I tried to do a Help => Software Update => Find and Install and got:
-----------------------------------------
Requested operation cannot be performed because it would invalidate the
current configuration. See details for more information.
Platform configuration has been modified outside this program. A
restart is recommended.
-----------------------------------------
Though I have no idea, who or what could cause this (I haven't touched
my eclipse configuration in at least 2 months...) I restarted eclipse as
recommendd and then tried again, but same result.
How can I kick eclipse to refresh or adopt the current configuration so
I can have a check what's new?
