带有JavaFx 11和JDK 11的Netbeans 9.0

标签: javafx gluon java-11 netbeans-9 javafx-11

我正在尝试在NetBeans 9上运行JavaFX 11 由于JDK 11不再具有JavaFX,因此我无法让NetBeans运行JavaFX项目,它说:"Failed to automatically set-up a JavaFX Platform."

然后我从该网站https://gluonhq.com/products/javafx/下载了javafx11, 在学习了本教程之后,我通常可以通过终端来编译和运行JavaFX类。 我可以添加JavaFX的唯一方法是使用Maven,但是即使该应用程序构建成功,我也无法运行它。

    Error: JavaFX runtime components are missing, and are required to run this application
 Command execution failed.

还有其他方法可以与NetBeans一起运行JavaFX 11吗?还是Eclipse?

也许答案很晚,但是,可能有javafx 11 maven项目+ 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:

public class Main {

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

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:

            <name>YOUR ARTIFACT ID</name>
        </project>
    

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。

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。

由于Java 11启动器检查主类是否扩展javafx.application.Application,因此显示此错误。如果是这种情况,则需要在模块路径上具有javafx.graphics模块。
