我正在使用 JDK 11.0.1 和来自 OpenJFX 的 JavaFX 11 运行 IntelliJ IDEA Ultimate 2018.2.5。我知道这是一个常见错误，我尝试了很多建议的修复方法，但没有任何效果。
无论我尝试运行哪个 JavaFX 项目，我都会收到错误:
Error: JavaFX runtime components are missing, and are required to run this application
如果我将以下内容添加到 VM 选项中
--module-path="C:\Program Files\Java\javafx-sdk-11\lib" --add-modules=javafx.controls
我收到这些错误:

Exception running application sample.Main
我试过重新安装，但没有成功。我也尝试过改变
getClass().getResource(...) 到 getClass().getClassLoader().getResource(...) 或类似 Parent root = FXMLLoader .load(getClass().getResource("/sample.fxml")); 但仍然不起作用。
