How can I configure Azure DevOps pipelines to build projects with Git submodules?

Git submodules allow teams to manage dependencies across repositories, but configuring Azure DevOps pipelines to handle projects with submodules requires specific steps. What is the recommended way to configure Azure DevOps pipelines to clone and build projects that include Git submodules? Are there any common pitfalls or advanced configuration options to consider when working with submodules in pipelines?

Answer 1

Setting up Azure DevOps pipelines to use Git submodules for project development:

Enable Submodule Checkout: Use the submodules option in your pipeline YAML to define the checkout step:
Authenticate Submodules: If submodules need to be authenticated, make sure the right credentials are in the pipeline. Use a credential manager or personal access token (PAT) for HTTPS submodules.
Revise Submodules:
Use the git submodule update --init --recursive command to initialize and update submodules during the pipeline.
Cache Submodules:
To optimize builds, cache submodules between runs by saving them as pipeline artifacts.
Build and Test Submodule Projects:
Ensure your build script or pipeline includes the necessary steps to compile and test the submodule code.

By properly configuring the checkout process and addressing authentication, you can seamlessly integrate submodules into your Azure DevOps pipelines.
