Why does liquibase not start when the spring boot application starts? - spring-boot

Question

I am trying to create a basic database structure when starting a spring boot application. I need that when starting the task :bootRun was run by liquibase.
It starts without errors, a connection to the database is created, but liquibase does not start. It does not give errors, there is no information in the log about it.
Why doesn't it start automatically with spring boot?

I believe the spring property for the changelog file should not have the classpath reference:
spring.liquibase.change-log=db/...
instead of
spring.liquibase.change-log=classpath:db/...

I had a similar problem. This solved it for me https://stackoverflow.com/a/41960712/3999476
I have a multi module maven project, I had to move the dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
to the same module where I added the dependency for liquibase.

Just noticed that you've put the liquibase yaml in:
src/db/changelog/db.changelog-root.yaml.
Since the specified value is:
spring.liquibase.change-log=classpath:db/changelog/db.changelog-root.yaml
Could you put the file into:
src/main/resources/db/changelog/db.changelog-root.yaml?
