title: Specify different repositories when using Cordova gradle wrapper
body: <p>I'm using Cordova Android 4.0.0 which uses a gradle wrapper to build.  I need to specify a different repository than mavenCentral.  I can't simply modify the build.gradle file because it's auto-generated by Cordova.  Because it's using the wrapper distribution specified by Cordova I can't add an /init.d to the distribution.  I've tried adding a USER_HOME/.gradle/init.gradle file which doesn't seem to be getting used.  Is there some other way to specify an init file when using a wrapper that I don't have control over? </p>
  
  <p>EDIT:
  As a workaround for now I've added an after_prepare hook that changes the text "mavenCentral()" found anywhere in the build.gradle files to the repo I need to use instead.  There's got to be a better gradle based solution though...</p>
