使用JavaFX和maven将模块描述符添加到库中

Question

我需要在带有JavaFX的maven项目中使用Reflections，并且我希望使用jlink来捆绑最小JRE。

问题是我在运行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Reflections不支持JPMS，jlink只需要显式模块。

我已经看到了这个答案，它描述了如何将外部JAR转换为模块，但在运行jlink之前，我需要在我的maven构建中自动执行此操作。

我也遇到了允许这样做的moditect，但我没有在我的项目中做到这一点，因为我不知道如何告诉javafx:jlink使用反射库的转换JAR

我还可以想象使用exec-maven-plugin来运行jlink命令，但我不知道如何告诉javafx-maven插件在不修改本地存储库的情况下执行该命令。

如何使用jlink-javafx-maven-plugin的目标，同时将自动模块(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(也很简单(：

为什么坚持要专门使用这个工具链？您可以使用jlink创建JavaFX程序，而不必首先将所有内容模块化。也许你可以遵循我在这里与德克描述的路线：https://github.com/dlemmermann/JPackageScriptFX好处基本上是一样的，我看不出对整个应用程序使用jlink有任何额外的好处。
