Guillaume Nodet updated MNG-8171:
---------------------------------
Fix Version/s: 4.0.0-beta-5
> Artifact with project.rootDirectory causes Maven to expect a root directory
> in local repository
> -----------------------------------------------------------------------------------------------
>
> Key: MNG-8171
> URL: https://issues.apache.org/jira/browse/MNG-8171
> Project: Maven
> Issue Type: Bug
> Affects Versions: 4.0.0-beta-3
> Environment: Windows 11, Java 22
> Reporter: Christian Bühler
> Priority: Major
> Fix For: 4.0.0-beta-5
>
>
> When including artifact A (that uses {{project.rootDirectory}} in its POM) in
> artifact B using {{maven-dependency-plugin:copy}}, Maven tries to evaluate
> artifact A's POM inside the local repository and expects to find a root
> directory. This breaks the build.
> Artifact B must be under a different parent/in a different source repository,
> otherwise Maven resolves the artifact from {{target/project-local-repo}} and
> can find a root directory. The workaround for this is creating {{.mvn}}
> directory in the root of the local repository.
> I think this is a bug, but not sure where the root cause is and couldn't find
> an existing issue for this.
