Golang example to consume Confluent Kafka does not contain the go.mod and the build does not work

[rogerioefonseca]

Description
I tried to go through the step by step mentioned in the documentation:
https://docs.confluent.io/platform/current/tutorials/examples/clients/docs/go.html?ajs_aid=7077fcce-0d54-4277-a0c0-50c875f49cd2&ajs_uid=718849

While trying to execute it the error message was triggered:

I realized that there is no go.mod in the project, and the import of "./ccloud" is breaking. (Honestly could be an ignorance on my side, I do not know how to use those relative imports)
Then I needed to first create a module with go mod init anything/r and go mod tidy

Troubleshooting
Change That I needed to do in the code to make it work

//Change That I needed to do in the code
import (
	"anything/r/ccloud"
	"encoding/json"
	"fmt"
	"gopkg.in/confluentinc/confluent-kafka-go.v1/kafka"
	"os"
	"os/signal"
	"syscall"
	"time"
)

Then after that, I was able to use the example successfully
./producer -f $HOME/.confluent/librdkafka.config -t test1
