shade、proguard 和 appassembler maven 插件的组合

Question

我正在尝试使用 Maven 构建和混淆多模块项目。我使用 shade 插件创建一个包含我自己的所有 class 文件（每个模块）的 fat jar，这样我就可以使用 proguard-maven-plugin 混淆 fat jar，然后使用 appassembler 插件创建可执行构建输出。一切正常，除了其他模块依赖项也出现在 appassembler repo 目录中，这是错误的，因为混淆的 classes 已经存在于阴影 jar 中。

我试过按照提供的方式定义其他模块依赖项，然后添加 shade 插件的依赖项，但 shade 插件似乎忽略了它们。

这是pom.xml的相关部分：

欢迎提出任何想法。

Answer 1

我认为你的问题是因为 shaded jar 和 appassembler 运行在同一阶段 package.

我认为你应该尝试将 appassembler 插件的阶段修改为：

<phase>post-package</phase>

Answer 2

我找到了一个解决方案，它不像我想要的那样方便，但比手动删除其他模块 jar 更好。我使用程序集插件从构建分发 zip 中排除了 jar。
