title: Error: Execution failed for task ':app:javaPreCompileDebug'. > java.io.IOException: Failed to delete annotationProcessors.json
body: <p>I am trying to code in <code>Kotlin</code> in Android Studio 3.0 Canary 2. When I make changes in the code then I have to rebuild the complete application from Build -> Rebuild Project then Run</p>
  
  <p>After making changes in code, simply when I click on run button then it shows this error randomly.</p>

  <p>What could be the issue ? It seems issue with build-tools or <code>Kotlin</code> compiler as it works fine with <code>Java</code>.</p>
