title: "Cannot nest" error trying to integrate mopub + Eclipse
body: <p>Trying to integrate mopub but I get this error when I try to import the project:
  "Cannot nest 'mopub-sdk/src/main/java' inside 'mopub-sdk/src'. To enable the nesting exclude 'main/' from 'mopub-sdk/src'"</p>
  
  <p>Same error in a fresh workspace as well, so not sure what it could be. No help from mopub yet, and tried all versions of their sdk.</p>
  
  <p>Appreciate any advice, thanks.</p>
