I’ve spent some time thinking about named resolves, the first part of which involve us somewhat inverting the way we approach lockfiles. Current we do this: 1. Write JVM artifacts 2. Add those artifacts as requirements to the lockfile 3. Resolve artifacts and their dependencies and write to the lockfile 4. Supply the lockfile as a dependency to the Java Sources AIUI, we need to change it so that the 

coursier_lockfile

 target does not have requirements, but instead, we infer those requirements based on the artifacts that are dependencies (inferred or otherwise) of 

java_source

 targets that depend on the lockfile. That needs dependency inference over 3rd party dependencies (and potentially having those present before a lockfile is ready) Is dependency inference at a stage where we can look into dependency JAR files to see if a dependency is present? (ping @fast-nail-55400)
