[cross-project-issues-dev] Intermittent p2 failures, best practices for "mirroring"

[Kevin Browder]

So we've been occasionally getting failures on
http://download.eclipse.org/releases/oxygen/201804111000/content.xml.xz and
other similar sites over this past week (including this morning EDT). From
the archive I see this has been an issue this past week so I guess you guys
are doing something about it but I have some questions relating to setting
up a cache that may save you a small amount of bandwidth.


Does tycho support some form of fail-over such that if we set up a cache
for p2 and that server goes down we can fail back to the internet? I'm
using maven+tycho and at one point it seemed like adding multiple p2 repos
didn't really help for some cases of failure (the other repo wouldn't get
tried), but this was forever ago so maybe i'm miss-remembering or the
situation was very specific.

Also is there a preference for caching proxies for those of us who want to
stay on the FOSS side of things (even if we get support later). I've used
Nexus 2.x (still do) but it's p2 support wasn't great at the time from what
i could tell; I'm looking a bit at Artifactory, is it worth switching?
There's nexus 3.x as well

Any advice would be greatly appreciated
Thanks
Kevin

Kevin,

Tycho supports official mirrors specified in the p2 repository as well as internal mirrors. They have a user mailing list in case you need further help setting this up.
https://wiki.eclipse.org/Tycho/Target_Platform/Authentication_and_Mirrors


FWIW, I'd like to take this as an opportunity to remind everyone about the purpose of this mailing list. It's for important communication for projects participating in the Eclipse Simultaneous Release. I prefer having discussions in the proper channels, which allow the whole community to participate (and potentially re-discover answers).

Ah sorry about the wrong mailing list, I'd mostly seen a few other issues
related to this here and figured I'd go for it, but you're right I should
have looked for a more appropriate channel.
Thank you for the link in anycase, it's very helpful
