title: Eclipse is telling me a cycle was detected in the building path, but that's not true!
body: <p>Eclipse is telling me:</p>
  
  <pre><code>a cycle was detected in the build path of -project name-
  </code></pre>
  
  <p>, although the structure of the project (created by others in the team) does not have cycles.<br>
  The same project is deployed on other machines (the same!) and it doesn't give the error. </p>
  
  <p>I need to work from my machine so I need to solve this.<br>
  It is giving me the error in 8 different projects.<br>
  It was giving me the error in more (10 projects) but with cleaning and building 10 times just changed to 8! (without any changes in the code). </p>
  
  <p>I really need to get this working and cleaning and building over and over is not doing anything. Any tips?</p>
  
  <p>(note: this is not java, this is flex so i can't change the error to warning :))</p>
  
  <p>Thanks a lot!</p>
