I want to use vaadin 7. While downloading latest vaadin plugin for eclipse, I am getting 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=).
No repository found containing: osgi.bundle,org.apache.ivy,2.3.0.cr2_20121105223351
No repository found containing: osgi.bundle,org.apache.ivyde.eclipse,2.2.0.beta1-201203282058-RELEASE
Your error sounds a bit like a (temporary) connection problem. Please try again, possibly restart Eclipse. If it doesn’t go away, it could be something else.
I resolved this issue by manually downloaded the .jar file from the error result url “http://vaadin.com/eclipse/plugins/com.vaadin.wysiwyg.eclipse_2.1.1.201302181316.jar” . Just copy the url and paste into the browser, save the .jar file into Eclipse/plugins directory . Then try to install vaadin 7 plugin again and hope this time it will be resolved, It worked for me.
