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 collecting items to be installed
An error occurred while collecting items to be installed
session context was:(profile=profile, hase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).  No repository found containing: osgi.bundle,com.android.ide.eclipse.base,21.1.0.v201302060044-569685

I have installed a number of addons and I’m not sure which one might be giving the error. If anyone else has faced this error and found a solution, that would be great. Thanks.

Answer 1

Try changing the address of the repo from http to https or vice versa

Answer 2

This worked for me:

In Eclipse, try:

Help > Install New Software

Choose "Work with: https://dl-ssl.google.com/android/eclipse/"

Select the updates to install and uncheck "Contact all update sites during install to find required software"
