I'm trying to add a very simple action to the context menu of Eclipse: clicking with right button over a folder object, this action should call an external tool (configured in the "External Tools") using the path of the folder as the only parameter.
I've found a tutorial on how to add a context menu, but it's more complex than what I need -- I don't really want to create a plugin, I don't even want to create classes to do what I want. My only purpose is to call an external tool.
How can I do it?
