java.lang.IncompatibleClassChangeError: Implementing class

I am using Liquibase to generate a changelog based upon modifications to the Hibernate mapping files.


  1.        
                 
                     
                 
           
           
               
           
            <diffDatabaseToChangeLog
                    driver="${database.driver}"
                    url="${database}"
                    referenceUrl=“hibernate:hibernate.cfg.xml”
                    username="${sql.user}"
                    password="${sql.pass}"
                    referenceUsername="${sql.user}"
                    referencePassword="${sql.pass}"
                    outputFile=“build\db-changelog.xml”
                    classpathref=“liquibase-classpath”>
           
       



but I get the following error:

Any suggestions?

Sorry, it was an incompatible hibernate-annotations jar.
