GitHub Action for GraalVM

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

Key Features

This action:

• supports GraalVM Community Edition (CE) releases, dev builds, GraalVM Enterprise Edition (EE) releases (set gds-token) 22.1.0 and later, and Mandrel (see options)
• has built-in support for GraalVM components and the GraalVM Updater
• exports a $GRAALVM_HOME environment variable
• adds $GRAALVM_HOME/bin to the $PATH environment variable
  (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 amd64 and aarch64 (selected automatically, aarch64 requires a self-hosted runner)
• sets up Windows environments with build tools using vcvarsall.bat
• supports dependency caching for Apache Maven, Gradle, and sbt (see cache option)

Basic GraalVM Enterprise Edition Template

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.

cache	''	Name of the build platform to cache dependencies. It can 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.

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