也许是一个较晚的答案，但是，可能有javafx 11 maven项目+ NetBeans 9.

Maybe a late answer, but, it is possible to have javafx 11 maven project + NetBeans 9.

1. Maven不喜欢在主要方面扩展Application.您应该使用两个类:

Main.java:

Main.java:

public class Main {

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

MainApp.java:

MainApp.java:

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class MainApp extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("Hello World!");
        String a;
        a = new String("test");
        Button btn = new Button();
        btn.setText("Say 'Hello World'");
        btn.setOnAction(new EventHandler<ActionEvent>() {

            @Override
            public void handle(ActionEvent event) {
                System.out.println("Hello World!");
            }
        });

        StackPane root = new StackPane();
        root.getChildren().add(btn);
        primaryStage.setScene(new Scene(root, 300, 250));
        primaryStage.show();
    }
}

1. 您的pom.xml应该如下所示:

1. Your pom.xml should look like this:

    <?xml version="1.0" encoding="UTF-8"?>

这将在netbeans中正常工作. 基本上，您需要做的是启动新的maven项目，完成项目设置后，只需替换pom.xml.

This will work in netbeans without any issues. Basically, what you need to do is start new maven project and after you finish setting project just replace pom.xml.

这样，您的代码将从IDE运行，并且可以正确编译，因此您可以使用java --jar从命令行运行它.另外，您将能够运行NB调试器.

This way your code will run from IDE, and will compile correctly so that you can run it from command line with java --jar. Also, you will be able to run NB debugger.
