我正在使用 Netbeans 8.2，并且正在构建一个简单的 FXML 项目。

从头开始和新的 JavaFX FXML 应用程序，清理和构建工作正常，从 /Dist/ 文件夹启动示例文件工作完美。

然而，

我将 JFoenix 库和任何 JFoenix 元素添加到 FXML 的那一刻，它在编译后将不再启动，发出以下内容。

Exception running application javafxapplication3.JavaFXApplication3

但是，在 NetBeans IDE 中启动可以完美运行。

这里发生了什么？我可以看到 LIB 已正确添加到 /dist/ 文件夹中。

@james_d，注意到我在桌面上运行 java 9，但在 IDE 上运行 java 8。

这解释了我的问题。
