title: What does "Refresh resources upon completion" do exactly?
body: <p>I have been searching for a while online, since I don't exactly understand what "refresh resources" exactly mean? What are exactly "resources" in this case, and what does selecting that check box do (Refresh resources upon completion)?
  I know when you build your project, your source files gets compiled and dependencies gets downloaded/installed into the local machine .m2 repository, if they need to. But I don't know what does "refreshing resources" in this case mean. What does it do exactly? I am not sure what does the "refresh" (when you right click a project and say "refresh") do either? Are they the same?</p>
  
  <p>Thanks,</p>
