I want to create Liquibase _changelog file_ based on differences between my database and my Hibernate entities for different database environments, therefore different datatypes in Oracle, SQL Server and PostgreSQL. And it’s a Maven Project. So, is there any Maven plugin or can be generated to do this operations?

Also I tried liquibase-hibernate plugin, but it is not working properly, sometimes diff cannot see any difference although I made changes in `Entity.java`.

So this is what I wanted as a workflow in dev;

1. Make a change in my `Entity.java`
2. Run a command like `mvn:migrateAll` including liquibase diff
3. Changelog file for all databases are generated based on difference
4. Run `mvn:liquibase update` command to update my tables.
