update-build-files

﻿
Format and fix safe deprecations in BUILD files.
This does not handle the full Pants upgrade. You must still manually change `pants_version` in `pants.toml` and you may need to manually address some deprecations. See [Upgrade tips](🔗﻿) for upgrade tips.
This goal is run without arguments. It will run over all BUILD files in your project.

Format BUILD files using Black.
