java - 从 JDL 文件添加 jHipster 实体时出错

Question

我是新来的。我正在尝试使用 JHaspter 创建一个新的应用程序。

我使用了“yo jhipster”命令来生成应用程序。

我已经使用 JDL studio 来开发我的实体，但是，当我将 JDL 与“yo jhipster:import-jdl model.jdl”一起使用时，我收到错误 - 但错误消息没有提供任何关于什么是的线索导致错误。

我看到的错误消息和 JDL 文件的内容如下。请让我知道如何调试这个。请注意，我对 jhipster 和 StackOverflow 来说都是新手。

调整你的人际关系。我不确定您的数据是如何配置的，但类似于下面的内容。文档 https://jhipster.github.io/jdl/提供了更好的解释。

    relationship ManyToOne {
    Device{product} to Product{device},
    PurchaseOrder{user} to User{purchaseorder},
    Product{brand} to Brand{product},
    Offer{product} to Product{offer},
    Bundle{product} to Product{bundler},
    Offer{bundle} to Bundle{offer},
    Location{country} to Country{location}
}

不需要提供默认的“ID”列。希望对您有帮助
