Ivan S. Dubrov commented on MNG-5315:
-------------------------------------
No, it's not repository related. The issue never happens in a single-threaded
build. It looks like it happens due to the race-condition between two threads
trying to download the same artifact at the same time. Also, even though build
is failed the dependency is actually downloaded into the local repository (so
you can see it there after the build fails).
Something like (just speculating):
1) first thread looks into the local repository, nothing there, goes to the
remote repository
2) first thread downloads remote dependency, but does not update
_maven.repositories yet.
3) second thread looks into the local repository, sees the dependency, but
_maven.repositories does not contain remote repository id!
4) second thread fails with "Could not resolve dependencies", since it thinks
dependency is not available from the remote repository.
5) first thread updates _maven.repositories. Next time build is invoked,
dependency is used from the local repository.

> Key: MNG-5315
> URL: https://jira.codehaus.org/browse/MNG-5315
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Artifacts and Repositories
> Affects Versions: 3.0.4
> Reporter: Ivan S. Dubrov
> Priority: Minor
>
> Artifact resolution can fail during the parallel build if it was downloaded
> during the same session.
> Scenario:
> 1) Delete the whole Maven local repository.
> 2) Run build "mvn compile -T1.5C"
> 3) Build fails (see log extracts below)
> 4) If I run build again, it succeeds.
> It seems like the problem is due to two thread trying to resolve same
> artifact concurrently. This problem never happens once I have all
> dependencies cached in the local repository.
