Cannot compile client using Go modules

[nnathan]

I'm trying to write a program using the clientv3 client.

package main

import (
	"fmt"
	"time"

	"github.com/coreos/etcd/clientv3"
)

func main() {
	baseconfig := clientv3.Config{
		Endpoints:            []string{"http://127.0.0.1:2379"},
		DialTimeout:          2 * time.Second,
		DialKeepAliveTime:    2 * time.Second,
		DialKeepAliveTimeout: 6 * time.Second,
	}

	client, err := clientv3.New(baseconfig)

	if err != nil {
		fmt.Printf("error creating client: %v", err)
	}

	_ = client
}

I'm also using Go modules. When I try to build the example program:

Maybe I shouldn't be building off the latest tree, but I don't know how to dial back to a stable version of etcd using go modules either. Any help would be appreciated.

[santoshkowshikhr]

I am having the same issue as well, tried manually cloning 3.4 version ran into same error.

[tennessine]

Is this project dead?
It's so hard to use, even write a simple hello world example.
Why?

[nnathan]

@tennessine It seems to be impossible to contact with anyone that works on etcd.

google.golang.org/grpc v1.26.0

[cfc4n]

@gyuho go mod will get lastest version package default. GRPC-GO's lastest version was 1.29.1 at https://pkg.go.dev/google.golang.org/grpc?tab=doc . Do you have some ideas about this bug?
add a go.mod file to git repository?

ref. #11931

/cc @gyuho @mitake @spzala

[cfc4n]

@nnathan or use this shell

$ go mod edit -replace=google.golang.org/grpc=google.golang.org/grpc@v1.23.0
$ make
