Eclipse update (rarely) works: No repository found containing -- many entries

Question

I don't understand, why Eclipse update made so unreliable? Approximately each time I use it, I meet some problem!

For example, now I meet bunch of delirium below. Disabling "Contact All Software Sites" does not help.

An error occurred while collecting items to be installed
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Answer 1

I solved this by disabling all superflous update sites.

This is the base update sites I ended up with:

• EGit P2 Repository http://download.eclipse.org/egit/updates Enabled
• Mylyn for Eclipse Luna http://download.eclipse.org/mylyn/releases/luna Enabled
• The Eclipse Web Tools Platform (WTP) software repository - http://download.eclipse.org/webtools/repository/luna Enabled
• The Eclipse Project Updates http://download.eclipse.org/eclipse/updates/4.4 Enabled

I also had this update site enabled:

Luna http://download.eclipse.org/releases/luna Disabled

which I had to disable to get rid of the egit errors. Turns out http://download.eclipse.org/releases/luna contains egit and eclipse doesn't manage to choose between that version and the one in "EGit P2"... (omg)

I assume http://download.eclipse.org/eclipse/updates/4.4 also overlap with the releases/luna repo

I also diasbled all update sites pointing to older releases (kepler, etc)

Answer 2

Something happened in m2e plugin, so to get rid of this exception you have to disable its repository. Check the selection in the screenshot below:

Go to:

Help -> Install new software -> Available software sites -> Disable selection (from screenshot)

Answer 3

Whenever you try to add new software/plugin to eclipse it will also try to install/update the existing software sites. You can disable or remove those are causing issues and you don't want any updates from those software sites. In my case where I am using Luna I had to disable "Mylyn 3.18 for Eclipse 3.8, 4.4 and 4.5 - http://download.eclipse.org/mylyn/releases/latest" and disable " http://download.eclipse.org/technology/m2e/releases". The updates are not working may be because of mismatch in the eclipse version and plugin (not sure, please correct me if I am wrong). The way to disable these software sites in eclipse is windows -> preferences -> Availabe software sites

Answer 4

In my case the problem was caused by not having the m2eclipse update site ( http://download.eclipse.org/technology/m2e/releases/ ) in Help -> Install new software -> Available software sites.

The problem dissapeared after adding it there.
