title: How to build a simple war file with sbt?
body: <p>I'm trying to make a webapp using Scala and Apache Wicket and am not sure how to structure my project and use SBT to build a war file.  What directory structure should I use and how can I have SBT build the war file?  </p>
  
  <p>I'm new to SBT but my guess is there is an SBT plugin I need for this, but I'm not sure which to use.</p>
