问题
我使用描述我的数据库对象结构的 YAML 脚本。这非常方便，因为我可以使用 H2 进行基于 DB 的集成测试。
但是我的客户的生产服务要求我们提供面向 Oracle 的 SQL 脚本（他们使用 Liquibase，但以非标准方式，我们无法挑战/更改）。
因此，我想以自动方式从我的 YAML 脚本生成这些 Oracle SQL 脚本。
想法
我首先找到了Liquibase:updateSQL 命令。问题是我无权访问数据库（我不知道 JDBC URL，我也不在同一个网络上）。所以这个解决方案是行不通的。
然后，我在 Liquibase 中发现了一个新选项，它允许updateSQL 命令的“离线”模式。这似乎确实是我正在寻找的解决方案，但随后出现以下错误（使用 Maven 和 -X -e 选项）：

然后我重新尝试离线 H2 基地，但我有一个新的错误：

所以我的问题是：
- Liquibase:updateSQL 在您看来是正确的解决方案吗？
- 您是否成功在 Oracle 的离线模式下执行 Liquibase:updateSQL 命令？（如何 ？）
