Java - 预期为“”但发现未知令牌
当我尝试从我的 java 应用程序执行 applescript 时，我收到此错误。代码如下：
String script = "tell application \"Terminal\" to do shell script \"/System/Library/CoreServices/Menu\\ Extras/user.menu/Contents/Resources/CGSession -suspend\" ";
ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine engine = mgr.getEngineByName("AppleScript");
engine.eval(script);
我收到以下错误：
Exception in thread "main" javax.script.ScriptException: Expected “"” but found unknown token.
at apple.applescript.AppleScriptEngine.evalScript(Native Method)
at apple.applescript.AppleScriptEngine.eval(AppleScriptEngine.java:342)
at apple.applescript.AppleScriptEngine.eval(AppleScriptEngine.java:313)
at myTestApp.Main.main(Main.java:25)
感谢您的考虑。

基于经验的猜测......也许路径名中的转义空格是你的表演障碍。
尝试从路径没有空格的位置调用脚本，或者尝试“双重转义”转义的空格，如下所示：
奇怪错误的常见原因是路径名中的空格。所以这是我的第一个猜测，这会给你的脚本带来麻烦。然后我想起有时我们必须“转义转义的反斜杠”。 本文没有解释为什么它能准确解决你的问题，但它显示可能需要多少个反斜杠......
A guess based on experience... Maybe the escaped space in the pathname is your show stopper.
Try to call a script from a location where the path has no spaces or try to 'double-escape' the escaped space, like so:
A common reason for strange errors are those whitespaces in pathnames. So it was my first guess, that this causes trouble in your script. Then I remembered that sometimes we have to 'escape escaped backslashes'. This article doesn't explain, why it solved exactly your problem, but it shows how many backslashes may be needed...
您需要“双重转义”路径中的空格：
You need to 'double-escape' the space in the path:
