Question

JavaFX无法使用IntelliJ使用。虽然确实可以编译，但是在尝试启动时出现异常。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：

导致此异常所需的代码只有以下内容：

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，则会收到相同的异常。我确实在项目设置中使用了Java 9 jdk。

尝试将Main更改为：

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

JavaFX不适用于IntelliJ（jdk 9）
