title: What is Eclipse doing when it says that it's updating indexes?
body: <p>When I load up a workspace (for Android Java development), Eclipse says in the status bar that it's updating indexes.  The Progress tab reports that it's hitting maven.org.</p>
  
  <p>I read up on Maven - seems like a build manager.  What I don't understand is why my Android workspace needs it or why it's hitting the server in the cloud.  Do I need it?  If not, how do I safely remove it?</p>
