-This GitHub Action can be used to configure Gradle on any platform supported by GitHub Actions.
+## Use the action to setup Gradle
 
-## Example usage
+If you have an existing workflow invoking Gradle, you can add an initial "Setup Gradle" Step to benefit from caching, 
+build-scan capture and other features of the gradle-build-action.
+
+All subsequent Gradle invocations will benefit from this initial setup, via `init` scripts added to the Gradle User Home.

 ```
 
-See the [full setup-gradle documentation](https://github.com/gradle/actions/tree/main/setup-gradle) for more advanced usage scenarios. 
+## Why use the `gradle-build-action`?
+
+It is possible to directly invoke Gradle in your workflow, and the `actions/setup-java@v3` action provides a simple way to cache Gradle dependencies. 
+
+However, the `gradle-build-action` offers a number of advantages over this approach:
+
+- Easily [run the build with different versions of Gradle](#download-install-and-use-a-specific-gradle-version) using the `gradle-version` parameter. Gradle distributions are automatically downloaded and cached. 
+- More sophisticated and more efficient caching of Gradle User Home between invocations, compared to `setup-java` and most custom configurations using `actions/cache`. [More details below](#caching).
+- Detailed reporting of cache usage and cache configuration options allow you to [optimize the use of the GitHub actions cache](#optimizing-cache-effectiveness).
+- [Automatic capture of build scan links](#build-scans) from the build, making these easier to locate for workflow run.
+
+The `gradle-build-action` is designed to provide these benefits with minimal configuration. 
+These features work both when Gradle is executed via the `gradle-build-action` and for any Gradle execution in subsequent steps.
+
+When using `gradle-build-action` we recommend that you _not_ use `actions/cache` or `actions/setup-java@v3` to explicitly cache the Gradle User Home. Doing so may interfere with the caching provided by this action.
+
+## Use a specific Gradle version
+
+The `gradle-build-action` can download and install a specified Gradle version, adding this installed version to the PATH.
+Downloaded Gradle versions are stored in the GitHub Actions cache, to avoid requiring downloading again later.
+
+```yaml
+ - uses: gradle/gradle-build-action@v2
+   with:
+     gradle-version: 6.5
+```
+
+The `gradle-version` parameter can be set to any valid Gradle version.
+
+Moreover, you can use the following aliases:
+
+| Alias | Selects |
+| --- |---|
+| `wrapper`           | The Gradle wrapper's version (default, useful for matrix builds) |
+| `current`           | The current [stable release](https://gradle.org/install/) |
+| `release-candidate` | The current [release candidate](https://gradle.org/release-candidate/) if any, otherwise fallback to `current` |
+| `nightly`           | The latest [nightly](https://gradle.org/nightly/), fails if none. |
+| `release-nightly`   | The latest [release nightly](https://gradle.org/release-nightly/), fails if none.      |
+
+This can be handy to automatically verify your build works with the latest release candidate of Gradle:
+
+```yaml
+name: Test latest Gradle RC
+on:
+  schedule:
+    - cron: 0 0 * * * # daily
+jobs:
+  gradle-rc:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v3
+    - uses: actions/setup-java@v3
+      with:
+        distribution: temurin
+        java-version: 11
+    - uses: gradle/gradle-build-action@v2
+      with:
+        gradle-version: release-candidate
+    - run: gradle build --dry-run # just test build configuration
+```
+
+## Gradle Execution
+
+If the action is configured with an `arguments` input, then Gradle will execute a Gradle build with the arguments provided.
+
+If no `arguments` are provided, the action will not execute Gradle, but will still cache Gradle state and configure build-scan capture for all subsequent Gradle executions.
+
+```yaml
+name: Run Gradle on PRs
+on: pull_request
+jobs:
+  gradle:
+    strategy:
+      matrix:
+        os: [ubuntu-latest, macos-latest, windows-latest]
+    runs-on: ${{ matrix.os }}
+    steps:
+    - uses: actions/checkout@v3
+    - uses: actions/setup-java@v3
+      with:
+        distribution: temurin
+        java-version: 11
+    
+    - name: Setup and execute Gradle 'test' task
+      uses: gradle/gradle-build-action@v2
+      with:
+        arguments: test
+```
+
+### Multiple Gradle executions in the same Job
+
+It is possible to configure multiple Gradle executions to run sequentially in the same job. 
+The initial Action step will perform the Gradle setup.
+
+```yaml
+- uses: gradle/gradle-build-action@v2
+  with:
+    arguments: assemble
+- uses: gradle/gradle-build-action@v2
+  with:
+    arguments: check
+```
+
+### Gradle command-line arguments
+
+The `arguments` input can be used to pass arbitrary arguments to the `gradle` command line.
+Arguments can be supplied in a single line, or as a multi-line input.
