Jhipster jdl錯誤-“有效的源實體和目標實體是必需的”

Question

我試圖將我的jdl文件導入到我的jhipster項目中，但出現以下錯誤：

$ jhipster import-jdl ./Assets/jhipster-jdl.jh --serverOnly
Using JHipster version installed globally
Executing jhipster:import-jdl ./Assets/jhipster-jdl.jh
Options: serverOnly: true, server-only: true
The JDL is being parsed.

就是說我沒有要導入的有效jdl文件。 看着我的jdl，我找不到任何語法錯誤，並且錯誤消息沒有給我一行。 有任何想法嗎？

關系中的實體之一無效時，將返回此錯誤消息。 檢查JDL的relationship部分，確保關系兩側的實體存在並且拼寫正確。
