Jhipster jdl错误-“有效的源实体和目标实体是必需的”

[英]Jhipster jdl error - `Valid source and destination entities are required`

I am trying to import my jdl file into my jhipster project but I am getting the following error: 我试图将我的jdl文件导入到我的jhipster项目中,但出现以下错误:

$ jhipster import-jdl ./Assets/jhipster-jdl.jh --serverOnly

It's saying that I don't have a valid jdl file to be imported. 就是说我没有要导入的有效jdl文件。 Looking at my jdl, I can't find any syntactical errors and the error message does not give me a line. 看着我的jdl,我找不到任何语法错误,并且错误消息没有给我一行。 Any ideas? 有任何想法吗?

This error message is returned when one of of the entities in relationships is invalid . 关系中的实体之一无效,将返回此错误消息。 Check the relationship sections of your JDL, make sure the entities on both sides of the relationship exist and are spelled correctly. 检查JDL的relationship部分,确保关系两侧的实体存在并且拼写正确。
