title: Cordova-android how to edit the project.properties file generated when adding a platform
body: <p>So when adding my android platform using <code>cordova add platform android</code> the folder that it generates creates a <code>project.properties</code> file.</p>
  <p>This file (in my project) has the following line:</p>
  <pre><code>cordova.system.library.15=androidx.appcompat:appcompat:1.+
  </code></pre>
  <p>Now due to a new release (<code>1.4</code> beta) this causes my build to fail.</p>
  <p>So I would like to edit this file and add a specific version number.</p>
  <p>However since I am using a build server I really want this to happen as soon as I run the command <code>cordova platform add android</code></p>
  <p>Where can I change these settings?</p>
