我在Windows上编写的代码工作正常无法在Mac上运行。 缩写形式，我呼吁：如何在Mac上从Java启动另一个应用程序
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/");
没有文件关联设置与我尝试运行的软件.ema文件（这是一个游戏，如果你是好奇）
我的代码看起来像这样的：
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();
}
}
这将产生日志中的以下内容：

有趣的是，在这种情况下open有什么作用？ –
@IanLeslie - 'open'是执行应用程序的Mac命令。尝试'打开/应用程序/ CM战斗诺曼底/ CM争夺诺曼底.app --args 2vs2'白色庄园072.ema'从'终端'确认。 – vidit
此外，我编辑了我的答案，在其中添加'--args'，这是将参数传递给应用程序所必需的。 – vidit
