Jhipster jdl 错误 - `需要有效的源和目标实体`

Question

我正在尝试将我的 jdl 文件导入我的 jhipster 项目，但出现以下错误：

$ 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.
Error: Valid source and destination entities are required.

这是说我没有要导入的有效 jdl 文件。查看我的 jdl，我找不到任何语法错误，并且错误消息没有给我一行。有什么想法吗？

Answer 1

one of of the entities in relationships is invalid 时返回此错误消息。检查 JDL 的 relationship 部分，确保关系两边的实体存在且拼写正确。
