Feature Description

Following this guide on using go submodules I was able to recreate the functionality on GitHub, but when I moved to my private Gitea instance I was greeted with this error:

go: finding module for package git.example.com/Codebreaker101/testgo/b
go: downloading git.example.com/Codebreaker101/testgo v0.0.0-20220412181549-3b716bc4b575
git.example.com/Codebreaker101/testgo/a imports
        git.example.com/Codebreaker101/testgo/b: module git.example.com/Codebreaker101/testgo@latest found (v0.0.0-20220412181549-3b716bc4b575), but does not contain package git.example.com/Codebreaker101/testgo/b

You can use this script to test (just replace git.example.com/Codebreaker101/testgo with your own repo)

# init repo
go mod init git.example.com/Codebreaker101/testgo
git add go.mod
git commit -q -am 'Initial commit'
git push -q

# create b submodule
mkdir b
cd b
cat <<EOD >b.go
package b

const Name = "Gopher"
EOD
go mod init git.example.com/Codebreaker101/testgo/b
go test

# commit and tag b submodule
cd ..
git add b
git commit -q -am 'Add package b'
git push -q
git tag b/v0.1.1
git push -q origin b/v0.1.1


# create example
mkdir a
cd a
cat <<EOD >a.go
package main

import (
	"git.example.com/Codebreaker101/testgo/b"
	"fmt"
)

const Name = b.Name

func main() {
	fmt.Println(Name)
}
EOD
go mod init git.example.com/Codebreaker101/testgo/a
go mod tidy

Didn't test your script yet, but we're using go submodules on our instance and this works just fine.

I don't know then what am I doing wrong.

I was running an older version of Gitea (1.14.1)

Using the latest version fixes the problem.
