我编写的在 Windows 上运行良好的代码在 Mac 上无法运行。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/");

我尝试运行的软件没有设置与 .ema 文件的文件关联（如果您好奇，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();
    }
}

这会在日志中产生以下内容：

Try this.. 

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/")

UPDATE: After discussing with Ian.. 

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/")

You're trying to execute "CM Battle for Normandy.app" and that's a folder (yeah I know can be misleading with the .app extension). What you want to do is to find a binary in that folder and execute that instead. Usually in that folder there's a Contents folder and in it a MacOS folder and in that folder there should be an executable (probably "CM Battle for Normandy").

You can find it with your terminal or Finder.

So my quess is to change:

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

To

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

But it might be slightly different. It does not have end in an extension like on Windows (i.e. .exe or smth) but that's because MacOS is a Unix type system.

Is this running things from command line? I see a command variable but I don't see any context regarding what it actually is/does. You may need to add a 'sudo' prefix to whatever command that is (assuming it's in terminal). I'm just inferring that from the Permissions error.

Also, I see a 'getExeFile.' Maybe I'm misunderstanding this but why would you be looking for a .exe on MacOS? Again, I could just be misunderstanding this code. Anyway, I hope this helps or at least helps you jog your brain.
