title: Android Studio release build does not output aar
body: <p>I have create a very simple 'Android Library' module with only one class which builds fine in debug releasing build/output/library-debug.aar</p>
  
  <p>But, when I switch to release, even though it says build successful, the aar is not there.</p>
  
  <p>The Android Studio project only has this library module.</p>
  
  <p>Thanks for advance.</p>
