In the same page you can see this sentence:

If you have choosen to use MySQL or Postgresql in development, you can use the mvn liquibase:diff goal to automatically generate a changelog.

Liquibase Hibernate is a Maven plugin that is configured in your pom.xml, and is independant from your Spring application.yml file, so if you have changed the default settings (for example, changed the database password), you need to modify both files.

Here is the development workflow:

Modify your JPA entity (add a field, a relationship, etc.) Compile your application (this works on the compiled Java code, so don't forget to compile!) Run mvn liquibase:diff (or mvn compile liquibase:diff to compile before) A new "change log" is created in your src/main/resources/config/liquibase/changelog directory Review this change log and add it to your src/main/resources/config/liquibase/master.xml file, so it is applied the next time you run your application If you use Gradle instead of Maven, you can use the same workflow by running ./gradlew liquibaseDiffChangelog, and change the database configuration in liquibase.gradle if required.

So you just need change your JPA entities (remove, add, etc), run mvn compile liquibase:diff, and put the changes in master.xml.
