Do you have problems updating the ADT for Eclipse (Android Development Tools), for example from version 12 to 14, and get an error similar to this:
An error occurred while collecting items to be installed session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=). No repository found containing: osgi.bundle,javax.xml.bind, 2.0.0.v20080604-1500 ...
You might try the following: Disable all other update sites and try installing again. You can do this in Window -> Preferences -> Install/Update -> Available Software Sites. Then go to Help -> Install New Software… again and select to work with “ADT Plugin – https://dl-ssl.google.com/android/eclipse/”.
In our case it worked (Eclipse Indigo 3.7 on Windows 7)! The hint came from this thread.
