title: How to make a source attachement in eclipse?
body: <p>Background: I am trying to use google analytics api's for java, to make their simple "helloAnalyticsApi" java code. But, I cannot even get past the basic steps of setting up eclipse and such.</p>
  
  <p>Please see the link below:
  <a href="https://code.google.com/p/google-api-java-client/wiki/Setup#google-api-client" rel="nofollow">https://code.google.com/p/google-api-java-client/wiki/Setup#google-api-client</a></p>
  
  <p>In that link, they say:</p>
  
  <blockquote>
    <p>Blockquote 
    Eclipse users will want to set the "Source attachment" for each class jar to its corresponding "-sources" jar</p>
  </blockquote>
  
  <p>I dont know this means. Please tell me how to do what they say in the above sentence. 
  I tried a non-google tutorial, and it worked. But, when I try to make their sample java code, i get many errors which i mentioned in another post.</p>
  
  <p>Thanks.</p>
