title: SBT: view class file summary during compilation?
body: <p>Trying to see exactly what source files are being compiled during full &amp; incremental builds.</p>
  
  <p>As it stands I see a summary a la "X number of Scala and Y number of Java files" being compiled, which is great, but <em>exactly which</em> files are being compiled?</p>
  
  <pre><code>set logLevel in Global := Level.Debug
  </code></pre>
  
  <p>does nothing useful (that I can see)</p>
  
  <pre><code>set scalacOptions in Compile += "-print"
  </code></pre>
  
  <p>is more helpful, it prints out the internet...I mean, tons of generated code, which does contain the class names, just not so easy to sift through.</p>
  
  <p>Basically looking to get a summary of files being compiled.</p>
  
  <p>Perhaps there's a non-verbose option to the above scalac flag?</p>
