> Am really unsure about all this: IMHO it is completely enough for resolver
to state "unable to resolve GAV" (something that is absent or present in local
repo, and that message is already present), instead to go great lengths and try
to figure out instead of user. As you listed, there are MANY tricky situations,
like lack oof (or wrong) auth credentials, but again, that does NOT guarantee
that if fixed, artifact will be resolved.
>
> IMHO, we should just increase the level of logged causes (maybe even for
all tried repositories) and let user figure out?
This is why I have asked. How should be an absent dependency defined? Only
not found or anything else too? That is why this is a draft.

> Consider you have three repos defined in your build (could be POM or
> settings), evaluated in following order:
> 1. repo A: serves custom artifacts with group id {{com.example}}, due to repo
> partitioning in Nexus rejects requests to all other group ids with 403
> 1. repo B: serves third party artifacts without any restriction from a Nexus
> repo
> 1. repo C: serves Central mirror, last one quried, no restrictions
> Note that order is important! Now add a non-existing dependency to your POM
> and receive the following behavior:
> {{ArtifactResolutionException}} will contain an {{ArtifactResult}} with three
> exceptions:
> - {{TransferException}} with nested {{AuthorizationException}},
> - {{ArtifactNotFoundException}},
> - {{ArtifactNotFoundException}}.
> {{ArtifactResolutionException#getCause()}} will be populated with the
> {{TransferException}} so will
> {{org.eclipse.aether.resolution.ArtifactResult.isMissing()}} take the first
> exception only into account. E.g., {{DefaultArtifactDescriptorReader}} will
> do {{if (e.getCause() instanceof ArtifactNotFoundException)}} which is
> deceiving.
