Maven update

update deploys any changes that are in the changelog file and that have not been deployed to your database yet.

Uses

update is typically used to apply database changes that are specified in the changelog file to your database.

When you run the update goal, Liquibase sequentially reads changesets in the changelog file, then it compares the unique identifiers of id, author, and path to filename to the values stored in the DATABASECHANGELOG table.

  • If the unique identifiers do not exist, Liquibase will apply the changeset to the database.
  • If the unique identifiers exist, the MD5Sum of the changeset is compared to the one in the database.
  • If they are different, Liquibase will produce an error message that someone has changed it unexpectedly. However, if the status of the runOnChange or runAlways changeset attribute is set to TRUE, Liquibase will re-apply the changeset.

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 pom.xml does not reference a Liquibase file, include <changelog-file>specify the changelog file here</changelog-file> to pom.xml.

Running the update Maven goal

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

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

mvn liquibase:update

When successful, the update Maven goal produces the following output:
