我需要使用 Reflections在带有 JavaFX 的 maven 项目中，我想使用 jlink捆绑一个最小的 JRE。
问题是在运行 mvn clean compile javafx:jlink 时出现以下错误:

[WARNING] Required filename-based automodules detected. Please don't publish this project to a public artifact repository!
Error: automatic module cannot be used with jlink: reflections from file:///C:/Users/Daniel/.m2/repository/org/reflections/reflections/0.9.12/reflections-0.9.12.jar

问题是反射不支持 JPMS 和 jlink仅需要显式模块。
我看过 this answer描述了如何将外部 JAR 转换为模块，但我需要在运行 jlink 之前在我的 maven 构建中自动执行此操作.
我也遇到了 moditect这完全允许，但我没有在我的项目中完成这项工作，因为我不知道如何告诉 javafx:jlink使用 Reflections-library 的转换后的 JAR
我也可以想象使用 exec-maven-plugin 运行 jlink 命令，但我不知道如何告诉 javafx-maven-plugin 在不修改本地存储库的情况下采用该命令。
如何使用 jlink -javafx-maven-plugin 的目标同时将自动化模块(反射)作为依赖项？

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 (也简化了):

为什么要坚持专门使用这个工具链？您可以使用 jlink 创建 JavaFX 程序，而无需先将所有内容模块化。也许您可以按照我在这里与 Dirk 描述的路线进行操作:https://github.com/dlemmermann/JPackageScriptFX好处基本相同，我看不到对整个应用程序使用 jlink 的任何额外好处。
