我正在使用liquibase 3.3.2,Hibernate 4.3.0.Final,java 1.7.0_71和liquibase-hibernate4-3.5.jar.我的CLASSPATH环境变量是空的,但liquibase shell脚本会添加一些东西.当我使用正常的liquibase命令进行交互时,我从$LIQUIBASE_HOME / lib /目录中删除了没有扩展名的扩展名,它可以正常工作.我用DEBUG输出重新启动命令以提供更多信息.

如果我取消注释我的referenceDriver,我会得到这个.这里有什么我想念的吗?我以为我拥有所有必需的依赖项,而且我不确定这是否是早期问题的一些表现,其中扩展无法正确加载内容.

将hibernate jar添加到liquibase / lib文件夹后(这确实是错误的),错误变成了这个.我尝试恢复到旧版本的插件(同时降级liquibase),但它没有帮助.

解决方法
我经历的过程是:
>下载这里找到的正确插件项目的源代码(https://github.com/liquibase/liquibase-hibernate/releases),在我的情况下,它是liquibase-hibernate4-3.5.
>运行mvn依赖:copy-dependencies.这会将它们转储到/ target / dependency /中.复制所有这些jar并将它们放入LIQUIBASE_HOME / lib目录中.
>我正在使用gradle,所以我使用自定义任务来复制所有依赖项.如果你正在使用maven,你可以使用自己项目中2的相同步骤来获取所有的depdenencies.我将这些库从输出目录复制到LIQUIBASE_HOME / lib目录中.
task copyToLib(type: Copy) { into "$buildDir/output/libs" from configurations.runtime }
>我还将正确的hibernate-liquibase-4.3.5.jar放入LIQUIBASE_HOME / lib目录中.
这给了我插件所需的所有依赖项.
这是一个令人讨厌的混乱球,但你能做什么:(
