使用Javafx和Maven添加模块描述符到库中

 2023-02-16    478  

问题描述

我需要使用反射在带有Javafx的Maven项目中，我想使用jlink>捆绑最小的JRE.

问题是我在运行mvn clean compile javafx:jlink时会遇到以下错误:

使用Javafx和Maven添加模块描述符到库中

问题是反射不支持JPM，jlink仅需要明确的模块.

我已经看过这个答案描述了如何将外部罐子转换为模块，但我需要自动执行此操作在运行jlink之前，我的Maven构建中.

我还遇到了 moditect 完全允许这一点，但我没有在项目中进行工作，因为我不知道如何告诉javafx:jlink使用转换后的反射罐library-library

我也可以想象使用 exec-maven-plugin 命令，但我不知道如何告诉javafx-maven-plugin在不修改本地存储库的同时采用它.

如何在以自动模块(反射)为依赖性时使用javafx-maven-plugin的目标?

我的module-info.java看起来像这样(简化):

module my.project{
    exports my.project.toscan to reflections;
    exports my.project.ui to javafx.graphics;
    opens my.project.ui.controllers to javafx.fxml;
    requires javafx.controls;
    requires javafx.fxml;
    requires transitive javafx.graphics;
    requires javafx.base;
    requires reflections;
}

这是我的pom.xml(也简单):

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

推荐答案

为什么您坚持使用此工具链?您可以使用JLINK创建Javafx程序，而不必首先将所有内容模块化.也许您可以在此处遵循我与Dirk一起描述的路线: A>基本上的好处是相同的，我看不到将JLINK用于整个应用程序的任何其他好处.

以上所述是小编给大家介绍的使用Javafx和Maven添加模块描述符到库中,希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对77isp云服务器技术网的支持！
