Dennis Homann commented on MNG-4354:
------------------------------------
I just stumbled upon a problem which sounds related:
* an artifact was resolved from a remote mirror and placed in the local
repository, along with a file _maven.repositories which points to the ID of
mirror where the artifact was resolved from
* when I disconnect from the network, Maven will try to resolve the artifact
from remote repositories although it is present locally, and the build will fail
* when I disconnect from the network AND run with -o, Maven will fail with "The
repository system is offline but the artifact ... is not available in the local
repository."
* when I delete the _maven.repositories file for the artifact in question, it
will get resolved locally and the build will fail for the next dependency as
described above
> DefaultArtifactResolver has problems when used with multiple repos

> DefaultArtifactResolver attaches the repositories to artifacts (AFAIK) to
> optimize the repo look ups.
> Here I have a case
> 1) An artifact dependens on org.eclipse.equniox:app:1.2.0
> 2) org.eclipse.equinox:app depends on
> org.eclipse.equinox:registry:[3.4.0,4.0.0)
> 3) Both central repo and custom corporate repo has
> org.eclipse.equinox:registry
> 4) central repo has outdated versions
> 3.2.1-R32x_v20060814
> 3.3.0-v20070522
> 5) DefaultArtifactResolver for optimization attaches central repo (last one
> wins)
> 6) Central repo neither satisfies the version range nor - even if it did -
> has the latest version
> 7) dependency is not satisfied
> 8) Build halts
> Attached patch is a dirty hack to disable signle repo downloand and checks
> all the repositories.
