title: Copy all jars from subprojects to root project’s bin directory
body: <p>I'd like to copy every jar generated from subprojects from their <code>/bin/libs</code> dir to the root project's <code>bin</code> dir. Unfortunately, my current code just copies <strong>everything</strong> from the subprojects into that directory:</p>
  
  <pre><code>task muleapp(type: Copy) {
      from '.'
      include '**/bin/libs/*.jar'
      into 'bin'
  }
  </code></pre>
  
  <p>How can I achieve the desired functionality?</p>
