NullPointerException executing a diff-database in 2.0RC1

General Discussion
1

Liquibase gives a NullPointerException at liquibase.database.typeconversion.core.AbstractTypeConverter.getDataType (AbstractTypeConverter.java:55). I try to execute a diffDatabase where there are changes in datatypes from columns in the db (and new tables and relations).
The 2.0RC1 generateChangeLog ant task works perfectly with the same hibernate files, generating all datatypes.
The 1.9.4 diffDatabaseToChangeLog ant task works “perfectly” with the same hibernate files, generating changes without taking into account of datatype changes.

I’ll take a look.  Thanks!

The error is that the liquibase.jar included in liquibase-2.0-rc1-bin.zip from the direct link of download page is out of date.
The class liquibase.diff.DiffResult was updated at 28/10/09 in SVN when the .jar is from 8/10/09.
I think the error was solved including a not null condition statement.

Can someone compile a snapshot of the project?

You can get the current build from our buildserver: http://liquibase.org/ci/latest

Could you try that out? 

Thanks,
Nathan

It works with the last library snapshot (liquibase-2.0-rc2.jar 11/17).

Thanks,
