gordon cody commented on MRESOLVER-55:
--------------------------------------
[~michael-o] There are no errors in our artifactory.log and there is nothing in
our artifactory request log except for lines with 200(OK) so I don't think the
artifactory is even seeing the request that fails. The errors happen on our CI
system when multiple builds are going on so I think it is due to network
congestion. Sorry, but I am not sure what you mean by "fully on your side".
In the build log just before the connect timeout occurs there is this info:

> Key: MRESOLVER-55
> URL: https://issues.apache.org/jira/browse/MRESOLVER-55
> Project: Maven Resolver
> Issue Type: Bug
> Components: resolver
> Affects Versions: Maven Artifact Resolver 1.1.1
> Environment: Windows, Ubuntu
> Reporter: Lasse Westh-Nielsen
> Priority: Major
> Fix For: waiting-for-feedback
>
>
> Hey,
> We often run Maven builds of [https://github.com/neo4j/neo4j] on machines
> with cold caches/ empty ~/.m2/repository folders.
> There are rather a lot of dependencies to download, so even though the
> failure rate of individual artifact downloads is small, at our scale it
> causes significant build failures.
> I am working on seeding caches. Separately though it would be great to be
> able to configure retries and timeouts for dependency downloads - optimise
> for build throughput rather than latency as it were.
> How do I do that? I can't find it documented anywhere, and trying to browse
> "wagon" source code got me nowhere.
> Regards,
> Lasse
