This is what worked for running this app with Maven. I had to provide the -Dliquibase.changeLogFile path to mvn command:
mvn liquibase:rollback -Dliquibase.changeLogFile=/c/Projects/github/amitthk/myapp-db-updates/src/main/resources/db/changelog/db.changelog-master.yaml -Dliquibase.rollbackCount=1 -Dliquibase.rollbackId=8
