JavaFX不适用于IntelliJ(jdk 9) [英] JavaFX does not work with IntelliJ (jdk 9)

问题描述

JavaFX无法使用IntelliJ使用.虽然确实可以编译，但是在尝试启动时会出现异常.我在这里发现了类似的问题，但似乎都无法解决我的问题.我得到的异常如下:

JavaFX is not working for me using IntelliJ. While it does compile, I get an Exception when trying to launch. I've found similar issues here, none of which seemed to hold an answer to my problem. The Exception I get is the following:

导致此异常的代码仅是以下内容:

The code required to cause this Exception is only the following:

import javafx.application.Application;
import javafx.stage.Stage;

public class Test extends Application
{

    @Override
    public void start(Stage primaryStage) throws Exception
    {

    }

    public static void main(String... args)
    {
        Application.launch(Test.class, args);
    }
}

此外，使用Eclipse在旧的Eclipse项目中运行代码的工作正常.但是，如果我将代码复制到IntelliJ，则会收到相同的Exception. 我确实在项目设置中使用了Java 9 jdk.

Furthermore, running code form old Eclipse projects using Eclipse is working. However, if I copy the code over to IntelliJ, I get the same Exception. I do use the java 9 jdk in the project settings.

推荐答案

尝试将Main更改为:

Try changing your Main to:

public static void main(String[] args)
{
    launch(args);
}
