我正在尝试一起使用java 11和javaFX(我是java 11的新手)并遵循this tutorial但我不断收到模块 javafx.controls 不存在的错误，即使它存在于 PATH_TO_FX 变量中指定的路径中。项目的所有属性均按照教程进行设置。

以下是该项目的虚拟机选项:

--module-path %PATH_TO_FX%


--add-modules javafx.controls,javafx.fxml

<小时/>

变量 PATH_TO_FX 的值为 C:\javafx-sdk-11.0.2\lib 这是 javafx 库的文件路径

已添加到环境变量编辑器中

可能的修复方法之一是添加 JavaFX 11 库:

Properties -> Libraries -> Run -> Modulepath
