java – ProGuard不会模糊JAR的依赖关系

我有一个项目与下面给出的pom.xml文件.当我发出命令mvn clean compile assembly：single install我想要Maven生成一个JAR,其中包含

>所有的依赖和
>我的代码的模糊版本.

它不起作用 – 我的代码在“jar-with-dependencies”文件中没有被模糊化.

当我运行mvn clean编译安装生成的文件包含我的应用程序的模糊代码,但没有依赖关系.

为了拥有一个具有所有依赖关系和我的混淆代码的JAR文件,我该怎么办？

更新1(17.01.2016 19:54 MSK)：更改了ProGuard配置,如下所示,但是mvn clean编译程序集：single仍然使用无模糊化的类文件生成JAR.

更新2(17.01.2016 20:29 MSK)：mvn clean compile assembly：single install failed.最后的消息可以看出here.

解决方法

proguard-maven-plugin将模糊项目的主要工件,而不是maven-assembly-plugin生成的辅助工件jar-with-dependencies.

您需要配置插件以通过指定injar属性来模糊jar-with-dependencies：
