title: Running cucumber with activator
body: <p>I am new to cucumber and using it with sbt and Scala. I want to run the same with Lightbend activator. Is there any plugin available to run cucumber specifications through activator as well? e.g. To run the tests, I should run a command like: 
  <code>activator cucumber</code> instead of 
  <code>sbt cucumber</code>. 
  Please help. Thanks in advance! </p>
