# When you want to reference a private repository

## Overview

When building with Diarkis-cli, if the project references a private repository, an authentication error occurs on the build server. This document explains how to circumvent this issue.

## Problem

If you attempt to build as is, the build server of Diarkis-cli will encounter an authentication error with the code in your private repository.

## Solution

You can avoid this issue by following these steps:

1. **Copy the private repository code locally**

   Copy the directory of the private repository into the same repository.
2. **Modify go.mod**

   Change it to reference the local repository as shown below:

   ```go
   require (
   	github.com/Org/privateModule v0.0.0-00010101000000-000000000000
   )

   replace github.com/Org/privateModule => ./private-module // change Org and privateModule
   ```

   (Replace 'Org' and 'privateModule' with the actual names as needed)
3. **Execute the build**

   Proceed with the build as usual, and it should succeed.

## TIPS

By specifying unnecessary files from the local private repository directory in `.buildignore`, you can reduce the amount to be uploaded.
