Jason van Zyl commented on MNG-2443:
------------------------------------
That an artifact having been incorrectly deployed without a POM doesn't mean
that a POM should not be added in the future. I just hit this with Velocity
View Tools where there is no POM but I ask them to correct it. A POM simply
should not be deployed without a POM in the first place but we assume that it
may be corrected in the future, not that it will never be corrected. We really
need to correct the projects without POMs, always make the attempt in the
background, but not show this constant downloading to the user.
Once a POM is present it will never to downloaded again, but as long as this
annoying message is not in your face all the time. A silent attempt in the
background probably won't do much harm and is the safest approach with
attempting but not annoying the user with the output.

> Project: Maven 2
> Issue Type: Bug
> Components: Artifacts and Repositories
> Affects Versions: 2.0.4
> Reporter: Carsten Ziegeler
> Fix For: 2.1

>
> There are many projects out there just providing their artifact without a pom
> (whether this is good or not is a different question). Now in this case m2
> always tries to download a pom for those artifacts, even if the artifact
> itself is already in the local repository. And if you have several of those
> artifacts combined with more than one repository configured, then there are a
> lot of unnecessary download attempts.
> I think this falls into the same category as changing a pom in the repository
> (which should be forbidden) - so if for the first time the artifact is
> downloaded no pom available, then there will never be a pom for this specific
> artifact.
