title: Android gradle disable removing resources without default value
body: <p>Since upgrading to Android Gradle Plugin 3.2, resources without required default values are removed. Causing the build to fail.</p>
  
  <pre><code>Execution failed for task ':app:processDebugResources'.
  &gt; Android resource linking failed
    warn: removing resource my.package.name:string/my_string_resource without required default value.
    /path/to/layout.xml: AAPT: error: resource string/my_string_resource (aka my.package.name:string/my_string_resource) not found
  </code></pre>
  
  <p>Can this be disabled? I'm currently using the latest Android Gradle Plugin: 3.4.0</p>
  
  <p>We need that because our customer's translation process requires us to deliver test-builds of the app in another language than the default language. Default values have to be omitted so that translators can easily see what still needs to be translated.</p>
