Buck requires explicit declaration of dependencies and enforces that by use of a symbolic link tree. Since all dependencies are explicit and Buck has a directed acyclic graph of all source files and build targets, Buck can perform incremental recompilation only building targets downstream of files that have changed. Buck computes a key for each target that is a hash of the contents all the files it depends on. It stores a mapping from that key to the built target in a build cache. Assuming that all targets are deterministic functions of the contents of their dependencies you can share this build cache between developers and continuous integration (CI) as Buck supports a HTTP Cache API.
