title: Eclipse confusing package to be a folder
body: <p>I have read some questions on this around here but my tries at the answer have not yielded success. Here is the problem:
  <br></p>
  
  <ul>
  <li>Package:com.me.a
  <ul>
  <li>Folder(under above package):b
  <ul>
  <li>Java class(under above folder):Myclass.java</li>
  </ul></li>
  </ul></li>
  </ul>
  
  <p>The proper package structure is com.me.a.b, but eclipse thinks 'b' is a folder. When I right click on b and go to build-source, there is an option that says "use as source folder" which then does something totally unwanted - creates a separate folder with the entire package path as a source folder, and uses a default package:
  <br></p>
  
  <ul>
  <li>Folder: com.me.a.b
  <ul>
  <li>Package: default package
  <ul>
  <li>MyClass.java</li>
  </ul></li>
  </ul></li>
  </ul>
  
  <p>How do I solve this annoying issue? </p>
  
  <p>PS: I am unable to use images which to give a better idea but being new here, there is a restriction.</p>
