1、添加JavaFX 11依赖项

1）Maven的Pom.xml配置

<dependencies>
    <dependency>
        <groupId>javafx</groupId>
        <artifactId>javafx.controls</artifactId>
        <version>11.0.0</version>
    </dependency>
</dependencies>

2）Gradle配置

dependencies {
    compile 'javafx:javafx.controls:11.0.0'
}

2、JavaFX Application类

public class JavaFX11 extends Application {
    @Override
    public void start(Stage stage) throws Exception {
        Scene scene = new Scene(new StackPane(new Label("JavaFX 11")), 300, 200);
        stage.setScene(scene);
        stage.show();
    }
}

3、编译代码

<path.to>/jdk-11.jdk/Contents/Home/bin/javac --module-path <path.to>/javafx-sdk-11/lib/ --add-modules=javafx.controls -d class/ src/<package.name>/JavaFX11.java

4、运行上面的JavaFX示例程序

cd class
<path.to>/jdk-11.jdk/Contents/Home/bin/java --module-path <path.to>/javafx-sdk-11/lib/ --add-modules=javafx.controls <package.name>.JavaFX11
