OData Vdm 生成器 returns 特定 EDMX 文件出错
OData Vdm Generator returns an error on a particular EDMX file
我正在尝试使用 EDMX 文件上的 odata-generator-cli-3.52.0 生成 类，您可以从以下 API 中心 link 下载该文件： https://api.sap.com/api/ProjectServiceV2/overview。我正在使用的命令如下：java -jar odata-generator-cli-3.52.0.jar -b "/"，但是，我收到了这个错误（当使用 generato 作为 Maven 插件时我得到了同样的错误）：

你知道这个文件的问题在哪里吗？

问题出在 EDMX 规范文件中。对于导航 属性 toUser 引用了未定义的实体类型，即 Users.
<NavigationProperty Name="toUser" Relationship="service.ProjectServiceV1.GroupMemberships_toUser" FromRole="GroupMemberships" ToRole="Users"/>
从 EDMX 文件中删除此 属性 及其关联的 Association 和 AssociationSet 会导致成功生成 VDM。
