我在使用自行打包应用程序的个人项目上遇到了麻烦：
我使用E(fx)clipse创建了我的应用程序，并且我正确生成了build.xml（添加代码以复制我的资源文件夹）。
我需要捆绑包将特定文件提取到特定文件夹（在app文件夹中）所以我可以调用一些executable（android debug bridge代表我。）
当我使用可执行jar文件（安装后在app文件夹中）时，一切正常，但是当我使用已安装的可执行文件时，我无法获取可执行文件的工作目录：
当我“本地”运行时，我可以使用它：System.getProperty("user.dir"));
但是当我运行exe时，没有任何反应，我只是无法得到这个字符串。
更具体地说，这是我的代码：
public void start(Stage stage) {
Circle circ = new Circle(40, 40, 30);
Group root = new Group(circ);
Scene scene = new Scene(root, 400, 300);
stage.setTitle("My JavaFX Application");
stage.setScene(scene);
stage.show();
Stage dialogStage = new Stage();
dialogStage.initModality(Modality.WINDOW_MODAL);
dialogStage.setScene(new Scene(VBoxBuilder.create().
children(new Text("Working Directory = " +
System.getProperty("user.dir"));
"), new Button("Ok.")).
alignment(Pos.CENTER).padding(new Insets(5)).build()));
dialogStage.show();
}
当我使用e(fx)clipse（或可执行jar）运行应用程序时，我得到了工作路径，但是当我使用生成的.exe时，没有任何反应，对话框没有出现
我正在使用JavaFX 2.2和JDK 1.7
感谢您的帮助！
编辑：这是我的build.xml

编辑09/02：我可以显示对话框，但System.getProperty("user.dir")会返回empty string。无法理解为什么。
