Question

我写的代码在Windows上运行良好的代码不适用于Mac。我打电话的简短形式：

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/");

我正在尝试运行的软件没有与.ema文件建立文件关联（如果你很好奇，那就是游戏）

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：

Answer 1

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：与伊恩讨论后。

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/")

Answer 2

你正在尝试执行“CM Battle for Normandy.app”，这是一个文件夹（是的，我知道可能会误导.app扩展名）。你想要做的是在该文件夹中找到一个二进制文件并执行它。通常在该文件夹中有一个Contents文件夹，其中有一个MacOS文件夹，在该文件夹中应该有一个可执行文件（可能是“诺曼底的CM战斗”）。

您可以使用终端或Finder找到它。

所以我的意思是改变：

"/Applications/CM Battle for Normandy/CM Battle for Normandy.app"

要

"/Applications/CM Battle for Normandy/CM Battle for Normandy.app/Contents/MacOS/CM Battle for Normandy"

但可能略有不同。它没有像Windows上那样的扩展（即.exe或smth），但那是因为MacOS是一个Unix类型的系统。

Answer 3

这是从命令行运行吗？我看到一个命令变量，但我没有看到任何关于它实际是什么/做什么的背景。您可能需要在任何命令中添加“sudo”前缀（假设它在终端中）。我只是从权限错误中推断出来。

另外，我看到'getExeFile'。也许我误解了这个，但你为什么要在MacOS上寻找.exe？再一次，我可能只是误解了这段代码。无论如何，我希望这有助于或至少帮助你慢跑你的大脑。
