JavaFX ProGuard 应用程序在混淆后无法运行

Question

在尝试混淆我的 javaFX 应用程序 4 天但没有成功后，我正在写这个问题...

关于项目：
JDK：阿祖尔 JavaFX 8.42.0.23
构建工具：Maven
Ide：Intelij
ProGuard 版本：6.2.2

问题是什么：
我无法正确混淆我的代码。在将应用程序构建为本机和 fatjar 之后，一切正常。混淆后我有以下错误：

 javafx.fxml.LoadException:

当前的 progard 设置：

此外，我还查看了来自 Whosebug 的建议：
将所有 FXML 文件的名称更新为大写
添加所有类名列表作为 classobfuscationdictionary

其他信息，我有应用程序的预加载器（带有徽标和加载栏的单个 fxml）并且它正在运行。问题是当我尝试加载 main window 的应用程序时，其中 fxml 包含包含标签。

经过 5 天的寻找，我找到了解决方案。

问题是由从 javax 包外部导入 fxml 文件引起的。要解决此问题，我们必须：

选中下面的复选框：

并将导入添加为 "keep"
