我正在尝试在现有的derby数据库上运行generateChangeLog。它有很多表格。
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`
结果输出表示成功：
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
INFO 13/03/15 14:27: liquibase: Can not use class liquibase.serializer.core

Liquibase 'generateChangelog' Successful
调试跟踪是：

但创建的xml文件基本上是空的
有人可以提出任何建议来帮助我吗？
