我正在使用 JDK11 和 JavaFX11。
我使用 Jlink 为我的示例 FX 模块程序创建了一个自定义 JRE,但是当我尝试使用自定义 JRE 运行时,它会呈现如下错误:
这就是我创建自定义 JRE 的方式(没有错误):
jlink --module-path ..\jmods;%PATH_TO_FX% --add-modules java.base,java.desktop,jdk.unsupported,javafx.graphics --output FXJRE
这就是我尝试运行的方式(有错误):
FXJRE\bin\java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo
错误消息:

这是我的编译方式:
源 JavaFXDemo.java:
package com.javafxdemo;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
public class JavaFXDemo extends Application {
@Override
public void start(Stage stage) {
stage.setTitle("Hello World");
Group root = new Group();
Scene scene = new Scene(root, 300, 250);
Button btn = new Button();
btn.setLayoutX(100);
btn.setLayoutY(80);
btn.setText("Hello World");
btn.setOnAction(actionEvent -> System.out.println("Hello World"));
root.getChildren().add(btn);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
module-info.java
:
module com.javafxdemo {
requires javafx.base;
requires javafx.graphics;
requires javafx.controls;
exports com.javafxdemo;
}
我就是这样编译的。
javac -d mods\com.javafxdemo --module-path %PATH_TO_FX% src\com.javafxdemo\module-info.java src\com.javafxdemo\com\javafxdemo\JavaFXDemo.java
编译后,我的模块类文件如下:
├───mods
│ └───com.javafxdemo
│ │ module-info.class
│ │
│ └───com
│ └───javafxdemo
│ JavaFXDemo.class
│
└───src
└───com.javafxdemo
│ module-info.java
│
└───com
└───javafxdemo
JavaFXDemo.java
我可以成功运行如下:
java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo
不过,我可以使用默认的 JDK11 运行。
如何成功创建自定义 JRE 并使用它运行示例 FX 模块程序?
