Code example or link to a public repository

test.go:

package main

var unused int

func main() {
	print()
}

Only test.go file is present in the current directory:

$ ls -a .
.       ..      test.go

It's because the go.mod is missing

@ldez Thank you so much! I understand the behavior change. 👍

When I turn off GO111MODULE, I confirm golangci/golangci-lint:v1.37.1 works well.

$ docker run --env GO111MODULE=off --rm -v $(pwd):/app -w /app golangci/golangci-lint:v1.37.1 golangci-lint run
test.go:3:5: `unused` is unused (deadcode)
var unused int
    ^

I'll close this issue if no problems or concerns. Thanks!
