title: Gradle build: Execution failed for task ':app:lint'
body: <p>I'm using Android Studio 2.0 and I was trying to running my program when something strange happened. I ran the build command of the gradle and I got this error:</p>
  
  <pre><code>FAILURE: Build failed with an exception.
  
  * What went wrong:
  Execution failed for task ':app:lint'.
  &gt; Lint found errors in the project; aborting build.
  
  Fix the issues identified by lint, or add the following to your build script to proceed with errors:
  ...
  android {
      lintOptions {
          abortOnError false
      }
  }
  ...
  
  * Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

  <p>And so... What the hell is that? I'm supposed to do to solve this problem adding the code to the gradle.build, but the question is: <strong>why I got this error message?</strong></p>
  
  <p>Please save me guys!</p>
