title: Cannot find symbol class Bind of butterknife
body: <p>Somehow I have a mistake in my gradle build. Somehow I cannot find the class Bind of butterknife.</p>
  
  <p>It is probably due to my gradle, but I do not know.</p>
  
  <p>I get this error:</p>
  
  <blockquote>
    <p>Error:(40, 6) error: cannot find symbol class Bind</p>
