title: Gradle 4.7 targetCompatibility for JDK 10
body: <p>Anybody know what targetCompatibility value to use for JDK 10? Supposedly Gradle 4.7 supports it.</p>
  
  <p>e: Currently using <code>1.10</code> but I can't find any confirmation that this is correct. <code>java --version</code> reports <code>10.x</code> instead of the usual <code>1.x.x</code> format.</p>
