Unable to reserve cache with key Linux-sbt-cache-v2-..., another job may be creating this cache.

This is similar to #74, except related to the cache step (not the artifact upload/download step) which is used to cache maven dependencies between runs. Its keys will also need to be made unique.

Btw, unlike #74 I don't think this is harmful, just a missed cache/optimization opportunity.

Actually, my bad: apparently this step is really only intended to cache sbt itself, not the actual build dependencies. In which case the current key is fine (which afaict also excludes build.sbt).

But, it is still a missed opportunity to cache all the dependencies.
