Hi, sbt was removed in 2023 (https://bugs.debian.org/1035929). These packages existed only for it and are built for Scala 2.11; half of them fail to build with scala 2.12 (https://salsa.debian.org/java-team/scala/-/merge_requests/2):
sbt-ivy, sbt-serialization, sbt-launcher-interface, scala-pickling, jawn, json4s, scopt, scala-tools-sbinary and, once their users have moved to the new -2.12 packages: scala-xml, scala-parser-combinators Nothing else depends on them. If nobody objects within a week, I will file the RoQA removal bugs. Juan
