title: google-api-client-java eclipse build path and google app engine
body: <p>I am trying to follow the instructions here:</p>
  
  <p><a href="http://android-developers.blogspot.ca/2013/01/verifying-back-end-calls-from-android.html" rel="nofollow">http://android-developers.blogspot.ca/2013/01/verifying-back-end-calls-from-android.html</a></p>
  
  <p>I have decided to download the google-api-java-client library and see if I can instantiate the code on the bottom half of the page referenced above. I have imported libraries in eclipse in my app engine project so that eclipse doesn't complain about anything BUT when I try this:</p>
  
  <pre><code>    GoogleIdToken token = GoogleIdToken.parse(mJFactory, tokenString);
  </code></pre>
  
  <p>eclipse complains with red underlining on 'GoogleIdToken.parse()' and this text</p>
  
  <blockquote>
    <p>The project was not built since its build path is incomplete. Cannot find the class file for com.google.api.client.auth.jsontoken.JsonWebSignature. Fix the build path then try building this project</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>The type com.google.api.client.auth.jsontoken.JsonWebSignature cannot be resolved. It is indirectly referenced from required .class files </p>
  </blockquote>
  
  <p>I have gone to this site and have followed the instructions as closely as I can, but the error remains.</p>

  <p>can anyone tell me how to get rid of this error?</p>
