I’m trying to run generateChangeLog on an existing derby database. It has a number of tables in it.
c:\Projects\core\cams>java -jar lib\liquibase.jar --classpath=derby.jar;derbyclient.jar --driver=org.apache.derby.jdbc.EmbeddedDriver --url=“jdbc:derby:CAMSDB” --changeLogFile=db-changelog.xml --logLevel=debug --logFile=log.txt generateChangelog
The resulting output indicates success:
INFO 13/03/15 14:27: liquibase: Can not use class liquibase.serializer.core
.json.JsonChangeLogSerializer as a Liquibase service because org.yaml.snake
yaml.representer.Representer is not in the classpath

Liquibase ‘generateChangelog’ Successful
The debug trace is:

Why is it not working?
