Getting error during liquibase:diff

General Discussion
1

I am using liquibase hibernate maven plugins. The entity class are annotation driven. When I do liquibase:diff I get the below warning but the changelog seems to get generated successfully.

Is this just a warning that can be ignored ? if Yes then how to supress this warning from appearing
If No how to fix this issue.
