I have to develop an extension not same as org.eclipse.ui.actionSets, i
have to implement my functionality.
Functionality: If I select that extension while creating a plugin, it
allows to create a menu, and an action.
Example:
I created an extension point. I copied the content actionSets.exsd to the
newly created exsd file. Now the extension is displaying in list of
extension. I selected the newly creted extension and added menubar,
toolbar, an action.
Now I opened new instance of eclipse but it is not showing any menuitem or
toolbar
