What do I need to do to execute sample golang code having a 'named' import like below? - go

Question

This is newbie question. The dependencies seems to be on github, and it's pretty obvious from the import, so why run doesn't work?
Error is: no required module provides package github.com/hashicorp/go-getter
package main
import (
"context"
"fmt"
"os"
// Problem with line below, getting error: no required module provides package
getter "github.com/hashicorp/go-getter"
)
func main() {
client := &getter.Client{
Ctx: context.Background(),
//define the destination to where the directory will be stored. This will create the directory if it doesnt exist
Dst: "/tmp/gogetter",
Dir: true,
//the repository with a subdirectory I would like to clone only
Src: "github.com/hashicorp/terraform/examples/cross-provider",
Mode: getter.ClientModeDir,
//define the type of detectors go getter should use, in this case only github is needed
Detectors: []getter.Detector{
&getter.GitHubDetector{},
},
//provide the getter needed to download the files
Getters: map[string]getter.Getter{
"git": &getter.GitGetter{},
},
}
//download the files
if err := client.Get(); err != nil {
fmt.Fprintf(os.Stderr, "Error getting path %s: %v", client.Src, err)
os.Exit(1)
}
//now you should check your temp directory for the files to see if they exist
}

Create a folder somewhere called getter, then create a file
getter/getter.go:
package main
import (
"fmt"
"github.com/hashicorp/go-getter/v2"
)
func main() {
fmt.Println(getter.ErrUnauthorized)
}
Notice I didn't use a name like you specified, as it's redundant in this case. The package is already called getter [1], so you don't need to specify the same name. Then, run:
go mod init getter
go mod tidy
go build
https://pkg.go.dev/github.com/hashicorp/go-getter/v2
