[英]How do I launch another app from Java on a Mac
我編寫的在Windows上運行良好的代碼在Mac上無法運行。 我正在呼叫的簡短形式:
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/");
我嘗試運行的軟件沒有與.ema文件建立文件關聯的功能(如果您好奇的話,這是一個游戲)
我的代碼如下所示:
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();
}
}
這將在日志中產生以下內容:

任何幫助或指導,將不勝感激。
嘗試這個..
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:與Ian討論之后。
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/")
您正在嘗試執行“ CM Battle for Normandy.app”,這是一個文件夾(是的,我知道擴展名為.app可能會誤導您)。 您要做的是在該文件夾中找到一個二進制文件,然后執行該文件。 通常在該文件夾中有一個Contents文件夾,在其中是一個MacOS文件夾,並且在該文件夾中應該有一個可執行文件(可能是“ CM Battle for Normandy”)。
您可以在終端機或Finder中找到它。
所以我的問題是要改變:
"/Applications/CM Battle for Normandy/CM Battle for Normandy.app"
至
"/Applications/CM Battle for Normandy/CM Battle for Normandy.app/Contents/MacOS/CM Battle for Normandy"
但這可能略有不同。 它沒有像Windows那樣的擴展名(即.exe或smth)結尾,但這是因為MacOS是Unix類型的系統。
這是從命令行運行的東西嗎? 我看到了一個命令變量,但沒有看到有關其實際作用的上下文。 您可能需要在正在執行的任何命令中添加“ sudo”前綴(假設它在終端中)。 我只是從“權限”錯誤中推斷出這一點。
另外,我看到一個“ getExeFile”。 也許我對此有誤解,但是為什么要在MacOS上尋找.exe? 同樣,我可能只是誤解了這段代碼。 無論如何,我希望這有助於或至少有助於您慢跑。
