liquibase不生成表DATABASECHANGELOG

Question

我是liquibase的新手，我想在生产中的数据库上使用它。这是一个很小的应用程序，但我不想手工创建模式，而是想使用更专业的东西，比如LiquiBase。

我计划做的是在生产中的当前模式和新模式之间为新应用程序准备一个changelog。我已经遵循了许多教程，但仍然缺少一些东西。输出changelog.xml总是导入所有模式，并且与现有模式没有区别。我看到liquibase必须创建表DATABASECHANGELOG，但我在计算机上看不到它们。

我所做的：

• 生产中当前数据库的转储和在开发计算机上的导入
• 从core project添加了liquiBase.properties并启动了以下命令：mvn clean resources：resources liquiBase:generateChangelog
• 这生成了一个包含所有模式的master.xml，但没有在DB中创建表databaseChangeloglog（表DATABASECHANGELOGLOCK是在注释outputChangeLogFile时创建的，锁定的值为0)
• 从http://www.liquibase.org/databases.html手动创建DATABASECHANGELOG
• 重新运行命令mvn liquibase：generateChangelog。仍然一无所获

据我所知（我也是新手），表DATABASECHAGELOG和DATABASECHANGELOGLOCK是由update选项创建的：mvn liquibase：update