+
+Here are some valid examples:
+```yaml
+arguments: build
+arguments: check --scan
+arguments: some arbitrary tasks
+arguments: build -PgradleProperty=foo
+arguments: |
+    build
+    --scan
+    -PgradleProperty=foo
+    -DsystemProperty=bar
+```
+
+If you need to pass environment variables, use the GitHub Actions workflow syntax:
+
+```yaml
+- uses: gradle/gradle-build-action@v2
+  env:
+    CI: true
+  with:
+    arguments: build
+```
+
+### Gradle build located in a subdirectory
+
+By default, the action will execute Gradle in the root directory of your project. 
+Use the `build-root-directory` input to target a Gradle build in a subdirectory.
+
+```yaml
+- uses: gradle/gradle-build-action@v2
+  with:
+    arguments: build
+    build-root-directory: some/subdirectory
+```
+
+### Using a specific Gradle executable
+
+The action will first look for a Gradle wrapper script in the root directory of your project. 
+If not found, `gradle` will be executed from the PATH.
+Use the `gradle-executable` input to execute using a specific Gradle installation.
+
+```yaml
+ - uses: gradle/gradle-build-action@v2
+   with:
+     arguments: build
+     gradle-executable: /path/to/installed/gradle
+```
+
+This mechanism can also be used to target a Gradle wrapper script that is located in a non-default location.
+

+By default, this action aims to cache any and all reusable state that may be speed up a subsequent build invocation. 
+
+The state that is cached includes:
+- Any distributions downloaded to satisfy a `gradle-version` parameter ;
+- A subset of the Gradle User Home directory, including downloaded dependencies, wrapper distributions, and the local build cache ;
+- Any [configuration-cache](https://docs.gradle.org/nightly/userguide/configuration_cache.html) data stored in the project `.gradle` directory. (Only supported for Gradle 7 or higher.)
+
+To reduce the space required for caching, this action makes a best effort to reduce duplication in cache entries.
+
+Caching is enabled by default. You can disable caching for the action as follows:
+```yaml
+cache-disabled: true
+```
+### Cache keys
+
+Distributions downloaded to satisfy a `gradle-version` parameter are stored outside of Gradle User Home and cached separately. The cache key is unique to the downloaded distribution and will not change over time.
+
+The state of the Gradle User Home and configuration-cache are highly dependent on the Gradle execution, so the cache key is composed of the current commit hash and the GitHub actions job id.
+As such, the cache key is likely to change on each subsequent run of GitHub actions. 
+This allows the most recent state to always be available in the GitHub actions cache.
+
+To reduce duplication between cache entries, certain artifacts are cached independently based on their identity.
+Artifacts that are cached independently include downloaded dependencies, downloaded wrapper distributions and generated Gradle API jars.
+For example, this means that all jobs executing a particular version of the Gradle wrapper will share common entries for wrapper distributions and for generated Gradle API jars.
+
+### Using the caches read-only
+
+By default, the `gradle-build-action` will only write to the cache from Jobs on the default (`main`/`master`) branch.
+Jobs on other branches will read entries from the cache but will not write updated entries. 
+See [Optimizing cache effectiveness](#optimizing-cache-effectiveness) for a more detailed explanation.
+
+In some circumstances it makes sense to change this default, and to configure a workflow Job to read existing cache entries but not to write changes back.
+
+You can configure read-only caching for the `gradle-build-action` as follows:
+
+```yaml
+# Only write to the cache for builds on the 'main' and 'release' branches. (Default is 'main' only.)
+# Builds on other branches will only read existing entries from the cache.
+cache-read-only: ${{ github.ref != 'refs/heads/main' && github.ref != 'refs/heads/release' }}
+```
+
+### Stopping the Gradle daemon
+
+By default, the action will stop all running Gradle daemons in the post-action step, prior to saving the Gradle User Home state. 
+This allows for any Gradle User Home cleanup to occur, and avoid file-locking issues on Windows.
+
+If caching is unavailable or the cache is in read-only mode, the daemon will not be stopped and will continue running after the job is completed.
+
+### Gradle User Home cache tuning
+
+As well as any wrapper distributions, the action will attempt to save and restore the `caches` and `notifications` directories from Gradle User Home.
+
+The contents to be cached can be fine tuned by including and excluding certain paths with Gradle User Home.
+
+```yaml
+# Cache downloaded JDKs in addition to the default directories.
+gradle-home-cache-includes: |
+    caches
+    notifications
+    jdks
+# Exclude the local build-cache from the directories cached.
+gradle-home-cache-excludes: |
+    caches/build-cache-1
+```
+
+You can specify any number of fixed paths or patterns to include or exclude. 
+File pattern support is documented at https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#patterns-to-match-file-paths.
+
+### Cache debugging and analysis
+
+Gradle User Home state will be restored from the cache during the first `gradle-build-action` step for any workflow job. 
+This state will be saved back to the cache at the end of the job, after all Gradle executions have completed.
+A report of all cache entries restored and saved is printed to the Job Summary when saving the cache entries. 
+This report can provide valuable insignt into how much cache space is being used.
