eclipse - How to add items in popup menu?

In eclipse plugin development, I want to add one item (eg: Mystyle ) in popup menu.

For an instance,

Project Explorer --> Right Click --> New --> MyStyle

How can I achieve this in eclipse plugin development?

Something like this should do it (following this thread):

   <extension
         point="org.eclipse.ui.menus">
      <menuContribution
         locationURI=
         "popup:org.eclipse.ui.navigator.ProjectExplorer#PopupMenu?after=additions">
         <command
               commandId="myplugin.command.mycommand"
               icon="icons/etool16/mycommand.png"
               label="Run mycommand"
               mnemonic="M1+P"
               tooltip="Do something with this project">
         </command>
      </menuContribution>
   </extension>

See Menucontribution

Defines an ordered set of additions to the command UI structure. The defined elements will be added into the command UI structure at the location specified by the locationURI element.

This should be the starting point for all contributions into menus, toolbars or trim, wherever they occur in the UI.

• locationURI - A URI specification that defines the insertion point at which the contained additions will be added.
  The format for the URI is comprised of three basic parts:
  • Scheme: One of "menu", "popup" or "toolbar.
    Indicates the type of the manager used to handle the contributions
  • Id: This is either the id of an existing menu, a view id or the id of the editor 'type'
  • Query: The query format is <placement>=<id> where: <placement> is either "before" or "after" and <id> is the id of an existing menu item

See also org.eclipse.ui.popupMenus, org.eclipse.ui.menus-extension point with a menuContribution that has its locationURI-attribute pointing to popup:org.eclipse.ui.popup.any?after=additions.
Warning, as Prashant Bhate mentions in the comment, that package org.eclipse.ui.popupMenus is deprecated.
