Eclipse RCP Plugin development - Can't get new menuContribution option

I am using Eclipse 3.2. For an RCP application, I am trying to extend from org.eclipse.ui.menus. When I right-click and pick new option, "menu Contribution" isn't appearing. I only see options 'item', 'menu', 'group', 'widget' under 'New'. There is no option named "menu Contribution". Am I missing anything in target platform? If so, which jar?

From stackoverflow

• Works for me using:
  Eclipse SDK
  Version: 3.4.1
  Build id: M20080911-1700
  I would suggest upgrading...3.2 is a little old IMHO

  

• I confirm it can not work.

  Consider the Extension Points Reference help from:

  • org.eclipse.ui.menus in 3.2.1

    <!ELEMENT extension (item* , menu* , group* , widget*)>

  • org.eclipse.ui.menus in 3.4 Ganymede

    <!ELEMENT extension (group* , widget* , menuContribution*)>

  That is why you do not see menuContribution
