Actually, I take that back. https://alvinalexander.com/scala/setting-putting-sbt-into-offline-mode-no-wifi/
Seems there is an "offline" option for sbt. The use case is for working on airplanes, so not an air-gapped environment, just an environment with intermittent connectivity to the internet. But still this may help. One still needs an internet connection to discover and cache all the necessary dependencies of sbt versions. But then one should be able to copy the ".ivy2" cache to an air-gapped system, and then use sbt there with offline mode.
