Description of the problem

Autogenerated files from swagger-codegen are not ignored by golangci-lint.

Really, this is something that should be fixed on the swagger-codegen side (and there is an open bug here), because it does not include the standard ^// Code generated .* DO NOT EDIT\.$ pattern.

The golangci-lint configuration docs say:

# There is no need to include all autogenerated files,
# we confidently recognize autogenerated files.
# If it's not, please let us know.

So I thought I'd report it anyway.

I also tried setting exclude-generated: lax, but this does not exclude these files either.

You could add an ignore pattern for Generated by: Swagger Codegen to catch these files.

A minimal reproducible example or link to a public repository

Generate swagger files using swagger-codegen (docker example for portability):

docker run --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli generate \
    -i https://petstore.swagger.io/v2/swagger.json \
    -l go \
    -o /local/out/go

Run golangci-lint against those files. It'll probably fail against things like revive for missing exported var comments, lll for being too long, etc.
