-# This script runs the following workflow:
-#
-# 1. Generate the dependency lock file.
-# 2. Run a build against the generated lock file and save the lock file if the
-#    build succeeds.
-# 3. Upload dependency JARs to a private Maven repository.
-# 4. Generate the metadata file for each third party dependency and
-#    publish the file to a Git-on-Borg repo where the Vomit system can scan.
