title: Eclipse does not show src file
body: <p>I have three different projects in my eclipse and yesterday src file became unvisible in one of the projects. Two days ago it was ok and I have no idea how this happened. I can not see src file in project explorer or package explorer.</p>
  
  <p>Project Explorer :</p>
  
  <p><img src="https://i.stack.imgur.com/bjM9K.png" alt="Project Explorer"></p>
  
  <p>However, if I look with navigator I can see all files in the directories.</p>
  
  <p>Navigator :</p>

  <p>I use Eclipse Indigo SR2 and IBM Rational ClearCase for first two project. The other is my local test project.</p>
  
  <p>Do anybody know how can I get back to src file into the project explorer?</p>
  
  <p>Thanks.</p>
