Vis*_*kia 7 dependency-management maven-plugin maven transitive-dependency maven-shade-plugin
我使用了Apache Maven Shade Plugin来创建胖jar(包含所有依赖项的所有类的jar).我当前的项目文件夹结构看起来像这样,
> Parent Module (packaging pom)
> Module 1 (packaging jar)
> Own classes
> Dependency-1
> Dependency-2
> Module 2 (packaging jar)
> Own classes
> Module 1 (I want here only classes written in module-1, not any transitive dependencies)
> Dependency-1
> Dependency-2
> Dependency-3

pom.xml来自父模块的快照,

pom.xmlModule-1和Module-2 的快照看起来像这样,

在Module-2 pom中为Module-1声明的依赖关系看起来像这样,
<dependency>
<groupId>my.com.groupId</groupId>
<artifactId>my.artifactId</artifactId>
<version>1.0.0-SNAPSHOT</version>
<exclusions>
<exclusion>
<groupId>*</groupId>
<artifactId>*</artifactId>
</exclusion>
</exclusions>
</dependency>

注意:目前,如果我看到我的依赖项使用mvn dependency:tree -Dverbose,那么它将按预期显示,但shade-plugin不排除它.
问题:module-1和module-2具有不同版本的相同依赖关系.如果我跳过/禁用Module-1中声明的shade-plugin,那么我可以运行Module-2而没有任何问题,但如果我不禁用它,那么Module-2创建的fat jar包含一些来自jar的jar类-1版本,所以我的Module-2停止运行.
更新:
我使用胖罐来运行这样的单个模块,
java -cp module.jar com.mycom.Main
有什么帮助吗?
