   Am having trouble trying to download eclipse plugin using maven .
these are the steps i followed
 
1) viisited the link
http://docs.codehaus.org/display/MAVENUSER/Eclipse+Plugin
2) opened a cmd (in windows) and ran the 2nd command in the link page : 
   mvn eclipse:make-artifacts \
  -DeclipseDir=/path/to/eclipse/install \
