+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+

-# GitHub Actions for Gradle builds
+# Execute Gradle commands in GitHub Actions workflows
 
-This repository contains a set of GitHub Actions that are useful for building Gradle projects on GitHub.
+This GitHub Action can be used to run arbitrary Gradle commands on any platform supported by GitHub Actions.
 
-## `gradle/actions/setup-gradle`
+You might also be interested by the related [Gradle Plugin](https://github.com/eskatos/gradle-github-actions-plugin) that allows your build to easily get GitHub Actions environment and tag Gradle Build Scans accordingly.
+
+## Usage
+
+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 can define the version you need to run the build using the `actions/setup-java` action.
 
-A simple wrapper around `gradle/gradle-build-action`, removing the deprecated `arguments` parameter (and thus removing the ability to _execute_ gradle).
-The intention is to eventually deprecate `gradle-build-action` with this being the replacement.
 
-### Example usage
 
 ```yaml
-name: Build
-
-on:
-  workflow_dispatch:
-  push:
-
+# .github/workflows/gradle-build-pr.yml
+name: Run Gradle on PRs
+on: pull_request
 jobs:
-  build:
-    runs-on: ubuntu-latest
+  gradle:
+    strategy:
+      matrix:
+        os: [ubuntu-latest, macos-latest, windows-latest]
+    runs-on: ${{ matrix.os }}
     steps:
-    - name: Checkout sources
-      uses: actions/checkout@v4
-    - name: Setup Gradle
-      uses: gradle/actions/setup-gradle@v0
-    - name: Build with Gradle
-      run: ./gradlew build
+    - uses: actions/checkout@v1
+    - uses: actions/setup-java@v1
+      with:
+        java-version: 11
+    - uses: eskatos/gradle-command-action@v1
+      with:
+        arguments: build
 ```
 
-## `gradle/actions/dependency-submission`
+## Gradle arguments
 
-Generates and submits a dependency graph for a Gradle project. This action is designed to be used in a standalone workflow.
-The intention is to provide a simple, standardised way to enable Dependency Graph support for Gradle repositories,
-with a long-term goal of having this functionality enabled by default for Gradle projects on GitHub.
+The `arguments` input can used to pass arbitrary arguments to the `gradle` command line.
 
-### Example usage
+Here are some valid examples:
 ```yaml
-name: Dependency Submission
+arguments: build
+arguments: check --scan
+arguments: some arbitrary tasks
+arguments: build -PgradleProperty=foo
+arguments: build -DsystemProperty=bar
+....
+```
 
+See `gradle --help` for more information.
+
+If you need to pass environment variables, simply use the GitHub Actions workflow syntax:
+
+```yaml
+- uses: eskatos/gradle-command-action@v1
+  env:
+    CI: true
+```
+
+## Run a build from a different directory
+
+```yaml
+- uses: eskatos/gradle-command-action@v1
+  with:
+    build-root-directory: some/subdirectory
+```
+
+## Use a Gradle wrapper from a different directory
+ 
+```yaml
+ - uses: eskatos/gradle-command-action@v1
+   with:
+     wrapper-directory: path/to/wrapper-directory
+ ```
+
+## Use a specific `gradle` executable
+
+```yaml
+ - uses: eskatos/gradle-command-action@v1
+   with:
+     gradle-executable: path/to/gradle
+```
+
+## Setup and use a declared Gradle version
+
+```yaml
+ - uses: eskatos/gradle-command-action@v1
+   with:
+     gradle-version: 5.6.2
+```
+
+`gradle-version` 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/) |
+| `rc`      | 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, for example, automatically test your build with the next Gradle version once a release candidate is out:
+
+```yaml
+# .github/workflows/test-gradle-rc.yml
+name: Test latest Gradle RC
 on:
-  workflow_dispatch:
-  push:
-    branches:
-    - main
-
-permissions:
-  contents: write
-
+  schedule:
+    - cron: 0 0 * * * # daily
 jobs:
-  dependency-submission:
+  gradle-rc:
     runs-on: ubuntu-latest
     steps:
-    - name: Checkout sources
-      uses: actions/checkout@v4
-    - name: Generate and submit dependency graph
-      uses: gradle/actions/dependency-submission@v0
+    - uses: actions/checkout@v1
+    - uses: actions/setup-java@v1
+      with:
+        java-version: 11
+    - uses: eskatos/gradle-command-action@v1
+      with:
+        gradle-version: rc
+        arguments: build --dry-run # just test build configuration
+```
+
+# Build scans
+
+If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-command-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.
+
+For example:
+
+```yaml
+# .github/workflows/gradle-build-pr.yml
+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@v1
+    - uses: actions/setup-java@v1
+      with:
+        java-version: 11
+    - uses: eskatos/gradle-command-action@v1
+      with:
+        arguments: build
+      id: gradle
+    - uses: example/action-that-comments-on-the-pr@v0
+      if: failure()
+      with:
+        comment: Build failed ${{ steps.gradle.outputs.build-scan-url }}
