Maven tag

Last updated: August 12, 2026

The Maven tag goal marks the current database state so you can roll back or deploy changes in the future.

Uses

The Maven tag goal is typically used to mark the current database state by adding the tag to the last row of the DATABASECHANGELOG table.

Liquibase tag operations

When you run the tag goal and use the tagDatabase Change Type in your changelog file, and they do not match each other, you will have the following:

  • If this is the first row in the DATABASECHANGELOG table, a Liquibase internal row is added to the DATABASECHANGELOG table with the tag name specified when you ran the tag goal with the liquibase.tag attribute.

  • If this is not the first row in the DATABASECHANGELOG table, the last row in the DATABASECHANGELOG table is updated to include the tag name specified when you ran the tag goal with the liquibase.tag attribute.

  • If this is not the first row in the DATABASECHANGELOG table and the last row in the DATABASECHANGELOG table already has a tag, a new tagDatabase row is added to the DATABASECHANGELOG table.

Liquibase update to tag operations

If you want to make an update to a specific tag using the liquibase.toTag attribute, it will work only if there is a tagDatabase Change Type in the changelog:

  • When a Liquibase tagDatabase When a changeset is deployed from the changelog, it adds a new row to the DATABASECHANGELOG table, which will have the tag name specified in the changeset.

  • When liquibase.toTag is configured, and there is a row in the DATABASECHANGELOG table corresponding to the tagDatabase changeset in the changelog, the update goal deploys all objects up to and including the tagDatabase changeset.

  • When liquibase.toTag is configured, and there is no matching tagDatabase changeset specified in the changelog, the update goal deploys all changesets that are not excluded by labels, contexts, dbms, and others.

Liquibase rollback by tag operations

When a Liquibase tag changeset is deployed from the changelog and the liquibase.rollbackTag attribute is configured with a value matching the tag in the changeset, the rollback goal removes all changes that come after the tag changeset. It also rolls back the tag changeset.

When you run liquibase.rollbackTag with the tag specified only by using the tag goal with the liquibase.tag attribute, the rollback command will revert all your changesets after the tag you specify.

Note: It is best practice to tag your changesets before running any other commands against your database.

Maven configuration

You can configure Liquibase Maven in multiple ways. You can pass arguments like <changeLogFile> in Maven directly in your pom.xml file, in a liquibase.properties file referenced in your POM, as environment variables, or as JVM system properties. To learn about each files syntax, see Maven Properties.

For more information about the Maven configuration, see Configuring Maven.

Additionally, you can include <liquibase.tag>specify your tag here</liquibase.tag> in your pom.xml file under the <properties></properties> in the <project></project> level.
