Eclipse build repositories

Eclipse Project builds are stored in p2 repositories that are produced as part of the Eclipse project build process. This page provides an overview of the different repositories maintained by the Eclipse project, and their corresponding location and retention policy. See also meaning of kinds of builds.

NOTE: Nightly builds are produced (nearly) every night from whatever has been released into the HEAD stream of the code repository. They are completely untested and will almost always have major problems. Because nightly builds are produced in a different way from integration builds, the nightly build repository should only be used in conjunction with nightly builds.

See the online help article Adding a new software site for instructions on how to add a new update site to your Eclipse installation.

Repository Repository URL Retention Policy
4.5 milestones (Mars)
stable builds, roughly 6 week intervals
http://download.eclipse.org/eclipse/updates/4.5milestones Retained until the release is available.
To save space on mirror servers for rarely requested downloads only about 2 of the most recent milestones will be kept on "downloads" server, older ones may be moved to "archives", temporarily, until formal release, when they are removed completely.
Note, all milestone builds and release candidates, except the last one, are removed approximately one week before a formal release date, to free up space on eclipse.org and mirror servers.
Integration builds toward 4.5
weekly builds, used by developers of SDK components
http://download.eclipse.org/eclipse/updates/4.5-I-builds I-builds are removed once a milestone is available, or earlier at the request of the development team.
Nightly builds toward 4.5
daily snapshots; not for production
http://download.eclipse.org/eclipse/updates/4.5-N-builds
Don't mix with non-N repositories!
Builds removed after a few days old.
Because nightly builds are produced in a different way from integration builds, the nightly build repository should only be used in conjunction with nightly builds.
Maintenance builds toward 4.4.x (Luna) http://download.eclipse.org/eclipse/updates/4.4-M-builds Builds removed after about a month old, or at the request of the development team
