title: Android gradle project directory variable
body: <p>I am trying to write a script in gradle that requires opening up a file. I am trying to find the current directory where the project is installed. so I can open a file in my "raw" directory.</p>
  
  <p>Note: I am aware that I can use a temporary file to find the current location of the application. However, I am trying to stay away from that solution.</p>
  
  <p>I am trying to find out if gradle has a buildDir variable that I can use in my task instead.</p>
