>             Project: Maven Artifact Plugin
>          Issue Type: Bug
>            Reporter: Niels Basjes
>            Priority: Major
>              Labels: pull-request-available

> In my projects I often use the *maven-shade-plugin* to include specific dependencies  in the final jar.
> I do this to avoid version conflicts in dependencies that are very version sensitive like the Antlr4 runtime ( See [https://yauaa.basjes.nl/developer/shadingdependencies/] ).
> So in practice I use the following shading options
>  * relocate: to different package name
>  * minimizeJar: to only keep what is needed
>  * *useDependencyReducedPomInJar* : to make sure that down stream applications do not include the original dependencies anymore that have already been included. https://maven.apache.org/plugins/maven-shade-plugin/shade-mojo.html#useDependencyReducedPomInJar 
> An important note about the useDependencyReducedPomInJar is that the actual *pom.xml* that is placed in the jar file has been generated during the build and is thus very different from the *pom.xml* file that is part of the source code.
> When I now run the *compare* goal of this artifact plugin I get this:
> {code:java}
> [ERROR] size mismatch yauaa-7.13.1-SNAPSHOT.pom: investigate with diffoscope analyzer/target/reference/yauaa-7.13.1-SNAPSHOT.pom analyzer/pom.xml {code}
> To me this looks like the goal is comparing the pom of the published jar (generated file; without the shaded dependencies) with the source file (with the shaded dependencies).
> If I do this
> {code:java}
> $ diffoscope analyzer/target/reference/yauaa-7.13.1-SNAPSHOT.pom analyzer/dependency-reduced-pom.xml  {code}
> They are equal.
