What did you do?

I have a private repo: https://my.gitlab.com/group0/group1/group2/repo . And group0, group1 and group2 are all group names.

And then I want to use it as a dependency in another repo in go.mod file.

But go mod tidy -v thinks that the repo is my.gitlab.com/group0/group1

$ go mod tidy -v 
get "my.gitlab.com/group0/group1/group2/repo": found meta tag get.metaImport{Prefix:"my.gitlab.com/group0/group1", VCS:"git", RepoRoot:"https://my.gitlab.com/group0/group1.git"} at //my.gitlab.com/group0/group1/group2/repo?go-get=1

What did you expect to see?

I want the go mod works.

What did you see instead?

get "my.gitlab.com/group0/group1/group2/repo": found meta tag get.metaImport{Prefix:"my.gitlab.com/group0/group1", VCS:"git", RepoRoot:"https://my.gitlab.com/group0/group1.git"} at //my.gitlab.com/group0/group1/group2/repo?go-get=1
get "my.gitlab.com/group0/group1/group2/repo": verifying non-authoritative meta tag
go: my.gitlab.com/group0/group1/group2/repo@v0.0.3: reading my.gitlab.com/group0/group1/group2/repo/group2/repo/go.mod at revision group2/repo/v0.0.3: unknown revision group2/repo/v0.0.3

I add some logs in function repoRootForImportDynamic in file src/cmd/go/internal/get/vcs.go

func repoRootForImportDynamic(importPath string, mod ModuleMode, security web.SecurityMode) (*RepoRoot, error) {
	url, err := urlForImportPath(importPath)
	if err != nil {
		return nil, err
	}
	fmt.Printf("importPath: %s, url: %v, err: %v\n", importPath, url, err)
	resp, err := web.Get(security, url)
	if err != nil {
		msg := "https fetch: %v"
		if security == web.Insecure {
			msg = "http/" + msg
		}
		return nil, fmt.Errorf(msg, err)
	}
	body := resp.Body
	defer body.Close()
	bodyData, err := ioutil.ReadAll(body)
	imports, err := parseMetaGoImports(bufio.NewReader(bytes.NewBuffer(bodyData)), mod)
	fmt.Printf("imports: %v, err: %v, \nbody: %s, \nmod: %v\n", imports, err, bodyData, mod)
...
	// Find the matched meta import.
	mmi, err := matchGoImport(imports, importPath)
	fmt.Printf("imports: %v, importPath: %v, mmi: %v, err: %v\n", imports, importPath, mmi, err)

...
}

logs are

importPath: my.gitlab.com/group0/group1/group2/repo, url: //my.gitlab.com/group0/group1/group2/repo?go-get=1, err: <nil>
imports: [{my.gitlab.com/group0/group1 git https://my.gitlab.com/group0/group1.git}], err: <nil>, 
body: <html><head><meta name="go-import" content="my.gitlab.com/group0/group1 git https://my.gitlab.com/group0/group1.git" /></head></html>, 
mod: 1
imports: [{my.gitlab.com/group0/group1 git https://my.gitlab.com/group0/group1.git}], importPath: my.gitlab.com/group0/group1/group2/repo, mmi: {my.gitlab.com/group0/group1 git https://my.gitlab.com/group0/group1.git}, err: <nil>

It looks like your server returned the wrong go-import meta tags for this path — this does not seem to be a bug in cmd/go. You'll need to open a ticket with whoever maintains your server (or perhaps with GitLab).

See https://golang.org/ref/mod#vcs-find for documentation on the go-import protocol.
