title: Eclipse CDT: Class already exists (but doesn't)
body: <p>When I try to create a new Class using the CDT Eclipse "New C++ Class" Wizard, I get the error message "Class already exists".</p>
  
  <p>Fact is: a class with similar name existed in my project but the source files are definitely deleted. I now want to re-implement that class.</p>
  
  <p>My question is: Is there any way I can force Eclipse to update its "class cache" or whatever it is that keeps Eclipse from forgetting about this zombie class?</p>
