Eclipse Project Update Sites

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
4.6 milestones (Neon)
stable builds, roughly 6 week intervals
http://download.eclipse.org/eclipse/updates/4.6milestones 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 4.6
weekly builds, used by developers of SDK components
http://download.eclipse.org/eclipse/updates/4.6-I-builds I-builds are removed once a milestone is available, or earlier at the request of the development team.
Nightly builds toward 4.6
daily snapshots; not for production
http://download.eclipse.org/eclipse/updates/4.6-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 4.5.x (Mars) http://download.eclipse.org/eclipse/updates/4.5-M-builds Builds removed after about a month old, or at the request of the development team
 
4.5.x releases (Mars) http://download.eclipse.org/eclipse/updates/4.5 Retained Indefinitely
4.4.x releases (Luna) http://download.eclipse.org/eclipse/updates/4.4 Retained Indefinitely
4.3.x releases (Kepler) http://download.eclipse.org/eclipse/updates/4.3 Retained Indefinitely
4.2.x releases (Juno) http://download.eclipse.org/eclipse/updates/4.2 Retained Indefinitely
3.8.x releases (Juno) http://download.eclipse.org/eclipse/updates/3.8 Retained Indefinitely
3.7.x releases (Indigo) http://download.eclipse.org/eclipse/updates/3.7 Retained Indefinitely
3.6.x releases (Helios) http://download.eclipse.org/eclipse/updates/3.6 Retained Indefinitely
3.5.x releases (Galileo) http://download.eclipse.org/eclipse/updates/3.5 Retained Indefinitely
3.4.x releases (Ganymede) http://download.eclipse.org/eclipse/updates/3.4 Retained Indefinitely

Non-versioned repository URLs

There are some special composite repository URLs that are primarily intended for committers and earlier testers. They are each a composite that simply points to the current version of the repositories listed above. This is most useful once per year as we change streams, such as from 4.5, to 4.6. At that time, then the composite on the server is changed to point to the N+1 repository instead of the N repository, so those using the non-versioned URL do not need to change their software repository lists or scripts. In other words, the contents are identical to their current, versioned counterparts, but the URL stays the same.

Repository Repository URL Retention Policy
Current Milestones http://download.eclipse.org/eclipse/updates/milestones Same as above.
Current Integration builds http://download.eclipse.org/eclipse/updates/I-builds Same as above
Current Nightly builds http://download.eclipse.org/eclipse/updates/N-builds
Don't mix with non-N repositories!
Same as above.
Current Maintenance builds http://download.eclipse.org/eclipse/updates/M-builds Same as above.
