MongoDB 的 liquibase generateChangeLog 错误

Question

是否可以从现有的 MongoDB 数据库生成更改日志？

❯ liquibase generateChangeLog

Liquibase 属性：

changeLogFile: _changelog.xml

网址：mongodb://localhost:27017/test?authSource=admin

用户名：xxx

密码：xxx

日志级别：信息

有没有我遗漏的配置？

目前，不支持使用 liquibase-mongodb 扩展的 generatechangelog。我用这个issue 作为参考。

但是，您可以请求功能here。
