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
orrunAlways
changeset attribute is set toTRUE
, 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 your pom.xml
does not reference a liquibase.properties
file, include <changeLogFile>specify your changelog file here</changeLogFile>
to the 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:
