title: ClassNotFoundException when running a junit test in eclipse
body: <p>I am really desperate why this exception can even occurs ? I am running test in class  <code>MyTestIT</code>. And what class is not found ? Class which I run... I tried to clean and build it again in eclipse but with no success</p>
  
  <pre><code> Class not found it.mytest.MyTestIT
      java.lang.ClassNotFoundException: it.mytest.MyTestIT

  <p>PS: I forgot to add it was working whole time. But today I just turn on eclipse and I cant run test here. With maven it is still working</p>
