I am trying to reverse engineer a SQL Server 2005 using Hibernate Tools and am getting a strange error:
我正在尝试使用Hibernate Tools对SQL Server 2005进行逆向工程，并且出现了一个奇怪的错误：
org.hibernate.cfg.JDBCBinderException:
Duplicate class name 'CheckConstraints' generated for
'org.hibernate.mapping.Table(e2rm_maintenance_development2.sys.check_constraints)'.
Same name where generated for
'org.hibernate.mapping.Table(e2rm_maintenance_development2.sys.check_constraints)'
Duplicate class name 'CheckConstraints' generated for
'org.hibernate.mapping.Table(e2rm_maintenance_development2.sys.check_constraints)'.
Same name where generated for

A development user has typically access to multiple database schema s with similar tables. The Generation tool tries to generate output for all those databases and this results in duplicate class names (even if you ask for ddl generation).
开发用户通常可以访问具有类似表的多个数据库模式。生成工具尝试为所有这些数据库生成输出，这会导致重复的类名称（即使您要求生成ddl）。
Add a 'reveng' setup and limit the output to one database schema.
添加'reveng'设置并将输出限制为一个数据库模式。
Also add necessary parameters from the selected 'Exporters'. Some are necessary, but this is not indicated in the overview.
还可以从选定的“导出器”中添加必要的参数。有些是必要的，但概述中未说明。

I was able to avoid the error by creating "hibernate.reveng.xml" in which I excluded "sys" and "INFORMATION" schemas and only included "dbo" schema.

as a continue to Daniil Shevelev answer (this is what worked for me ) in order to exlude schema add new reveng.xml then choose new and on the next screen click next -then click refresh on the buttom (takes some time to get the schemas) then stand on the relevant scheme and exclude it 
作为继续Daniil Shevelev的回答（这对我有用）为了排除架构添加新的reveng.xml然后选择新的并在下一个屏幕上单击下一步 - 然后单击刷新按钮（需要一些时间来获取模式然后站在相关计划上并将其排除在外
