Question

更新：我已经更改了初始帖子的内容。我试图简化原来的问题，并且还提供了一些其他信息

我一直在尝试在旧版MS SQL Server数据库上使用db-reverse-engineer。在尝试使用实际系统之前，我通过了db-reverse-engineer教程，熟悉了基于生产的数据库可能需要的工具和模式。

在我们的项目上运行db-reverse-engineer之后，我将实体代码复制到使用 GORM独立的Groovy脚本（引用此Gist获取完整代码：https://gist.github.com/restagner/f2f740d5599efa202b08）

当我尝试运行脚本时，会产生以下错误并创建一个标有master_licenses的全新表格。我不知道如何解决这个问题。

我的印象是我可以使用addTo *样式方法添加某些域对象。我确信我忽略了一些明显的东西，但我无法弄明白。我已经查看了Grails文档，但无法了解我出错的地方。

并且，这里是每个表格的DDL列表
