It’s not just libraries though. All software needs to build when invoked with “buck build” and it’s dependencies need to be specified in buck’s configuration format. Scala’s build is different enough that it can’t piggyback off Java here. This requirement is a stumbling block for many languages. For example when compiling Rust, no one actually calls rustc directly, everyone uses cargo. Effectively this meant someone had to reimplement cargo within buck.
