Behavior

in: Clone merge request source branch

git clones the source branch of the respective merge request.

Updates the merge request's merge_status which displays nicely in the GitLab UI and allows to only merge changes if they pass the test.

Parameters

• repository: The path of the repository of the merge request's source branch (required)
• status: The new status of the merge request (required, can be either pending, running, success, failed, or canceled)
• labels(string[]): The labels you want add to your merge request
