title: Android Studio: Failed to create MD5 HashFile
body: <p>I am creating a simple android application... I ran into some kind of trouble when I updated gradle when I launched Android Studio and it prompted me too.</p>
  
  <p>Upon the update completing I receive the following error:</p>
  
  <p>Error:Execution failed for task ':app:compileDebugJavaWithJavac'.</p>
  
  <blockquote>
    <p>Failed to create MD5 hash for file '/Users/damenTomassi/AndroidStudioProjects/AstraeaDemo/app/src/main/res/libs/gson-2.3.1.jar'.</p>
  </blockquote>
  
  <p>I used to have the GSON library in my project, however I no longer needed it so I removed it... </p>
  
  <p>Does anyone have any suggestions?</p>
