I tried upgrading from Luna to Mars by following the instructions here: https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse%3F

I added the Mars repository http://download.eclipse.org/releases/mars as an update site and then did check for updates. But I get the exception 

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=).

How can I fix this?

Before upgrading I first check the availables web sites for update. I disable all from the previous releases and start by performing an update on the already installed components. After this upgrade I just add

http://download.eclipse.org/releases/mars

and upgrade to the new release of eclipse.
