java - ModiTect 和 Jlink 找不到模块依赖项

Question

我已经配置了ModiTect生成 module-info.java s 对于我所有的依赖项(没有它们)，这似乎是有效的；但是当涉及到确实拥有它们的依赖项时，它并没有找到它们。对于我自己的 jar ，我正在写 module-info.java用手。

当我运行 mvn package在我的应用程序中它失败了:

Error: Module tech.flexpoint.dashmancommon not found, required by tech.flexpoint.dashmanserver

命令行如下所示:

C:\Program Files\Java\jdk-10.0.1\bin\jlink --add-modules tech.flexpoint.dashmanserver --module-path C:\Users\pupeno\Documents\Dashman\code\dashmanserver\target\modules;C:\Program Files\Java\jdk-10.0.1\jmods;C:\Users\pupeno\Documents\Dashman\code\dashmanserver\target\classes --output C:\Users\pupeno\Documents\Dashman\code\dashmanserver\target\jlink-image --launcher dashmanserver=tech.flexpoint.dashmanserver

我知道 tech.flexpoint.dashmancommon是一个模块并且有一个 module-info.java因为我自己 build 的。如何让 ModiTect/jlink 在其原始 jar 中找到所有依赖模块？

我正在 build 的 ModiTect 配置如下所示:

</plugin>

如果我添加

<path>c:\Users\pupeno\.m2\repository\tech\flexpoint\dashmancommon\1.0.0-beta.11</path>

到我的 ModiTect 配置，它开始工作，生成这个命令行:

C:\Program Files\Java\jdk-10.0.1\bin\jlink --add-modules tech.flexpoint.dashmanserver --module-path c:\Users\pupeno\.m2\repository\tech\flexpoint\dashmancommon\1.0.0-beta.11;C:\Users\pupeno\Documents\Dashman\code\dashmanserver\target\modules;C:\Program Files\Java\jdk-10.0.1\jmods;C:\Users\pupeno\Documents\Dashman\code\dashmanserver\target\classes --output C:\Users\pupeno\Documents\Dashman\code\dashmanserver\target\jlink-image --launcher dashmanserver=tech.flexpoint.dashmanserver

我想这证实了该模块的工作原理并已安装。我只是不确定如何让 ModiTect 找到它(没有可怕的硬编码路径)。

Answer 1

我认为您的问题对应于 this moditect 的已知问题。
当前不支持从碰巧已经是模块的 maven 依赖项子集生成模块路径。解决方法是使用 maven-dependency 插件将它们复制到可以添加到模块路径的已知目录中。
