[![Build and Test](https://github.com/actions/checkout/actions/workflows/test.yml/badge.svg)](https://github.com/actions/checkout/actions/workflows/test.yml)

# Checkout V5

Checkout v5 now supports Node.js 24

# Checkout V4

This action checks-out your repository under `$GITHUB_WORKSPACE`, so your workflow can access it.

Only a single commit is fetched by default, for the ref/SHA that triggered the workflow. Set `fetch-depth: 0` to fetch all history for all branches and tags. Refer [here](https://docs.github.com/actions/using-workflows/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.

The auth token is persisted in the local git config. This enables your scripts to run authenticated git commands. The token is removed during post-job cleanup. Set `persist-credentials: false` to opt-out.

When Git 2.18 or higher is not in your PATH, falls back to the REST API to download the files.

### Note

Thank you for your interest in this GitHub action, however, right now we are not taking contributions. 

We continue to focus our resources on strategic areas that help our customers be successful while making developers' lives easier. While GitHub Actions remains a key part of this vision, we are allocating resources towards other areas of Actions and are not taking contributions to this repository at this time. The GitHub public roadmap is the best place to follow along for any updates on features we’re working on and what stage they’re in.

We are taking the following steps to better direct requests related to GitHub Actions, including:

1. We will be directing questions and support requests to our [Community Discussions area](https://github.com/orgs/community/discussions/categories/actions)

2. High Priority bugs can be reported through Community Discussions or you can report these to our support team https://support.github.com/contact/bug-report.

3. Security Issues should be handled as per our [security.md](security.md)

We will still provide security updates for this project and fix major breaking changes during this time.

You are welcome to still raise bugs in this repo.

# Usage

<!-- start usage -->
```yaml
- uses: actions/checkout@v5
  with:
    # Repository name with owner. For example, actions/checkout
    # Default: ${{ github.repository }}

    # triggered a workflow, this defaults to the reference or SHA for that event.
    # Otherwise, uses the default branch.

    # We recommend using a service account with the least permissions necessary. Also
    # when generating a new PAT, select the least scopes necessary.

## Fetch only the root files

```yaml
- uses: actions/checkout@v5
  with:
    sparse-checkout: .
```

## Fetch only the root files and `.github` and `src` folder

```yaml
- uses: actions/checkout@v5
  with:
    sparse-checkout: |
      .github
      src
```

## Fetch only a single file

```yaml
- uses: actions/checkout@v5
  with:
    sparse-checkout: |
      README.md
    sparse-checkout-cone-mode: false
```

## Fetch all history for all tags and branches

```yaml
- uses: actions/checkout@v5
  with:
    fetch-depth: 0
```

## Checkout a different branch

```yaml
- uses: actions/checkout@v5
  with:
    ref: my-branch
```

## Checkout HEAD^

```yaml
- uses: actions/checkout@v5
  with:
    fetch-depth: 2
- run: git checkout HEAD^
```

## Checkout multiple repos (side by side)

```yaml
- name: Checkout
  uses: actions/checkout@v5
  with:
    path: main

- name: Checkout tools repo
  uses: actions/checkout@v5
  with:
    repository: my-org/my-tools
    path: my-tools
```
> - If your secondary repository is private or internal you will need to add the option noted in [Checkout multiple repos (private)](#Checkout-multiple-repos-private)

## Checkout multiple repos (nested)

```yaml
- name: Checkout
  uses: actions/checkout@v5

- name: Checkout tools repo
  uses: actions/checkout@v5
  with:
    repository: my-org/my-tools
    path: my-tools
```
> - If your secondary repository is private or internal you will need to add the option noted in [Checkout multiple repos (private)](#Checkout-multiple-repos-private)

## Checkout multiple repos (private)

```yaml
- name: Checkout
  uses: actions/checkout@v5
  with:
    path: main

- name: Checkout private tools
  uses: actions/checkout@v5
  with:
    repository: my-org/my-private-tools
    token: ${{ secrets.GH_PAT }} # `GH_PAT` is a secret that contains your PAT
    path: my-tools
```

> - `${{ github.token }}` is scoped to the current repository, so if you want to checkout a different repository that is private you will need to provide your own [PAT](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line).


## Checkout pull request HEAD commit instead of merge commit

```yaml
- uses: actions/checkout@v5
  with:
    ref: ${{ github.event.pull_request.head.sha }}
```

## Checkout pull request on closed event

```yaml
on:
  pull_request:
    branches: [main]
    types: [opened, synchronize, closed]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
```

## Push a commit using the built-in token

```yaml
on: push
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
      - run: |
          date > generated.txt
          # Note: the following account information will not work on GHES
          git config user.name "github-actions[bot]"
          git config user.email "41898282+github-actions[bot]@users.noreply.github.com"
          git add .
          git commit -m "generated"
          git push
```
*NOTE:* The user email is `{user.id}+{user.login}@users.noreply.github.com`. See users API: https://api.github.com/users/github-actions%5Bbot%5D

## Push a commit to a PR using the built-in token

In a pull request trigger, `ref` is required as GitHub Actions checks out in detached HEAD mode, meaning it doesn’t check out your branch by default.

```yaml
on: pull_request
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
        with:
          ref: ${{ github.head_ref }}
      - run: |
          date > generated.txt
          # Note: the following account information will not work on GHES
          git config user.name "github-actions[bot]"
          git config user.email "41898282+github-actions[bot]@users.noreply.github.com"
          git add .
          git commit -m "generated"
          git push
```

*NOTE:* The user email is `{user.id}+{user.login}@users.noreply.github.com`. See users API: https://api.github.com/users/github-actions%5Bbot%5D

# Recommended permissions

When using the `checkout` action in your GitHub Actions workflow, it is recommended to set the following `GITHUB_TOKEN` permissions to ensure proper functionality, unless alternative auth is provided via the `token` or `ssh-key` inputs:

```yaml
permissions:
  contents: read
```
