Have you tried the alternative installation procedure (from a zip file)?

Here is the work around :

1. Separately download the jar files for which read timeout is hapenning. In this case download com.google.gwt.eclipse.sdkbundle.2.0.3_2.0.3.v201002191036.jar. com.google.appengine.eclipse.sdkbundle.1.3.3_1.3.3.v201004231111.jar. using above url.

   Note: both jars are above 80MB and takes a while for download.

2. copy the jars to plugin folder of eclipse

3. resume plugin installation once again.
