title: Large build time using Android Studio 3.1
body: <p>I am using android studio v 3.1. Operating System - Windows 10. Core i5 with 16 GB ram.
  Below is the result of build profiling</p>
  
  <pre><code>:app:transformClassesWithDesugarForDevelopmentQuickbuild 35.137s
  
  :app:compileDevelopmentQuickbuildJavaWithJavac 31.917s
  
  :app:transformClassesWithDexBuilderForDevelopmentQuickbuild 28.579s
  
  :app:compileDevelopmentQuickbuildKotlin 20.145s
  
  :app:transformClassesWithMultidexlistForDevelopmentQuickbuild 16.873s
  
  :app:mergeDevelopmentQuickbuildResources 16.363s
  
  :app:transformResourcesWithMergeJavaResForDevelopmentQuickbuild 7.958s
  
  :app:transformNativeLibsWithMergeJniLibsForDevelopmentQuickbuild 6.483s
  
  :app:processDevelopmentQuickbuildResources 4.835s
  </code></pre>
  
  <p>Projects gradle.properties has below configuration</p>
  
  <pre><code>org.gradle.parallel=true
  org.gradle.configureondemand=true
  org.gradle.daemon=true
  android.enableBuildCache=true
  kotlin.incremental=true
  </code></pre>
  
  <p>still for any single line of change build takes at least 2.3 minutes. This problem occurs only in windows and on ubuntu same configuration takes 15-20 seconds. 
  What else can be done to reduce build time?</p>
