JDK14新建javafx+Maven项目

1.在IDEA中创建Maven项目：

2.完成新建后项目结构如下：

3.选择项目环境结构（New创建JDK指定到自己的JDK14所在目录就可以了）

4.在src/main/java中加入AppLauncher 启动类（原因：可以绕过Application启动检查，不然会在打包后报错"缺少javafx运行时组件"），代码如下

package com.xzl;

import javafx.application.Application;

public class AppLauncher {
    public static void main(String[] args) {
        Application.launch(JavaFxApplication.class,args);
    }
}

5.在src/main/java中加入javafx启动类，代码如下

/**

 * Date:     2020/3/12/012 19:50
 */
package com.xzl;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.HBox;
import javafx.scene.text.Text;
import javafx.stage.Stage;

/**
 * @author xzl
 * @create 2020/3/12
 */
public class Applicaion extends Application {
    public static void main(String[] args) {
        launch(args);
    }
    @Override
    public void start(Stage stage){
        Text text = new Text("JDK14，javafx11瘦身啦");
        HBox sceneBox = new HBox(text);
        sceneBox.setStyle("-fx-alignment: center;-fx-text-fill: red;-fx-background-color: transparent;-fx-border-color: green;-fx-font-size: 1.8em;");
        Scene scene = new Scene(sceneBox,600,400);
        stage.setScene(scene);
        stage.show();
    }
}

6.在pom.xml中配置如下(注：当前项目中只用到了javafx相关，加入netty是为了后面项目打包示范)

</project>

7.点击运行AppLauncher.java

重点： 注意pom文件中的打包方式–将Maven依赖打入jar包，是后续瘦身打包的前提！

jpackage工具参考：JDK14打包工具jpackage的使用
