I’m trying to use use diffDatabaseToChangeLog from ant and I get this error:
C:\Production\jboss_emr\LiquiBase\build.xml:64: java.lang.ClassFormatError: Illegal class name “javax.persistence/src/javax/persistence/PersistenceException” in class file javax/persistence/PersistenceException
Here’s my ant target:
<diffDatabaseToChangeLog
driver=“oracle.jdbc.OracleDriver}”
url="${database.url}"
username="${database.username}"
password="${database.password}"
referenceUrl=“hibernate:ejb3:emrEJB”
outputFile="${hibernate.output.file}"
classpathref=“liquibase.classpath”
/>
liquibase.classpath contains these jars:
hibernate-commons-annotations-4.0.1.Final.jar
lib/hibernate-core-4.1.4.Final.jar
hibernate-entitymanager-4.1.4.Final.jar
hibernate-envers-4.1.4.Final.jar
liquibase-hibernate4.2-3.3.jar
liquibase.jar
ojdbc6.jar
persistence-api-sources-2.0.jar
snakeyaml-1.13.jar
If I removed persistence-api-sources-2.0.jar I get a ClassNotFoundException for PersistenceException.
I was running inside Eclipse, so to take that out of the picture I ran ant from the command line. Ant version is 1.8.0. Now I get this:
$ ant generateChangeLogFromEntities
Buildfile: C:\Production\jboss_emr\LiquiBase\build.xml
generateChangeLogFromEntities:

I had added all the jboss jars to classpathref for the diffDatabaseToChangeLog command, so it definitely includes the jar that has javax.persistence.spi.ClassTransformer.
Perhaps you could post an example build.xml that works using the EJB3 url. In addition I’m unclear how the hibernate integration finds the annotations in the entities. Should the classpathref include the compiled java classes or does it need the sources?
Thanks
ClassFormatError is a strange error to get. Are you running against a too-old version of Java?
