Paul Gier commented on MDEP-405:
--------------------------------
I think the reason this happens is because in order to determine the full set
of transitive dependencies to delete, the poms need to be available. If the
poms were already resolved in the previous module, Maven won't re-resolve them
again and just fails. So the dependency doesn't have a problem with the file
already being deleted from the local repo, but the maven dependency resolution
code fails when trying to resolve the same file twice in the same build.
You might try the build with Maven 3.0.3 because there was a change in this in
Maven 3.0.4:

> purge-local-repository on multi-module project results in failure

>
> Key: MDEP-405
> URL: https://jira.codehaus.org/browse/MDEP-405
> Project: Maven 2.x Dependency Plugin
> Issue Type: Bug
> Components: purge-local-repository
> Affects Versions: 2.6
> Reporter: Stephen Cooper
>
> I have several multi-module projects all suffering from this issue.
> As a post-build step in jenkins, we want to clean up the repository to keep
> disk space usage to a minimum.
> We execute the following:
> {code}
> mvn -f pom.xml -DsnapshotsOnly=false -DreResolve=false -Dverbose=true -e
> -Dmaven.repo.local=/var/lib/jenkins/maven-repositories/12
> dependency:purge-local-repository
> {code}
> We have reresolve set to false so that the files don't get downloaded again.
> This works fine for the first modules, but once we hit a module which has the
> same dependencies as a previous module, we get an error that we cannot
> resolve dependencies and the build fails.
