如何在另一个 git repo 中添加私有 git repo 作为子模块

Question

How to add a private git repository as a submodule in another git repository?

locally when i do git submodule update it works fine, but in the github action runner, it fails with error stating url not found at the checkout step.

Here's how i have configured my workflow file.

jobs:
  update_submodules:
    runs-on: ubuntu-latest

    steps:
      # Checkout the repository to the GitHub Actions runner
      - name: Checkout
        uses: actions/checkout@v3
        with:
          submodules: true

      # - name: Clone submodule
      #   run: git submodule update --init --recursive

      - name: Pull & update submodules recursively
        run: |
          git submodule update --init --recursive
          git submodule update --recursive --remote

It fails in the second step.

You could not have to code the submodule update init , as it is an option of the action/checkout itself.

For instance, actions/checkout issue 116 shows:

• Generate PAT: https://github.com/settings/tokens
• And add the secret: https://github.com/<-- username -->/<-- repo -->/settings/secrets/new , give it a unique name say MY_REPO_PAT .
• Configure action as follows:

 steps: - name: Checkout uses: actions/checkout@v2 with: token: ${{ secrets.MY_REPO_PAT }} submodules: recursive

Or (alternative), issue 287 :

I have a solution that doesn't require personal access tokens but keeps the reference to the child repo commit in one place (using git submodules)

 - name: clone submodule uses: actions/checkout@v2 with: repository: <org name>/<repo name> path: path ssh-key: ${{ secrets.SSH_KEY }} persist-credentials: true - name: checkout submodule run: | git submodule init git submodule update

Although the action checks out master , the git submodule commands check out the correct commit, this avoids having to keep the ref in github actions.
