Generating code by jdl cannot adjust the original line separators, always convert code with LF instead of CRLF

[flyliu33]

Overview of the issue

I developed a project by jhipster with jdl on Windows 11 platform, after generating code by jdl, the line separator mode of the files of my project will tranform from CRLF to LF which conflict against git while comparing code by Jetbrains IDEAJ.

Motivation for or Use Case

Reproduce the error

1. Generate app from JDL (files are generated with LF ending)
2. Change the line separators of the whole project from LF to CRLF in IDEAJ. Select the root folder -> click File Menu -> select File Properties -> Select Line Separators -> Select CRLF.
3. Now all of the files would be CRLF mode.
4. Rerun app generation
5. Compare files in Commit View. It will show difference of line separators.

You should use --auto-crlf option.

[flyliu33]

This --auto-crlf option can work, I suggest if there are some descriptions for these kind of options on Jhipster Docs could be easy for developers.
Additionally, since my project is based on microservices architecture, while I executed command jhipster jdl .\store\microservice-ecommerce-store-4-apps.jdl --auto-crlf, error arose at the end, but the result is still successful. I am not sure if it need a optimization, because my ms-ecommerce-store as a regular root directory is actual without git management. And gateway and each microservice have their owe git configuration.
