title: Firebase SDK 9.0.0 plain java version?
body: <p>Firebase SDK 9.0.0 is exciting but I cannot find the plain java version of its library. The <a href="https://www.firebase.com/docs/android/quickstart.html" rel="nofollow">older 2.5.2 doc</a> used to have separate SDK for Android and plain JVM, I cannot find this information in the <a href="https://firebase.google.com/docs/android/setup" rel="nofollow">new doc</a>.</p>
  
  <p>Is there a way to use this SDK for non-Android project, like say, JavaFX? If not, will I run into a problem for still using the older 2.5.2 SDK on my JavaFX project?</p>
