Build fails on Windows

[toedter]

Since I wanted to find the Windows-related issues, I tried to build the project on Windows, but it failed:

Here is the log:

Welcome to Gradle 6.8.2!

Here are the highlights of this release:

• Faster Kotlin DSL script compilation
• Vendor selection for Java toolchains
• Convenient execution of tasks in composite builds
• Consistent dependency resolution

For more details see https://docs.gradle.org/6.8.2/release-notes.html

Starting a Gradle Daemon (subsequent builds will be faster)

I'm having the same issue here.

This seems to come from the default windows git configuration when core.autocrlf=true. Line feeds are converted to CRLF when cloning the repo, and then the command prettier --check . fails because of this.

I could continue the build by launching manually the npm run format = prettier --write . which "fixes" the files with the intended line endings.

One suggestion i could make to make it work without changing user configuration would be, based on prettier documentation (emphasis by me)

If you want to make sure that your entire git repository only contains Linux-style line endings in files covered by Prettier:
- [...]
- Add * text=auto eol=lf to the repo’s .gitattributes file. You may need to ask Windows users to re-clone your repo after this change to ensure git has not converted LF to CRLF on checkout.

https://prettier.io/docs/en/options.html#end-of-line

NOTE: even the build continues, the tests also fails (some for the same line-ending mismatch reason)
