title: Android DataBinding increases Compilation time
body: <p>After using DataBinding in my project, it increases the compilation time by almost 3 time.</p>
  
  <p>Anyone experienced this issue and any one have solution to this issue</p>
  
  <p>android {
      ....
      dataBinding {
          enabled = true
      }
  }</p>
  
  <p>here is the Gradle Process,</p>
  
  <p>Gradle console output should be something like this (produced also without Data Binding dependency), where most tasks show "UP-TO-DATE":</p>
  
  <p>Executing tasks: [:app:assembleDebug]</p>
  
  <p>Configuration on demand is an incubating feature.:app:preBuild UP-TO-DATE
