title: add cordova plugin dependency to build.gradle
body: <p>I searched extensively but cannot not find the maven repository for org.apache.cordova.
  I want to edit an existing plugin (from github) in android studio. </p>
  
  <p>I have tried adding the dependency by jar file. But generating the jar fails when "ant jar" with complex errors (cannot find symbols, pointing at the imports). </p>
  
  <p>Thanks for help 
  Greetings
  Felix</p>
