Agree, sounds like a good plan. I'm going to review and fix this in most 
popular cordova plugins and having this as an official recommendation I can 
refer to will be great (part of Android plugins dev guide).

PS. I've also double checked Cordova core plugins and they are not affected 
(there are actually not so much dependencies at all).

So, it seems like mechanisms are already in place to enable us to do what we 
wanna do here.

The actionable step I'm seeing here is 'updating the docs to ask plugin devs to 
use plugin.xml to define gradle dependencies'.

If you folks agree with what this actionable item, I will create a jira item to 
track it.

Thanks,

I thought we had a reference to a gradle file instead.
