title: Add files to Gradle sourceSets in Kotlin DSL
body: <p>I have started using Kotlin DSL in my Gradle builds. Before I could write the following in Groovy DSL:</p>
  
  <pre><code>sourceSets.main.resources.srcDirs("src/main/resources").includes.addAll(["**/*.*"])
  </code></pre>
  
  <p>How can I write this in Kotlin DSL?</p>
