update-build-files

pants update-build-files [args]

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 https://www.pantsbuild.org/2.20/docs/releases/upgrade-tips for upgrade tips.

This goal is run without arguments. It will run over all BUILD files in your project.

Backend: pants.core

Config section: [update-build-files]
