Re: Mirrors and repositories
Ahhh - here we go - So I'm working on rolling out a corp pom for a company who doesn't have one right now. The corp pom is a completely different maven project/jenkins build and structurally, unrelated to the other projects that list it as a parent. The current version of this corp pom is 1.0-SNAPSHOT and it's deployed to my snapshot repository within Nexus. The grouped up repository in Nexus includes this snapshot. When I was building without the additional repository defined, maven (maven 3.0.3) was unable to find the parent pom. Once I added this extra repository, boom - it all works. What's extra confusing is I have mirrorOf*/mirrorOf - shouldn't that say this url is a mirror of EVERYTHING? I'm basing this all on this link: http://maven.apache.org/guides/mini/guide-mirror-settings.html (thank you Wendy!)

This is exactly why ^^ You need to do the same for pluginRepositories if you ever want to get snapshots of plugins. - To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
Re: Mirrors and repositories
Snapshots of plugins are explicitly banned as are not specifying versions of plugins and relying on maven's super pom (years ago, I got whacked with this when the war plugin changed). But I'm not saying I'm mirroring JUST central, I thought I was saying I'm mirroring every repository you could possibly need. See my comment about the mirrorOf*/mirrorOf.

No, it just means, When you go through your list of known repositories, substitute this url instead of the original one defined. -- Wendy - To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
Re: Mirrors and repositories
Edwin Punzalan a écrit : Mykel is correct. In addition, until MNG-714, when the mirror fails to deliver, the mirrored repository is not used. So are mirrors of the same repository id.

You're running a maven-aware proxy (like proximity or maven-proxy) and that proxy knows about central and you want to override the URL for central to your proxy. 2. You know of a geographically closer mirror to some repo (often central) and you want to use that mirror rather than the original one.
