GitHub Action for GraalVM build-test

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

Key Features

This action:

  • supports Oracle GraalVM releases, EA builds, GraalVM Community Edition (CE) releases, dev builds, GraalVM Enterprise Edition (EE) releases (set gds-token) 22.1.0 and later, Mandrel, and Liberica Native Image Kit (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

Template for GraalVM Enterprise Edition

Prerequisites

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

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

The 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
    # ...

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).
