问题
This question is related to "Hibernate using JPA (annotated Entities) and liquibase".
I was actually wondering what to expect when doing a Liquibase diff against a Hibernate mapping definition.
What it seems to produce: A liquibase changelog that migrates the state of my hibernate mappings to the current image of the database.
What I was hoping for: A liquibase changelog that migrates the existing (old) database to reflect the changes in my (new) hibernate mappings.
Am I expecting the wrong thing? or am I doing something wrong?
Thank you for letting me know! J.

The answer was too obvious...
It was just a matter of flipping the base- and target system :-)
--username=un \
--password=pw \
--url=jdbc:mysql:///mydb \
diffChangeLog \
--baseUrl="hibernate:/hibernate.hbm.xml"
becomes:
--url="hibernate:/hibernate.hbm.xml" \
diffChangeLog \
--baseUrl=jdbc:mysql:///mydb \
--baseUsername=un \
--basePassword=pw
Sorry! Time for sleep :-)
