GitHub Action for GraalVM

This GitHub action sets up Oracle GraalVM, GraalVM Community Edition (CE), Enterprise Edition (EE), or Mandrel, as well as Native Image and GraalVM components such as Truffle languages.

Key Features

This action:

supports Oracle GraalVM releases, GraalVM Community Edition (CE) releases, dev builds, GraalVM Enterprise Edition (EE) releases (set gds-token) 22.1.0 and later, and Mandrel (see Options)
exports a $GRAALVM_HOME environment variable
adds $GRAALVM_HOME/bin to the $PATH environment variable
(Native Image, Truffle languages, and tools can be invoked directly)
sets $JAVA_HOME to $GRAALVM_HOME by default
(can be disabled via set-java-home: 'false', see Options)
supports x64 and aarch64 (selected automatically, aarch64 requires a self-hosted runner)
supports dependency caching for Apache Maven, Gradle, and sbt (see cache option)
sets up Windows environments with build tools using vcvarsall.bat
has built-in support for GraalVM components and the GraalVM Updater

Migrating from GraalVM 22.3 or Earlier to the New GraalVM for JDK 17 and Later

The new GraalVM for JDK 17 and JDK 20 release aligns the GraalVM version scheme with OpenJDK. As a result, this action no longer requires the version option to select a specific GraalVM version. At the same time, it introduces a new distribution option to select a specific GraalVM distribution (graalvm, graalvm-community, or mandrel). Therefore, to migrate your workflow to use the latest GraalVM release, replace the version with the distribution option in the workflow yml config, for example:

# ...
- uses: graalvm/setup-graalvm@v1
  with:
    java-version: '17'
    version: '22.3.2' # Old 'version' option for the GraalVM version
    # ...

can be replaced with:

# ...
- uses: graalvm/setup-graalvm@v1
  with:
    java-version: '17.0.7' # for a specific JDK 17; or '17' for the latest JDK 17
    distribution: 'graalvm' # New 'distribution' option
    # ...

Template for GraalVM Enterprise Edition

Prerequisites

Download the version of GraalVM Enterprise Edition (EE) you want to run on GitHub Actions.
Use the GraalVM Updater to install the GraalVM components you need on GitHub Actions and accept the corresponding licenses.
Run $GRAALVM_HOME/bin/gu --show-ee-token to display your token for the GraalVM Download Service.
Store this token as a GitHub Action secret. For this template, we use the name GDS_TOKEN.

Options

Name	Default	Description
`java-version` (required)	n/a	`'17.0.7'` or `'20.0.1'` for a specific Java version, `'dev'` for a dev build with the latest Java version available. (`'8'`, `'11'`, `'16'`, `'19'` are supported for older GraalVM releases.)
`distribution`	`''`	GraalVM distribution (`graalvm` for Oracle GraalVM, `graalvm-community` for GraalVM Community Edition, `mandrel` for Mandrel).
`github-token`	`'${{ github.token }}'`	Token for communication with the GitHub API. Please set this to `${{ secrets.GITHUB_TOKEN }}` (see templates) to allow the action to authenticate with the GitHub API, which helps reduce rate-limiting issues.
`set-java-home`	`'true'`	If set to `'true'`, instructs the action to set `$JAVA_HOME` to the path of the GraalVM installation. Overrides any previous action or command that sets `$JAVA_HOME`.
`cache`	`''`	Name of the build platform to cache dependencies. Turned off by default (`''`). It can also be `'maven'`, `'gradle'`, or `'sbt'` and works the same way as described in actions/setup-java.
`check-for-updates`	`'true'`	Annotate jobs with update notifications, for example when a new GraalVM release is available.
`native-image-musl`	`'false'`	If set to `'true'`, sets up musl to build static binaries with GraalVM Native Image (Linux only). Example usage (be sure to replace `uses: ./` with `uses: graalvm/setup-graalvm@v1`).
`native-image-job-reports` *)	`'false'`	If set to `'true'`, post a job summary containing a Native Image build report.
`native-image-pr-reports` *)	`'false'`	If set to `'true'`, post a comment containing a Native Image build report on pull requests. Requires `write` permissions for the `pull-requests` scope.
`components`	`''`	Comma-separated list of GraalVM components (e.g., `native-image` or `ruby,nodejs`) that will be installed by the GraalVM Updater.
`version`	`''`	`X.Y.Z` (e.g., `22.3.0`) for a specific GraalVM release up to `22.3.2` `mandrel-X.Y.Z` (e.g., `mandrel-21.3.0.0-Final`) for a specific Mandrel release, `mandrel-latest` for latest Mandrel stable release.
`gds-token`	`''`	Download token for the GraalVM Download Service. If a non-empty token is provided, the action will set up GraalVM Enterprise Edition (see GraalVM EE template).

*) Make sure that Native Image is used only once per build job. Otherwise, the report is only generated for the last Native Image build.
