Interesting. In Gerrit we extended Buck to have a maven_jar() rule
that knows how to acquire a JAR from Maven:

  name = 'gson',
  id = '',
  sha1 = '2e66da15851f9f5b5079228f856c2f090ba98c38',
  license = 'Apache2.0',

It downloads the JAR from the Maven repository, and verifies the SHA-1
before allowing it as an input into the build. Not as "git friendly"
as mdm, but its still effective at ensuring the build runs with the
correct input.

The maven_jar() rule caches the downloaded files into
~/.gerritcodereview/buck-cache allowing you to rerun builds from a
clean environment without touching the network. And
tools/ does a fetch of every network JAR into the
cache, making it easy to get an environment setup from nothing and
able to work without network access.
