# Gradle on GitHub Actions

version 9.7.0-20260602012325+0000

This page is a reference for integrating Gradle with GitHub Actions using the official `gradle/actions`.

## Available actions

The `gradle/actions` repository publishes three composable actions. All examples on this page target the current major version, `v6`.

Action | Purpose
--- | ---
`gradle/actions/setup-gradle` | Configures the runner for Gradle builds. Restores and saves the Gradle User Home cache, validates the Gradle Wrapper, and captures Build Scan® links in the job summary.
`gradle/actions/dependency-submission` | Generates a dependency graph for the project and submits it to the GitHub Dependency Submission API, enabling Dependabot alerts and supply-chain security features.
`gradle/actions/wrapper-validation` | Validates the checksum of every `gradle-wrapper.jar` in the repository. `setup-gradle` runs this check automatically; use this action standalone when you do not need the rest of `setup-gradle`.

| `gradle/actions/setup-gradle` is the successor to the deprecated `gradle/gradle-build-action`. New projects should use `gradle/actions/setup-gradle@v6`.

## Configuring builds with `setup-gradle`

A minimal workflow that builds a Gradle project and publishes a Build Scan:

    name: Build

    on: [push, pull_request]

    jobs:
      build:
        runs-on: ubuntu-latest
        steps:
          - uses: actions/checkout@v4

          - uses: actions/setup-java@v4
            with:
              distribution: temurin
              java-version: 21

          - uses: gradle/actions/setup-gradle@v6
            with:
              build-scan-publish: true
              build-scan-terms-of-use-url: "https://gradle.com/terms-of-service"
              build-scan-terms-of-use-agree: "yes"

          - run: ./gradlew build

### Key inputs

Input | Description
--- | ---
`gradle-version` | Gradle version to provision on the runner. Accepts an explicit version (e.g. `8.14`) or an alias: `wrapper` (default), `current`, `release-candidate`, `nightly`, `release-nightly`.
`cache-provider` | Caching backend. `enhanced` (default, optimized proprietary cache — free for public repos) or `basic` (open-source wrapper over `actions/cache`). New in v6.
`cache-disabled` | Set to `true` to disable all caching.
`cache-read-only` | Read cache entries but do not write them back. Typical for feature branches so only the default branch updates the cache.
`cache-write-only` | Start with a clean Gradle User Home and save state at job end. Useful for seeding a fresh cache.
`cache-cleanup` | Purge unused files from Gradle User Home before saving. One of `always`, `on-success` (default), or `never`.
`cache-encryption-key` | Base64-encoded AES key used to encrypt configuration-cache entries, which may contain credentials. Required to cache the configuration cache across jobs.
`gradle-home-cache-includes` / `gradle-home-cache-excludes` | Glob patterns that add to or subtract from the set of Gradle User Home paths that are cached.
`build-scan-publish` | When `true`, publishes a Build Scan for every Gradle invocation in the job.
`build-scan-terms-of-use-url` / `build-scan-terms-of-use-agree` | Required when `build-scan-publish` is enabled. Set the URL to `https://gradle.com/terms-of-service` and agreement to `yes`.
`develocity-access-key` | Access key for publishing Build Scans to a private Develocity server. Provide via `secrets`.
`add-job-summary` | Controls the GitHub Actions job summary produced by the action: `always` (default), `on-failure`, or `never`.
`add-job-summary-as-pr-comment` | Mirror the job summary as a pull-request comment: `never` (default), `on-failure`, or `always`.

See the `setup-gradle` documentation for the complete input reference.

### Caching behavior

`setup-gradle` automatically saves and restores the Gradle User Home (`~/.gradle`), which contains the Gradle distribution, resolved dependencies, and the local build cache. A cache entry is written at job completion when the job is a push to the default branch; other jobs restore from existing entries.

Starting with version 6.1.0, the default cache backend is the enhanced provider, which offers higher hit rates than the standard GitHub Actions cache. Set `cache-provider: basic` to use the fully open-source implementation over `actions/cache`.

## Submitting dependency graphs

The `dependency-submission` action runs the Gradle build in a dedicated mode that captures the resolved dependency graph, then submits it to GitHub via the Dependency Submission API. Once submitted, the graph powers Dependabot alerts and the Insights → Dependency graph view.

    name: Dependency Submission

    on:
      push:
        branches: [main]

    permissions:
      contents: write

    jobs:
      dependency-submission:
        runs-on: ubuntu-latest
        steps:
          - uses: actions/checkout@v4

          - uses: actions/setup-java@v4
            with:
              distribution: temurin
              java-version: 21

          - uses: gradle/actions/dependency-submission@v6
            with:
              build-scan-publish: true
              build-scan-terms-of-use-url: "https://gradle.com/terms-of-service"
              build-scan-terms-of-use-agree: "yes"

| The workflow requires `contents: write` permission to submit the graph. Both Dependency graph and Dependabot alerts must be enabled in repository settings.

### Key inputs

Input | Description
--- | ---
`dependency-graph` | What to do with the generated graph: `generate-and-submit` (default), `generate-and-upload` (save as workflow artifact only), `generate-submit-and-upload`, or `clear` to remove previously submitted graphs.
`dependency-graph-continue-on-failure` | If `true`, a failure to generate or submit the graph does not fail the job.
`dependency-graph-include-projects` / `-exclude-projects` | Regex filters on Gradle subproject paths, e.g. `:app` or `:libs:.*`.
`dependency-graph-include-configurations` / `-exclude-configurations` | Regex filters on configuration names, e.g. exclude `testRuntimeClasspath` from the submitted graph.
`dependency-resolution-task` | Task used to resolve dependencies. Defaults to the built-in `GitHubDependencyGraphPlugin` resolution; override only if a custom task is required.
`additional-arguments` | Extra arguments appended to the Gradle invocation (for example `--no-configuration-cache`).
`build-root-directory` | Path to the Gradle build if it is not at the repository root.
`artifact-retention-days` | Retention for uploaded dependency-graph artifacts (default `30`).

See the `dependency-submission` documentation for the complete input reference.

## Validating the Gradle Wrapper

`setup-gradle` validates every `gradle-wrapper.jar` in the repository on each run. Projects that do not otherwise use `setup-gradle` (for example, those building with a pre-installed Gradle distribution) can run the standalone action:

    - uses: gradle/actions/wrapper-validation@v6

## Build Scans in job summaries

When `setup-gradle` or `dependency-submission` detects a published Build Scan, it appends the scan link and a task-execution summary to the GitHub Actions job summary. Use `add-job-summary-as-pr-comment: on-failure` to surface the same information on the pull request when a build fails.

## Matrix builds

For matrix builds, use `cache-read-only: true` on non-primary matrix legs so only one leg writes to the cache:

    strategy:
      matrix:
        java: [17, 21]
    steps:
      - uses: gradle/actions/setup-gradle@v6
        with:
          cache-read-only: ${{ matrix.java != 21 }}
