尝试在intellij jre11上运行javafx程序[重复]

Question

我已经安装了intellij，并且试图打开一个新的javafx，但是我无法运行它（即使是基本的默认的，应该只是打开一个简单的窗口）。我使用的是JDK11（我必须），所以我下载了javafx，就像本文中所说的那样：

错误：JavaFX运行时组件丢失，而使用JDK 11运行此应用程序需要JavaFX运行时组件

但我得到了这个错误

"C:\Program Files\Java\jdk-11.0.1\bin\java.exe" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA
2018.2.5\lib\idea_rt.jar=59874:C:\Program Files\JetBrains\IntelliJ IDEA 2018.2.5\bin" -Dfile.encoding=UTF-8 -classpath "C:\Users\itzik\IdeaProjects\untitled3\out\production\untitled3;C:\Program Files\Java\javafx-sdk-11\lib\src.zip;C:\Program Files\Java\javafx-sdk-11\lib\javafx-swt.jar;C:\Program Files\Java\javafx-sdk-11\lib\javafx.web.jar;C:\Program Files\Java\javafx-sdk-11\lib\javafx.base.jar;C:\Program Files\Java\javafx-sdk-11\lib\javafx.fxml.jar;C:\Program Files\Java\javafx-sdk-11\lib\javafx.media.jar;C:\Program Files\Java\javafx-sdk-11\lib\javafx.swing.jar;C:\Program Files\Java\javafx-sdk-11\lib\javafx.controls.jar;C:\Program Files\Java\javafx-sdk-11\lib\javafx.graphics.jar" sample.Main


Error: JavaFX runtime components are missing, and are required to run this application

如果我试着在溶液中做这一行

然后在run->edit configurations->VM Options中，输入:--module-path=“c:\program files\java\javafx-sdk-11\lib”--add-modules=javafx.controls

错误更改到：

"C:\Program Files\Java\jdk-11.0.1\bin\java.exe" "--module-path=C:\Program Files\Java\javafx-sdk-11\lib"
--add-modules=javafx.controls "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA

常规java程序与hello world做工作，只是java fx做问题...

如果在Java11中使用JavaFX，则需要添加JavaFX jar文件。
