Sample to import a private repository

[filip7sr]

Hi!

I'm currently trying to migrate some of our GitHub repositories to Azure Devops. While importing public repositories isn't an issue, I can't manage to create an ImportRequest that uses a token.

My current code looks like this

GitRepository createdRepo = azureGitClient.CreateRepositoryAsync(new GitRepository
		{
			Name = repo.Name,
			ProjectReference = new TeamProjectReference
			{
				Id = archiveProject.Id
			}
		}).Result;

		azureGitClient.CreateImportRequestAsync(new GitImportRequest()
		{
			Repository = createdRepo,
			Parameters = new GitImportRequestParameters()
			{
				GitSource = new GitImportGitSource() { Url = repo.GitUrl }
			}
		}, archiveProject.Id, createdRepo.Id);

I can't imagine I'm the only one that wants to import several repositories, so I'm sure an example would come in handy! :)

Agreed. I'm doing some POC's and I'm unable to figure how to pass the credentials for the source repo. Importing public repos works fine.

I think, the solution is to create a ServiceEndPoint in the Azure DevOps project settings. Then, you need to find out the ID of this ServiceEndPoint by going to https://dev.azure.com/[yourOrganization]/[projectName]/_apis/distributedtask/serviceendpoints and get the ID.

I used the following code successfully to import the Git repository from a different Azure DevOps project:

var importRequest = new GitImportRequest
            {
                Repository = new GitRepository()
                {
                    Id = newRepoId, // the repository id of the existing, empty repository with size=0 to import into ...
                    Name = newRepoName, // the name of the existing, empty repository with size=0 to import into ...
                },
                Parameters = new GitImportRequestParameters()
                {
                    GitSource = new GitImportGitSource()
                    {
                        Url =  "https://[sourceOrg].visualstudio.com/[sourceProj]/_git/[sourceRepo]"
                    },
                    ServiceEndpointId = new Guid("[the guid of your service endpoint to sourceOrg]"),
                    DeleteServiceEndpointAfterImportIsDone = false,
                    TfvcSource = null
                }
            };

            var importedRepo = client.CreateImportRequestAsync(importRequest, projectName, newRepoName).Result;

Attention! PAT did not work for me, even when trying to import from a repository that is from a project of the SAME Azure DevOps organization! I was not able to get it working, when I was creating a service endpoint with PAT token, only with basic authentication! (Also, I only tested it, when I used basic authentication credentials generated by my own DevOps account so far)

Attention! I was not able to share the service endpoint / service connection with other projects! (the policy: 'Allow all pipelines to use this service connection' seems not to allow other projects to import via this service endpoint Guid)

Attention! There is also a property 'Overwrite' available for creating a new GitImportGitSource. In none of my tests, I got it working when using this property.

I was able to get this to work:

1. Make sure you create a repository in the destination project.
2. Create a service endpoint in the destination project using your alternate credentials for Azure DevOps.
3. Get the GUID from the URL provided by @achimismaili
4. Ensure you use the destination repository id in CreateImportRequestAsync(...)

Here is a snippet of my code:

var srcProjectName = "the name of the source project";
var destProjectName= "the name of the destination project";
var prefix = "the prefix for the repository names in the destination project, if any";

// Get a GitHttpClient to talk to the Git endpoints
var gitClient = connection.GetClient<GitHttpClient>();

var sourceRepos = await gitClient.GetRepositoriesAsync(project: srcProjectName);
var destRepos = await gitClient.GetRepositoriesAsync(project: destProjectName);
foreach (var r in sourceRepos)
{
    var destRepoName = $"{prefix}{r.Name}";

    Console.WriteLine($"Creating empty repo at '{destProjectName}/{destRepoName}'");
    var repo = destRepos.SingleOrDefault(rr => rr.Name == destRepoName);
    if (repo == null)
    {
        repo = new GitRepository { Name = destRepoName, };
        repo = await gitClient.CreateRepositoryAsync(repo, destProjectName);
    }

    Console.WriteLine($"Importing '{srcProjectName}/{r.Name}' to '{destProjectName}/{destRepoName}'");
    var imr = new GitImportRequest
    {
        Repository = repo,
        Parameters = new GitImportRequestParameters
        {
            GitSource = new GitImportGitSource { Url = r.RemoteUrl, },
            ServiceEndpointId = new Guid("[the GUId of the service endpoint in the destination project]"),
            DeleteServiceEndpointAfterImportIsDone = false,
            TfvcSource = null
        }
    };
    var result = await gitClient.CreateImportRequestAsync(imr, destProjectName, repo.Id);
}

Note: Alternate Credentials are being (or already) deprecated, but some may still work.
