Maven changelogSync
changelogSync updates the DATABASECHANGELOG table to mark all changes that are not applied to the database as executed.
Uses
changelogSync is typically used when you want to baseline a new database environment.
An example use case for the changelogSync goal is when 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 or need those DEV only objects. To avoid deploying the DEV only objects, you can run the changelogSync goal to mark those changes as executed in the DATABASECHANGELOG which tells Liquibase to treat these databases as equivalent.
You can also use the changelogSync goal to mark a change 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
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
Tip: For more information about the Maven configuration, see Configuring Maven.
Running the changelogSync Maven goal
Running the changelogSync goal requires a Maven project to be implemented.
To run the goal, type the following in your command prompt:
mvn liquibase:changelogSync
Output
When successful, the changelogSync Maven goal produces the following output:
