An error occurred while collecting items to be installed session context was:

I've solved it by downloading the repository from a hidden link:

http://dl.google.com/eclipse/plugin/core/3.7/zips/gpe-e37-latest-updatesite.zip

and updating from there

See the documentation on Google's website.

This is still an issue if you're behind a firewall and have not configured Eclipse to go around it. The link in the accepted answer did not work for me... found ones that did work though.
