Pull request overview
This pull request restores compatibility with workflows that expect GRAALVM_HOME to be set (notably when migrating from graalvm/setup-graalvm) by exporting GRAALVM_HOME whenever a GraalVM distribution is installed via actions/setup-java.
Changes:
- Export GRAALVM_HOME (set to the same path as JAVA_HOME) for GraalVM distributions by overriding setJavaDefault.
- Add unit coverage to verify GRAALVM_HOME is exported for both Oracle GraalVM and GraalVM Community.
- Update the checked-in compiled action bundle (dist/setup/index.js).
| File | Description |
|---|---|
| src/distributions/graalvm/installer.ts | Override setJavaDefault to export GRAALVM_HOME alongside the existing JAVA_HOME behavior. |
| tests/distributors/graalvm-installer.test.ts | Adds tests asserting GRAALVM_HOME is exported for Oracle GraalVM and GraalVM Community installers. |
| dist/setup/index.js | Updates the bundled distribution to include the new GRAALVM_HOME export logic. |
