title: How to reproduce bin folder in Eclipse after it is deleted?
body: <p>I'm switching out of Net Beans (since Netbeans intellisense speed was too fast for my patience). However, my habit since NetBeans age driving me nut with new Eclipse.
  Normally, when some thing is wrong inside Netbeans auto compile mechanism, I just go to build folder located under the project root and delete it (sometimes with Unlocker), then Net Beans will recreated that folder and put .class file into. However, recently, when I tried to do the same thing with bin folder under Eclipse project root, the bin folder will not be reproduced, even if I restart the IDE, turn off Build Automatically, and run Build All (Ctrl+B).</p>
