Re: [tycho-user] Intermittent download failure of p2

[Jeff MAURY <jeffmaury@xxxxxxxxxxxxx>]

I'm leading an Xtext based product. This product is validated against 3.5, 3.6, 3.7, 3.8, 4.2 and 4.3 versions of Eclipse thanks to P2 target files.
Apart from Kepler (4.3) which p2 repository is broken, each other P2 repo is mirrored by my Nexus instance and it has both stabilized and improved the build time of my product.

Regards
Jeff

I've tried this in the past (nearly a year ago I think) and found the cpu/memory consumption too high for my nexus server (it was running on an EC2 micro server) leading to out of memory errors - particularly for something large like the indigo repository.  You will need a beefier machine than usual to run it. Of course, things might have improved since I last tried it.

Additionally, I believe people are having success mirroring p2 repositories automatically using software like Sonatype's Nexus.  Perhaps someone could comment on that, as it's something I'd like to look at doing myself?

Thanks,

Chris

Have you looked at mirroring the remote p2 repositories? This will avoid your dependence on external servers.

Hi,

We have intermittent download failures from official Eclipse p2 repository in our Tycho build on our CI platform. See log: http://pastebin.com/mEtBey3Z

Note that we are purging local Maven repository frequently.

Here is my target platform definition: https://github.com/SonarSource/sonar-eclipse/blob/master/target-platform/target-platform-e42.target

Is there a way to configure Tycho with a retry count or something like that?

Regards,

Julien
