How Can I Use `go get` or `go dep` to Manage Dependencies from Private GitLab Subgroups?

Managing GitLab Subgroup Dependencies in Go with 'go get' or 'go dep'

When implementing Go projects that require dependencies from private GitLab repositories organized into subgroups, users can encounter errors that prevent successful retrieval of the necessary packages. This article delves into a common issue and provides a comprehensive solution using 'go get' and 'go dep'.

The erroneous message "remote repository at https://git.mydomain.com/myteam/category.git does not exist or is inaccessible" arises when attempting to acquire dependencies from a private GitLab repository. This issue, as detailed in the GitLab support tracker, is an intentional security measure for private repositories.

To overcome this limitation, one viable solution is to leverage 'go get's compatibility with the '.netrc' file format, which enables both 'dep' and modern Go modules to access private repositories.

Step-by-Step Solution:

1. Generate a Personal Access Token from GitLab with the 'api' scope.

2. Establish a '.netrc' file in your root directory:

   machine gitlab.com
   login <your gitlab username>
   password <the token from step 1>

3. Safeguard your '.netrc' file by restricting permissions:

   chmod 600 ~/.netrc

With the '.netrc' file configured, you can now seamlessly acquire dependencies using 'dep ensure':

   dep ensure -add gitlab.com/<company>/<subgroup>/<project>

Or 'go get':

   go get gitlab.com/<company>/<subgroup>/<project>

For private GitLab installations, substitute 'gitlab.com' with the appropriate hostname.

By adopting this solution, you can effectively handle dependencies in Go projects that utilize GitLab subgroups, ensuring uninterrupted development processes and seamless dependency management.
