Can't install blackberry webbook plugin in eclipse

using http://www.blackberry.com/go/eclipseUpdate/3.6/java i installed Blackberry Java plugin (core), Blackberry java SDK but for using phonegap i used that as link

http://wiki.phonegap.com/w/page/31930982/Getting%20Started%20with%20PhoneGap%20BlackBerry%20WebWorks

I tried http://www.blackberry.com/go/eclipseUpdate/3.6/web to get Blackberry webworks plugin, webworks SDK but was not successful, it gave an error

The installation could not be completed due to a conflicting dependency.
