title: gradle: Exclude all - except one file
body: <p>In a gradle build I would like to exclude all files except one. I tried to do it like this:</p>
  
  <pre><code>processResources {
  
      // exclude everything
      exclude '*.*'
  
      // except this file
      include 'fileA.xml'
  }
  </code></pre>
  
  <p>..but it does not seem to work - all files are excluded. Is this possible in some way?</p>
  
  <p>Thanks for your help and input.</p>
