Maven changelogSyncToTag

The changelogSyncToTag goal marks all undeployed changesets from your changelog up to the specified tag as executed in your database. The goal also marks the changeset with that tag as deployed.

Note: If you don’t have any tag specified in your changelog file, add it by using the tagDatabase Change Type as follows:

<changeSet id="13.1" author="liquibase">
<tagDatabase tag="version_2.0"/>
</changeSet>

Uses

The changelogSyncToTag goal is typically used when you want to baseline a new database environment with specific objects. An example use case for the changelogSyncToTag goal is the following:

  1. You have a DEV environment with a set of objects used only in DEV, and you want to use the same changelog to manage a new TEST environment. The TEST environment does not have those DEV-only objects and needs only some of them.
  2. To deploy the needed DEV-only objects and avoid deploying the rest, you add a tag and run the changelogSyncToTag goal to mark the changes related to that tag as executed in the DATABASECHANGELOG table.
  3. The goal marks all changesets starting with the first changeset at the top of the DEV changelog file and moving down to the changesets up to and including the tag.
  4. Next, you deploy the changesets that were not marked as deployed in your database. Liquibase treats your DEV and TEST databases as equivalent.

Note: If you want to mark all undeployed changes from the changelog file as executed in your database, use the Maven changelogSync

You can also use the changelogSyncToTag goal to mark the change associated with a specific tag as executed if the object associated with the change was created manually on the database. By marking the changeset as executed, it prevents the next Liquibase update from failing as it tries to create an object that already exists.

Maven configuration

Liquibase Maven can be configured in multiple ways. One way is to define your Liquibase configuration properties in your pom.xml file. To configure your pom.xml file, refer to Configuring Liquibase Attributes in your Maven POM File. If your pom.xml does not reference a liquibase.properties file, include <changeLogFile> specify your changelog file here</changeLogFile> to the pom.xml.

Running the changelogSyncToTag Maven goal

Running the changelogSyncToTag goal requires a Maven project to be implemented.

To run the goal, type the following in your command prompt:

mvn liquibase:changelogSyncToTag -Dliquibase.toTag=version_2.0

Note: Enter the name of the tag that you want to use in place of version_2.0.

Alternatively, you can add the goal and its attributes to the <executions> section of your pom.xml:

<executions>
<execution>
<phase>process-resources</phase>
<goals>
<goal>changelogSyncToTag</goal>
</goals>
<configuration>
<toTag>version_2.0</toTag>
</configuration>
</execution>
</executions>
