Firebase SDK 9.0.0 is exciting but I cannot find the plain java version of its library. The older 2.5.2 doc used to have separate SDK for Android and plain JVM, I cannot find this information in the new doc.
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?
