我使用Java为我的Mac编写了一个文件复制程序。当我从Eclipse中导出可运行的.jar时，一切都很好。所以我将它捆绑为一个.app，然后运行该应用程序。一切看起来都很好，图形用户界面加载，但是当我告诉它从早期的相同位置复制完全相同的文件时，它就在那里。没有文件被复制，但不显示为无响应。Mac Java应用程序以.jar的形式运行，但未能在捆绑为.app时正常运行。应用程序

我想要复制到我桌面上的新文件夹的源文件位于/ Library/Application Support/My Files中。

由于系统将我的Java应用程序视为.app而不是.jar，是否需要向用户请求管理员密码？

当我使用sudo命令从终端运行我的应用程序时，它输出一堆数据。
