如何使用Maven构建可运行的JavaFX应用程序？

Question

我是JavaFX新手。我使用Maven创建了一个Hello World项目。当我在Eclipse中运行时，它工作得很好。

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

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

当我试图使用build.fxbuild构建应用程序时，我得到了这个错误。

现在有一个用于JavaFX的maven插件：

https://github.com/zonski/javafx-maven-plugin

<plugin>
    <groupId>com.zenjava</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>1.1</version>
    <executions>
        <execution>

    </executions>
    <configuration>
        <mainClass>[put your application main class here]</mainClass>
