title: Where is the location of 'plugins' directory for eclipse mars in mac OSX?
body: <p>I was trying to install the eclipse plug-in for an assignment.
  But the problem is, my installed eclipse's version is mars, which means I can not find the location of the 'plugins' directory, which was used to save plug-in jar files.</p>
  
  <p>I've updated the eclipse Luna to Mars recently.
  When I installed(unzipped) the eclipse luna, I remember that there was 'plugins' directory and other things (including eclipse.app) were in the 'eclipse' directory.
  However, The mars, archive file just gives me an eclipse.app!..</p>
  
  <p>Could you tell me how to add the plugin(*.jar, in my case, UMLet) to eclipse mars on Mac OSX?
  I have to do my assignment.. The due is coming..</p>
