运行的软件没有与 .ema 文件建立文件关联(如果你好奇的话，这是一个游戏)

我的代码如下所示:

    private void launchGameProgram (PBEMGame selectedGame) {
    if (selectedGame == null)
        return; // no work to do

    InstalledProgram program = selectedGame.playedWith ();
    if (program == null)
        return; // no work to do

    try {
        Vector<String> command = new Vector<String> ();
        command.add (program.getExeFile ().getAbsolutePath ());
        if (selectedGame.getLastTurn () != null  &&  selectedGame.getLastTurn ().getTurnFile () != null)  {
            //  Add the turn file name to the command
            command.add (selectedGame.getLastTurn ().getTurnFile ().getName ());
        }
        GUIApplicationPolicy.getLog ().log ("WTII testing: About to launch: " + command.toString () + " from: " + program.getExeFile ().getParentFile ());
        Runtime.getRuntime ().exec (command.toArray (new String[command.size ()]), null, program.getExeFile ().getParentFile ());
    } catch (IOException exception) {
        GUIApplicationPolicy.getLog ().log (exception);
        exception.printStackTrace();
    }
}

这会在日志中生成以下内容:

试试这个..

Runtime.getRuntime().exec (String ["open /Applications/CM Battle for Normandy/CM Battle for Normandy.app" "--args" "2vs2 White Manor 072.ema"], null, "/Applications/CM Battle for Normandy/")

更新:与 Ian 讨论后..

Runtime.getRuntime().exec (String ["open" "/Applications/CM Battle for Normandy/CM Battle for Normandy.app" "--args" "2vs2 White Manor 072.ema"], null, "/Applications/CM Battle for Normandy/")
