title: object compress is not a member of package org.apache.commons
body: <p>I've been trying to use the apache commons.
  But, it fails and get the following errors.
  I've no idea how to fix it. Maybe, need to add something into build.sbt?</p>
  
  <pre><code>$ sbt
  &gt; clean
  &gt; compile
  [error] hw.scala:3: object compress is not a member of package org.apache.commons
