  <p>My first idea was that i made a mistake within the test, so i simplified the test run as much as possible:</p>
  
  <pre><code>import static org.junit.Assert.*;
  
  import org.junit.Test;
  import org.junit.runner.RunWith;
  
  import com.xtremelabs.robolectric.RobolectricTestRunner;
  
  @RunWith(RobolectricTestRunner.class)
  public class CommonDataTest {
  
      @Test
      public void test(){
          assertTrue(true);
      }
  
  }
  </code></pre>
  
  <p>but i still get the same error. I set up the Project as described here: <a href="http://robolectric.org/eclipse-quick-start/" rel="nofollow">http://robolectric.org/eclipse-quick-start/</a>
  The strange thing is that it worked with other Android Library Projects without any problems.</p>
  
  <p>Any help would be appreciated! Thank you in advance!</p>
