Every current version of Scala runs on OpenJDK 11 or above. See:-
https://docs.scala.org/overviews/jdk-compatibility/overview.html
The only code that really needs to be in Debian for building anything scala related is sbt (which needs a current 2.12 to build), and that is the only bit of the scala infrastructure that is up to date (at 1.7.3 which is the latest version).
The scala compiler and other libraries currently on Debian are so out of date as to be of no use. Sbt downloads everything it and the project you are building including the compiler from Maven so having them in Debian is redundant.
The only sensible alternatives to sbt are mill (not currently in Debian) and gradle (which currently says it needs openjdk 8) which used for projects which are mixed java and scala.
