title: Is it possible to ignore the storeFile when building a debug version of the application?
body: <p>The crux of the issue is that not everyone working on this application has access to the storefile, and has to comment out these lines as followed in order to make a gradle sync:</p>
  
  <pre><code>signingConfigs {
      release {
  //        storeFile file('.../android_keystore.keystore')
  //        storePassword RELEASE_STORE_PASSWORD
  //        keyAlias RELEASE_KEY_ALIAS
  //        keyPassword RELEASE_KEY_PASSWORD
      }
  }
  </code></pre>
  
  <p>In our build types, we defined that there is no signingconfig in debug:</p>
  
  <pre><code>buildTypes{
       release {
            ...
       }
       debug {
            singingConfig null
            ...
       }
  }
  </code></pre>
  
  <p>The problem is that Gradle Syncs are agnostic to the build type, therefore it checks for the signing configs (storePassword, keyAlias, keyPassword) every time unless I comment those lines out.</p>
  
  <p>Is there a more automated way to ignore these lines?</p>
