Be able to get a snapshot corresponding to any branch

This seems it's required to be able to resolve the branch name through the version name to be able to build it if it's not done.

possible approach:

• use a sysmetric transformation (almost impossible)
• store association in db
• push a file named "artifact.branch" descriptor in the release hierarchy once the branch is created
  I like the last one - it does not require any access to db or git to know if a build is required and to get the branch on which the build must be done
