title: Android Eclipse - Cannot see annotation processing option
body: <p>I am unable to fine the option to set annotation processing in my Eclipse preferences. <img src="https://i.stack.imgur.com/cNzf4.png" alt="enter image description here"></p>
  
  <p>Not sure since when am I getting this problem but surely it has started to occur after I updated eclipse last. 
  I also tried pasting the annotations.jar file in tools/support folder but to no good. </p>
  
  <p>Kindly help.</p>
  
  <p>TIA</p>
