VSTS git生成因git子模块而失败

我在VisualStudioTeamServices项目中有一个git回购a和B。 B是a的子模块，在.gitmodules中具有以下配置：

[submodule "my_submodule"]
    path = somefolder/my_submodule
    url = https://xxx.visualstudio.com/xxx/_git/B

如果使用选项Repository/Checkout Submodules进行构建，则会出现以下错误：

在我的maschine works上执行git克隆xxx/a——递归

神奇的文档指出了一个身份验证问题：

但这并没有说明身份验证，甚至在.gitmodules中使用相对路径也不会产生不同的错误消息

有什么想法吗

更新1 出于测试目的，我使用了一个分支。我将更改（添加子模块）合并到master并重试-现在出现以下错误：

该散列是我的子模块的头部-显然可用。

您的.gitmodules文件存在一些问题。通常，文件中的路径应该是您的子模块存储库名称（在您的场景中为“B”）

@eddie msft的评论是正确的：master上有一个同名文件夹。“签出到我的测试分支”未删除该文件夹。当我在本地这样做的时候，这是可行的，但是VS队似乎有一个问题

---

但还有另一个问题：与文档相反，我需要提供子模块（）的完整url。文档说明我应该使用相对url（../B或.././B-这是一个猜测游戏），但这不起作用。

不必，我使用了$git submodule add，以便在文件夹“somefolder/my_submodule”中签出子模块。在我的机器上工作。@kuechlerm那么您可能需要尝试使用相对路径：@kuechlerm可以检查“somefolder”文件夹中是否有一个“my_submodule”文件，该文件与VSTS Web Portal的Repo a中的“path=somefolder/my_submodule”匹配？该错误也可能是由于存储库中的文件已被删除而导致的。请参见此处我的相关回答：，关于在同一组织中重用子模块的主repo凭据。
