添加jHipster實體形成JDL文件時出錯

Question

我是新來的。我正在嘗試使用JHispter創建一個新的應用程序。

我已經使用「yo jhipster」命令來生成應用程序。

我已經使用JDL工作室來開發我的實體，但是，當我使用帶有「yo jhipster：import-jdl model.jdl」的JDL時，我收到一個錯誤 - 但錯誤信息並不能提供什麼線索導致錯誤。

我看到的錯誤信息和我的JDL文件的內容如下。請讓我知道我該如何調試。請注意，我是一個完全新手jysster，以及StackOverflow。

調整你關係。我不確定您的數據是如何配置的，但是與以下內容類似。文檔https://jhipster.github.io/jdl/提供了更好的解釋。

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} 
} 

沒有必要提供默認的「ID」列。希望它有幫助
