【问题描述】：

我有一个由 JHipster 6.7.0 生成的 Monolith 应用程序。我的 JHipster 本地版本是 7.0.1。当我尝试使用 jhipster import-jdl app.jdl 命令导入新实体时，我遇到了与已经可用的实体有关的问题。

ERROR! Error at entity Ticket: relationship name is not synchronized 
   "relationshipName": "jobs",
   "otherEntityName": "ticketJob",
   "relationshipType": "one-to-many",
   "otherEntityRelationshipName": "ticket",
   "otherEntity": "[TicketJob Entity]",
   "otherEntityField": "id",
   "ownerSide": false,
   "collection": true,
   "otherSideReferenceExists": false,
   "otherEntityIsEmbedded": false

   "relationshipName": "ticket",
   "otherEntityName": "ticket",

   "otherEntityRelationshipName": "ticketJob",
   "otherEntity": "[Ticket Entity]",
   "ownerSide": true,
   "collection": false,

       "dynamic": false,

       "fieldNameCapitalized": "Id",

       "fieldWithContentType": false,

       "columnName": "id",
       "fieldInJavaBeanMethod": "Id",
       "fieldValidate": false,
       "nullable": true,
       "unique": false,
       "uniqueValue": [],
       "path": [
           "id"
       ],
       "relationshipsPath": [],
       "reference": "[id Reference]",
       "relatedByOtherEntity": true
    

是否可以在导入新版本的新实体时跳过现有实体？还是更容易将现有实体升级到最新版本？ （即使我尝试使用 jhipster upgrade 命令升级应用程序，我也会遇到同样的问题

【参考方案1】：

问题在于.Jhipster 目录中的 JSON 文件。每当我们升级 JHipster 或导入新实体时，JHipster 都会使用 .JHipster 目录中的 JSON 文件运行整个实体。

我无法获得确切的解决方案，但我确实设法找到了解决方案。我刚刚创建了一个正在创建问题的新实体。我导入了为实体生成新 JSON 文件的实体。我忽略了在导入这个新的 JDL 文件时创建的其他文件。之后，我就可以升级 JHipster 项目了。
