title: How to initialize kotlin spring project using gradle with groovy
body: <p>I'm learning spring with <code>kotlin</code>, and have some projects with it, but, my gradle scripts are always generated using kotlin dsl, I want to use groovy for them. <em>(Find info for kotlin dsl is a bit hard for me.)</em></p>
  <p>Can someone help me? I already try to use <code>start.spring.io</code>, spring tool suite. Also I try to make it by hand using <code>gradle init</code></p>
