title: vaadin10.Session plugin location
body: <p>I'm new to web development. In some VaadinOnKotlin examples I see this code</p>
  <pre><code>import eu.vaadinonkotlin.vaadin8.Session
  </code></pre>
  <p>This is resolved by:</p>
  <pre><code>plugins {
      id(&quot;com.vaadin&quot;) version &quot;0.8.0&quot;
  }
  </code></pre>
  <p>In other examples I see this code:</p>
  <pre><code>import eu.vaadinonkotlin.vaadin10.Session
  </code></pre>
  <p>How does this get resolved? In <a href="https://jcenter.bintray.com/eu/vaadinonkotlin/" rel="nofollow noreferrer">https://jcenter.bintray.com/eu/vaadinonkotlin/</a> I don't see any entries for vaadin10</p>
