Trying to install new features in Eclipse (using ADT as the base package)

Question

When I try to install new features in Eclipse (using ADT as the base package) I get

‘Installing Software’ has encountered a problem.
An error occurred while col         


        

Answer 1

Brilliant, I was on version 21.0.1 and my Tools were on 21.1 for some reason and changing from http to https, i.e. https://dl-ssl.google.com/android/eclipse/ seemed to work and ADT downloaded and updated.

On starting Eclipse there was no error message.

Sadly, on getting to the workspace what has happened is:

1. All my toolbar and menu shortcuts (except help/about) for ADT have been wiped
2. All my sites in the 'available' sites have been wiped
3. In general my Eclipse is now shagged

Well done Eclipse the plug-in nightmare system you've created has ruined yet another installation of mine. That's, like every instance I've ever had fails when I dare to install or use a plugin.