+
+It is possible to enable additional debug logging for cache operations. You do via the `GRADLE_BUILD_ACTION_CACHE_DEBUG_ENABLED` environment variable:
+
+```yaml
+env:
+  GRADLE_BUILD_ACTION_CACHE_DEBUG_ENABLED: true
+```
+
+Note that this setting will also prevent certain cache operations from running in parallel, further assisting with debugging.
+
+### Optimizing cache effectiveness
+
+Cache storage space for GitHub actions is limited, and writing new cache entries can trigger the deletion of existing entries.
+Eviction of shared cache entries can reduce cache effectiveness, slowing down your `gradle-build-action` steps.
+
+There are a number of actions you can take if your cache use is less effective due to entry eviction.
+
+#### Select branches that should write to the cache
+
+GitHub cache entries are not shared between builds on different branches. 
+This means that each PR branch will have it's own Gradle User Home cache, and will not benefit from cache entries written by other PR branches.
+An exception to this is that cache entries written in parent and upstream branches are visible to child branches, and cache entries for the default (`master`/`main`) branch can be read by actions invoked for any other branch.
+
+By default, the `gradle-build-action` will only _write_ to the cache for builds run on the default (`master`/`main`) branch. 
+Jobs run on other branches will only read from the cache. In most cases, this is the desired behaviour, 
+because Jobs run against other branches will benefit from the cache Gradle User Home from `main`, 
+without writing private cache entries that could lead to evicting shared entries.
+
+If you have other long-lived development branches that would benefit from writing to the cache, 
+you can configure these by overriding the `cache-read-only` action parameter. 
+See [Using the caches read-only](#using-the-caches-read-only) for more details.
+
+Similarly, you could use `cache-read-only` for certain jobs in the workflow, and instead have these jobs reuse the cache content from upstream jobs.
+
+#### Exclude content from Gradle User Home cache
+
+Each build is different, and some builds produce more Gradle User Home content than others.
+[Cache debugging ](#cache-debugging-and-analysis) can provide insight into which cache entries are the largest,
+and you can selectively [exclude content using `gradle-home-cache-exclude`](#gradle-user-home-cache-tuning).
+
+## Saving build outputs
+
+By default, a GitHub Actions workflow using `gradle-build-action` will record the log output and any Build Scan links for your build,
+but any output files generated by the build will not be saved.
+
+To save selected files from your build execution, you can use the core [Upload-Artifact](https://github.com/actions/upload-artifact) action.
+For example:
+
+```yaml
+jobs:   
+  gradle:
+    runs-on: ubuntu-latest
+    steps:
+    - name: Checkout project sources
+      uses: actions/checkout@v3
+    - name: Setup Gradle
+      uses: gradle/gradle-build-action@v2
+    - name: Run build with Gradle wrapper
+      run: ./gradlew build --scan
+    - name: Upload build reports
+      uses: actions/upload-artifact@v3
+      with:
+        name: build-reports
+        path: build/reports/
+```
+
+## Build scans
+
+If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-build-action` action will:
+- Add a notice with the link to the GitHub Actions user interface
+- For each step that executes Gradle, adds the link to the published build scan as a Step output named `build-scan-url`.
+
+You can then use that link in subsequent actions of your workflow. For example:
+
+```yaml
+# .github/workflows/gradle-build-pr.yml
+name: Run Gradle on PRs
+on: pull_request
+jobs:
+  gradle:
+    runs-on: ubuntu-latest
+    steps:
+    - name: Checkout project sources
+      uses: actions/checkout@v3
+    - name: Setup Gradle
+      uses: gradle/gradle-build-action@v2
+    - name: Run build with Gradle wrapper
+      id: gradle
+      run: ./gradlew build --scan
+    - name: "Add build scan URL as PR comment"
+      uses: actions/github-script@v5
+      if: github.event_name == 'pull_request' && failure()
+      with:
+        github-token: ${{secrets.GITHUB_TOKEN}}
+        script: |
+          github.rest.issues.createComment({
+            issue_number: context.issue.number,
+            owner: context.repo.owner,
+            repo: context.repo.repo,
+            body: '❌ ${{ github.workflow }} failed: ${{ steps.gradle.outputs.build-scan-url }}'
+          })
+```
+
+## Support for GitHub Enterprise Server (GHES)
+
+You can use the `gradle-build-action` on GitHub Enterprise Server, and benefit from the improved integration with Gradle. Depending on the version of GHES you are running, certain features may be limited:
+- Build scan links are captured and displayed in the GitHub Actions UI
+- Easily run your build with different versions of Gradle
+- Save/restore of Gradle User Home (requires GHES v3.5+ : GitHub Actions cache was introduced in GHES 3.5)
+- Support for GitHub Actions Job Summary is not yet available in any version of GHES. Instead of producing a Job Summary, the build-results summary and caching report will be written to the workflow log, as part of the post-action step.

+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.

+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
