Description

When we generate locally, on our macs, our TS SDK, the FILES file contains .openapi-generator-ignore in its list of files, while when we do the same thing in CI, on a Linux machine, the same file doesn't contain .openapi-generator-ignore in its list of files

openapi-generator version

7.10.0 (not yet released)

OpenAPI declaration file content or url

private. Can't share

Generation Details

java -jar openapi-generator-cli.jar generate \
  -i http://localhost:34567/docs/openapi/mydoc.json \
  -o "$1" \
  -g typescript-fetch \
  --additional-properties=disallowAdditionalPropertiesIfNotPresent=false,withInterfaces=false,supportsES6=true,stringEnums=true,npmName=myclient

Start with the typescript-fetch generator invoked by the provided openapi-generator-cli command and compare the generated FILES output on macOS and Linux. Reproduce with a shareable OpenAPI declaration or minimal fixture, then verify that both platforms produce the same FILES contents, including handling of .openapi-generator-ignore.
