To duplicate an open issue, you must have triage access to the repository that contains the original issue and to the destination repository. The destination repository must allow blank issues. See 组织的存储库角色.
When you duplicate an issue, a new issue is created with the original issue’s title, description, assignees, type, labels, milestones, and projects prefilled, as long as those fields exist or are available in the destination repository. Labels and milestones are retained if they are present in the target repository, with labels matching by name and milestones matching by both name and due date. The original issue remains unchanged.
People or teams mentioned in the original issue will not receive notifications about the duplication. The new issue will have its own URL and can be edited before being created. If you attempt to duplicate an issue to a repository where you do not have triage access, the option will not be available.
