Team Services文档（https://www.visualstudio.com/en-us/docs/build/define/repository#what-kinds-of-submodules-can-i-check-out）指出我可以$ git add submodule如果
他们举了一个例子：
git submodule add /../../submodule.git mymodule
如果我在同一个项目中引用git repo，比如
git submodule add ./../other-repo mymodule
它解决了正确的回购，但希望我提供凭证。构建失败，并显示以下消息：
Cloning into 'mymodule'...
fatal: could not read Username for 'https://xxx.visualstudio.com': Invalid argument
提供带有凭据（https://user:password@xxx.visualstudio.com/..。）的完整网址有效，但IMO是一个糟糕的解决方案。
文档表明，这应该与相对网址一起使用，而不使用凭据。我错了吗？

我无法回答这个问题。文档错误/不清楚，我选择查看像@ eddie-msft这样的子模块说 - 但要注意：VSTS git build fails with git submodule

还请检查两个存储库的路径。如果项目中只有两个存储库，则第一个创建的存储库A的路径为：
https://xxxx.visualstudio.com/_git/A
第二个创建回购B的路径是：
https://xxxx.visualstudio.com/A/_git/B
在这种情况下，您需要使用如下的相对路径：
../../A/_git/B

我从Submodules - Azure Repos获悉，在以下情况下存在问题：
如果您按照上述部分中的说明限制了工作访问令牌，则将无法执行此操作。
我自己只尝试过nr 1，它对我们有用。
Limit job authorization scope to referenced Azure DevOps repositories，这将授予对所有DevOps存储库的管道访问权限。../MySubmoduleRepo或../../../OtherProject/_git/MySubmoduleRepo。https://stackoverflow.com/a/63593883/134761
steps:
- checkout: self
submodules: false
persistCredentials : true
- powershell: |
$header = "AUTHORIZATION: bearer $(System.AccessToken)"
git -c http.extraheader="$header" submodule sync
git -c http.extraheader="$header" submodule update --init --force --depth=1
