title: How to open a eclipse java and a c++ project point to the same root directory
body: <p>I have a directory which has both java/c++ code (they are in different sub-directories, multiple of them). How to open a eclipse java and a c++ project point to the same root directory? eclipse won't let me, saying something like 'there is a project exists in the same location'</p>
  
  <p>Thank you.</p>
