Answer
My guess is that your Liquibase files are in a folder named liquibase. Rename it to something else like liquibase-migration-files or equivalent, but definitely different from just liquibase.
My interpretation is that having a liquibase folder make the ClassLoader think the package liquibase is declared in the module where your Liquibase configuration is stored, thus the ClassLoader doesn’t try to look in the unnamed module where the Liquibase library is located.
