Fetching multiple TFS git repo sources with git submodules

问题

I'm facing an issue while trying to access different git sources in TFS Build.

I have 2 repos Test1 & Test2 - https://tfs.org.com:8080/tfs/collection/project/_git/Test1 (& Test2). Under Test2, I added a sample.txt & .gitmodules file.

.GitModules file has a cmd - git submodule add https://tfs.org.com:8080/tfs/collection/project/_git/Test1 (Since I want to checkout Test1 contents too while triggering Test2 repo)

Now in Build def (which builds Test2) I checked the option (Checkout Submodules) - and triggered the build. But I don't see Test1's content was checkout in build server. How can I achieve this ?

Note: I have tried with other option that I found online - but no luck.

[submodule "Test1"]
    path = Test1
    url = https://tfs.org.com:8080/tfs/collection/project/_git/Test1

(The above one is a POC's that I'm testing to make it work in our actual environment, i.e, Azure DevOps - accessing TFS with OtherGit service connection to build and release)

Here is the build Log for Get Sources:

回答1:

You must select the option to download submodules.

In YAML you must add an explicit checkout step

steps:
- checkout: self
  submodules: true

回答2:

I followed the steps below and it worked as expected:

Create two repositories and initialize.
Use "git submodule add" command.
Now I have a .gitmodules file and a test1 file in my test2 repository
Create a pipeline and select the "Checkout submodules" option.
I can see the following logs after running pipelines.
