Couldn't install google extenstion on STS-2-7-0-M2

[Dawit]

I am not able to install the google extension on my STS (version 2.7.0.M2). Here is the exception that I am getting. Any help would be appreciated.

An error occurred while collecting items to be installed

Hey!

I tried this a minute ago to check what might be going wrong here, but the download and the installation works now again. Maybe a download/proxy problem that extracts/re-packs the downloaded jar files?

HTH,
Martin

Thanks Martin,
That was (proxy) indeed the problem.
