Authors and runs Liquibase database migrations - changelog-driven schema management with changesets in XML / YAML / JSON / SQL formats; supports `liquibase update` / `status` / `rollback` / `tag` / `history` lifecycle; offers per-changeset preconditions, contexts and labels for selective execution, and rollback semantics; tracks state in `DATABASECHANGELOG` + `DATABASECHANGELOGLOCK` tables. Use when the user works with Liquibase-managed schemas (Spring Boot heritage, polyglot DB shops), needs…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# liquibase-migrations ## Overview Per [github.com/liquibase/liquibase][lb-gh]: [lb-gh]: https://github.com/liquibase/liquibase > "Liquibase helps millions of developers track, version, and > deploy database schema changes." Liquibase's distinguishing feature vs Flyway: changesets are **format-portable** (XML / YAML / JSON / SQL) and **rollback-aware** - each changeset declares its own rollback action, enabling deterministic per-changeset rollback rather than versioned-only migration replay. State tracked in two tables (per Liquibase docs): - `DATABASECHANGELOG` - applied changeset history (id + author + filename + dateExecuted + checksum) - `DATABASECHANGELOGLOCK` - distributed lock to serialize concurrent `update` runs ## When to use - The repo has `db.changelog-master.xml` / `.yaml` / `.json`. - The user works with Spring Boot Liquibase auto-config or any of the Liquibase Maven / Gradle / Ant plugins. - The team needs cross-DBMS portable migrations (XML/YAML changesets translate to per-DBMS SQL at apply time). - Per-changeset rollback support is required (vs Flyway's whole-version rollback). ## Step 1 - Install Per [lb-gh][lb-gh] the documented quickstart: …

How to install
mdr add testland/qa/liquibase-migrations@sha256:4d1975cac80ec177The line at the top of this page pins the label git:20261002.6a3229d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
