+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", 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.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", 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.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", 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.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

 # Execute Gradle builds in GitHub Actions workflows
 
-This GitHub Action can be used to execute a Gradle build on any platform supported by GitHub Actions.
+This GitHub Action can be used to configure Gradle and optionally execute a Gradle build on any platform supported by GitHub Actions.
 
-## Usage
+## Use the action to setup Gradle
 
-The following workflow will run `./gradlew build` using the wrapper from the repository on ubuntu, macos and windows. The only prerequisite is to have Java installed: you define the version of Java you need to run the build using the `actions/setup-java` action.
+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.

-## Gradle arguments
+## Why use the `gradle-build-action`?
 
-The `arguments` input can used to pass arbitrary arguments to the `gradle` command line.
+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. 
 
-Here are some valid examples:
-```yaml
-arguments: build
-arguments: check --scan
-arguments: some arbitrary tasks
-arguments: build -PgradleProperty=foo
-arguments: build -DsystemProperty=bar

+However, the `gradle-build-action` offers a number of advantages over this approach:
 
-See `gradle --help` for more information.
+- 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.

-## Caching
+## Gradle Execution
 
-This action provides 3 levels of caching to help speed up your GitHub Actions:
+If the action is configured with an `arguments` input, then Gradle will execute a Gradle build with the arguments provided.
 
-- `distributions` caches any downloaded Gradle zips, including any downloaded [wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html) versions, saving time downloading Gradle distributions ;
-- `dependencies` caches the [dependencies](https://docs.gradle.org/current/userguide/dependency_resolution.html#sub:cache_copy), saving time downloading dependencies ;
-- `configuration` caches the [build configuration](https://docs.gradle.org/nightly/userguide/configuration_cache.html), saving time configuring the build.
-
-Only the first one, caching downloaded distributions, is enabled by default.
-Future versions of this action will enable all caching by default.
-
-You can control which level is enabled as follows:
+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
-distributions-cache-enabled: true
-dependencies-cache-enabled: true
-configuration-cache-enabled: true
-```
-
-NOTE: The `wrapper-cache-enabled` flag has been deprecated, replaced by `distributions-cache-enabled` which enables caching for all downloaded distributions, including Gradle wrapper downloads.
-
-The distributions cache is simple and can't be configured further.
-
-The dependencies and configuration cache will compute a cache key in a best effort manner.
-Keep reading to learn how to better control how they work.
-
-Note that enabling configuration cache without thee dependencies cache is not permitted, since a hit in the configuration cache assumes that dependencies are already present in the local dependencies cache.
-
-### Configuring the dependencies and configuration caches
-
-Both the dependencies and configuration caches use the same default configuration:
-
-They use the following inputs to calculate the cache key:
-
-```text
-**/*.gradle
-**/*.gradle.kts
-**/gradle.properties
-gradle/**
-```
-
-This is a good enough approximation.
-They restore cached state even if there isn't an exact match.
-
-If the defaults don't suit your needs you can override them with the following inputs:
-
-```yaml
-dependencies-cache-key: |
-  **/gradle.properties
-  gradle/dependency-locks/**
-dependencies-cache-exact: true
-configuration-cache-key: |
-  **/gradle.properties
-  gradle/dependency-locks/**
-configuration-cache-exact: true
-```
-
-Coming up with a good cache key isn't trivial and depends on your build.
-The above example isn't realistic.
-Stick to the defaults unless you know what you are doing.
-
-If you happen to use Gradle [dependency locking](https://docs.gradle.org/current/userguide/dependency_locking.html) you can make the dependencies cache more precise with the following configuration:
-
-```yaml
-dependencies-cache-enabled: true
-dependencies-cache-key: gradle/dependency-locks/**
-dependencies-cache-exact: true
-```
-
-## Build scans
-
-If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-build-action` action will emit the link to the published build scan as an output named `build-scan-url`.
-
-You can then use that link in subsequent actions of your workflow.
-

+
+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

+
+### 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
+```
+

+
+```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.
+
+## Caching
+
+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
+
+In some circumstances, it makes sense for a Gradle invocation to read any existing cache entries but not to write changes back.
+For example, you may want to write cache entries for builds on your `main` branch, but not for any PR build invocations.
+
+You can enable read-only caching for any of the caches as follows:
+
+```yaml
+# Only write to the cache for builds on the 'main' branch.
+# Builds on other branches will only read existing entries from the cache.
+cache-read-only: ${{ github.ref != 'refs/heads/main' }}
+```
+
+### 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 action log 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 exising 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.
+
+#### Only write to the cache from the default branch
+
+GitHub cache entries are not shared between builds on different branches. This means that identical cache entries will be stored separately for different branches.
+The exception to the is cache entries for the default (`master`/`main`) branch can be read by actions invoked for other branches.
+
+An easy way to reduce cache usage when you run builds on many different branches is to only permit your default branch to write to the cache,
+with all other branch builds using `cache-read-only`. 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
