cd swag-bug-example/main
swag init -g ./main.go -o .

Expected behavior
no errors should occur.

Your swag version
v1.16.3

Your go version
go1.22.

swag init --parseDependency -g ./main.go -o .

You need to add option --parseDependency.

I have the same problem - but it gives me an error saying the external package is missing when it's in both the go.mod and go.sum

running swag init --parseDependency produces:

missing go.sum entry for module providing package github.com/hcpd-solutions/pki; to add:
	go mod download github.com/hcpd-solutions/pki
missing go.sum entry for module providing package github.com/hcpd-solutions/pki; to add:
	go mod download github.com/hcpd-solutions/pki
