title: Travis CI build failed
body: <p>I'm trying to integrate Travis CI with my GitHub project. I managed to configure Travis plugin successfully with my repository by following <a href="https://travis-ci.org/getting_started" rel="nofollow noreferrer">Travis getting Started Guide</a></p>
  
  <p>But when i pushed my first commit after integrating Travis ,it is giving me this error when it auto builds.</p>
  
  <pre><code>/home/travis/build.sh: line 179: ./gradlew: Permission denied
  The command "eval ./gradlew assemble" failed. Retrying, 2 of 3.
  </code></pre>
  
  <p>Below is a screenshot of the Travis build :
