While installing force.com IDE am getting this Error:
an arror occured while collecting items to be installed
please reply anybody with Right solution.
Looks like this is more of an Eclipse error it is not able to read some files from the repositories.
Hope this will help you.
This could be a problem with stale cached repository data. Please try again after deleting the p2/org.eclipse.equinox.p2.repository/cache directory from your STS installation. If that doesn't help, you could also try to change the repository URL from "dist.springsource.com..." to "download.springsource.com..."
Hope this will help you
