提示是jdl文件格式错误，但是在jdl-studio编辑文件没有任何错误提示
只好对jdl文件中的实体逐一排查:
最终问题是：实体 ｝ 后面的空格引发的血案，删除空格，再次导入，一切正常
温馨提示：
如果您在团队中工作，也许您希望拥有多个文件而不是一个文件。 我们添加了此选项，因此您不必手动将所有文件合并在一起， 而只需运行即可。
jhipster import-jdl my_file1.jdl my_file2.jdl
如果不想在导入JDL时重新生成实体，则可以使用--json-only标志跳过实体创建部分，仅在.jhipster文件夹中创建json文件。
jhipster import-jdl ./my-jdl-file.jdl --json-only
默认情况下，import-jdl仅重新生成已更改的实体，如果要重新生成所有实体，则传递--force 标志。 请注意，这将覆盖您对实体文件的所有本地更改
jhipster import-jdl ./my-jdl-file.jdl --force
如果要在项目中使用它，可以通过执行以下操作来添加它：
- NPM:
npm install jhipster-core --save
- Yarn:
yarn add jhipster-core
将其安装在本地，并将其保存在package.json文件中。
