Error installing Vaadin plugin in eclipse juno

Hi 

Hi, i'm trying to install the eclipse plugin for Eclipse Juno SR2 win32-x86_64 from eclipse marketplace and got the following error :

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=).

What am I missing out? would appreciate any leads.
 

Hi,

Might be a network error (or a proxy?) or some missconfiguration of the update sites. I'd try accessing those URLs manually to discard network/proxy issues. If that's not the problem, I'd try with a "fresh" Eclipse for Java EE developers installation. Maybe unchecking the contact all update sites during install to find required software option might help, but I'm just guessing now.
