General Discussion
1

hi, I’m trying to obtain hibernate changes by:

       

it works with 1.9.5 if “referenceUrl” is replaced with “baseUrl”

but for 2.0 RCs i’ve got:
DatabaseException: driver not specified and no default could be found for hibernate:hibernate-development.cfg.xml

any ideas?

thanks

Did you add the hibernate extension jar as listed in http://liquibase.org/v2_upgrade ?  I pulled the hibernate support out so it can be developed more independently from the core liquibase library.

Missed this point… Thanks

Now I’ve got NPE in AbstractTypeConverter.getDataType(AbstractTypeConverter.java:60) in RC6

could not check on latest build: http://liquibase.org/ci/latest.html doesn’t seem to work for me. am i using wrong link?
RC5 works, but shows:

    [diffDatabaseToChangeLog] INFO 07/10/10 10:49:liquibase: Can not use class liquibase.executor.LoggingExecutor as a Liquibase service because it does not have a default constructor BUILD SUCCESSFUL

RC6:

    [diffDatabaseToChangeLog] seen table SystemVariable

The link is right.  The project that was hosting our CI server has apparently given up on getting their server fixed.  I’m in the process of trying to figure out other options.

I fixed the null pointer in trunk for the next build.
