Java HSQLDB和Liquibase，表已存在：DATABASECHANGELOGLOCK

我试图用liquibase和HSQLDB实现单元测试。 一切正常。但由于某些原因，当liquibase尝试在数据库上应用更改日志时，我得到：

我无法理解为什么会发生这种事

上下文只引发一次。我看不到以前有人创建过这个表

HSQLDB也在内存中运行。所以有一个新的例子

有什么想法吗？ 以下是我的上下文和maven插件配置：

启动hsqldb
预集成测试
开始
停止hsqldb
整合后测试
停止

您正在运行哪个版本的liquibase？谢谢。我认为答案与您需要调用ChangeLogHistoryServiceFactory.getInstance（）.reset（）的答案相同在你清理数据库的地方，我最终会检查出来，移动到嵌入式mysql实例进行集成测试。但我更喜欢较轻的版本。你在同一数据库上使用不同的变更日志文件（例如，不同文件夹中的副本）吗？
