Use of a wrapper in a non-standard directory is uncommon, and is effectively handled by referencing the `gradlew` script as the `gradle-executable`.
Execute Gradle commands in GitHub Actions workflows
This GitHub Action can be used to run arbitrary Gradle commands on any platform supported by GitHub Actions.
You might also be interested by the related Gradle 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.
# .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@v2
- uses: actions/setup-java@v1
with:
java-version: 11
- uses: eskatos/gradle-command-action@v1
with:
arguments: build
Gradle arguments
The arguments
input can used to pass arbitrary arguments to the gradle
command line.
Here are some valid examples:
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:
- uses: eskatos/gradle-command-action@v1
env:
CI: true
Run a build from a different directory
- uses: eskatos/gradle-command-action@v1
with:
build-root-directory: some/subdirectory
Use a specific gradle
executable
- uses: eskatos/gradle-command-action@v1
with:
gradle-executable: path/to/gradle
Use a Gradle wrapper from a different directory
- uses: eskatos/gradle-command-action@v1
with:
gradle-executable: path/to/gradlew
NOTE: The wrapper-directory
input has been deprecated. Use gradle-executable
instead.
Setup and use a declared Gradle version
- uses: eskatos/gradle-command-action@v1
with:
gradle-version: 6.5
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 |
rc |
The current release candidate if any, otherwise fallback to current |
nightly |
The latest nightly, fails if none. |
release-nightly |
The latest 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:
# .github/workflows/test-gradle-rc.yml
name: Test latest Gradle RC
on:
schedule:
- cron: 0 0 * * * # daily
jobs:
gradle-rc:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- 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
Caching
This action provides 3 levels of caching to help speed up your GitHub Actions:
distributions
caches any downloaded Gradle zips, including any downloaded wrapper versions, saving time downloading Gradle distributions ;dependencies
caches the dependencies, saving time downloading dependencies ;configuration
caches the build configuration, 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:
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.
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:
**/*.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:
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 you can make the dependencies cache more precise with the following configuration:
dependencies-cache-enabled: true
dependencies-cache-key: gradle/dependency-locks/**
dependencies-cache-exact: true
Build scans
If your build publishes a build scan 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:
# .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@v2
- uses: actions/setup-java@v1
with:
java-version: 11
- uses: eskatos/gradle-command-action@v1
with:
arguments: build
id: gradle
- name: "Comment build scan url"
uses: actions/github-script@v3
if: github.event_name == 'pull_request' && failure()
with:
github-token: ${{secrets.GITHUB_TOKEN}}
script: |
github.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 }}'
})
