skipIfSpecIsUnchanged: true not working across operation systems

[huchenhai]

Description

hi we are experiencing issue, the "skipIfSpecIsUnchanged: true" is not working for developers who are using windows system. The codegen always regenerates source code even there is no change under openapi.yml.
However the config is working fine for MacOS developers.

Swagger-codegen version

Command line used for generation

mvn verify install

Suspecting if the is difference on file encoding and end of line sequence between windows and mac. and also some effect on the sha256 files under .openapi-generators folder?
