We followed the instructions from
http://code.google.com/appengine/docs/java/gettingstarted/installing.html
to install the Google Plugin for Eclipse, for Eclipse 3.6 (Helios).
After 28% of installation we got an error :
An error occurred while collecting items to be installed
session context was:(profile=epp.package.java,
phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=,
action=).

We have jdk 1.7 version and one of among us could successfully install
but we could'nt add web tools for the plugin.
Could you please suggest a remedy for this.
