Szczepan Faber commented on MNG-714:
------------------------------------
There are number reasons this is a valuable feature:
-ability to implement simple fail-over system with two mirrors mirroring the
same repo(s)
-currently, if there are mirrors with the same value of "mirrorOf", last mirror
wins and previous mirrors are silently ignored. Not very nice...
-some folks from my company have to change the settings file every time they go
home because at home they don't have proxy. Quite annoying...
Is it going to be released into maven? Is "improving maven" in the agenda of
maven roadmap?

> Key: MNG-714
> URL: http://jira.codehaus.org/browse/MNG-714
> Project: Maven 2
> Issue Type: Bug
> Components: Artifacts and Repositories
> Affects Versions: 2.0-beta-1
> Reporter: Kenney Westerhof
> Assignee: Jason van Zyl
> Fix For: 3.x
>
> Attachments: MNG-714-maven-artifact-manager.patch

> Original Estimate: 3 hours

> I'm using the settings.xml mirror feature as a local cache. Periodically I
> upload my local repo
> to the webserver specified as mirror.
> When an artifact cannot be found on the mirror, the original site isn't
> checked (and possibly the rest of the sites).
> I'm not sure what the exact function of the mirror is (except caching?), but
> repo1 is checked often regardless
> of mirror presence, so I figure it's not meant to totally disable checking
> the central repo's.
> Simple reproduction: define a few mirrors in your settings.xml for central,
> central-plugins and snapshots, pointing to
> say file://tmp/empty/dir/.
> Stacktrace:
> [DEBUG] Error resolving artifact version from metadata.
