I've decided that as a pet project meant for learning, I would create a new Eclipse plug-in that, for a given class, takes all private member names and adds a prefix to their name (it doesn't matter to me if it can already be done or not, this is meant to be a learning experience).

I have never developed an Eclipse plug-in and I'm not sure where to begin. Do I need to install some application for this development? How does it work? Where do I begin?

I did a Google search but all the tutorials and results I found were old and referred to antiquated versions of Eclipse, so I'm not sure if they're still accurate.
