  4. 0 I am having a small issue with the hibernate integration. I noticed that you split the hibernate aspect of liquibase into separate extension jar file in v2. I guess the documentation is a little out of date. Anyway having downloaded that, I now get a little further. The output I now get is D:\apps\liquibase-2.0.1-bin>java -jar liquibase.jar --logLevel=debug diff DEBUG 14/02/11 12:46:liquibase: Unable to load/access Apache Derby driver class to check version: DEBUG 14/02/11 12:46:liquibase: Connected to XTS_CHRIS@jdbc:oracle:thin:@asus4:1 521:XE WARNING 14/02/11 12:46:liquibase: Unknown database: Hibernate DEBUG 14/02/11 12:46:liquibase: Reading tables for unsupported Database ...

My take on the getMetaData method is that it will always return null, hence fail for a hibernate driver. So it appears to me that something must have changed in this area, or I am doing something wrong.
