Linter that validates the Liquibase migrations file against a spec. This lets us check and enforce additional constraints for the 000_migrations.yaml file (e.g. make sure you're not using duplicate migration IDs, or including more than one change in a single changeSet).

Older/existing migrations are validated with a less-strict spec; newer ones use a stricter spec that enforces some additional constraints. Migrations 172 and newer use the stricter spec. The less-strict specs are in x.unstrict namespaces while equivalent stricter ones are in x.strict namespaces.

Run the linter with

./bin/lint-migrations-file.sh

Add some tests for the checks you add here the test/ directory; run them with

cd bin/lint-migrations-file
clojure -M:test
