使用Ant

Question

我有疑问。如何使用Ant为JavaFX应用程序制作胖jar？我知道在互联网上有一些问题，但它涉及Java应用程序，而不是JavaFX应用程序。我认为这是不同的，因为我试图遵循这个教程，它适用于Java应用程序，但在尝试运行应用程序后使用fxml文件的JavaFX应用程序中，它返回NullPointerException：location是必需的（是的，我尝试了修改程序路径到fxml文件，并使用ClassLoader，它没有帮助）。我也尝试使用Ant的One Jar插件，效果相同。

我有以下build.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

如何修改它，制作包含所有依赖项的胖jar？我知道在Maven中更容易制作，但我想知道，这在Ant中是否可行。 此致
