People like me who are migrating from `graalvm/setup-graalvm@v1` will have builds that expect this env variable to be set.\n\nI believe the same issue will be present for Oracle GraalVM, but I have not verified.\n\n**Task version:**\n\nv5.6.0\n\n**Platform:**\n- [x] Ubuntu\n- [x] macOS\n- [ ] Windows\n\n**Runner type:**\n- [x] Hosted\n- [ ] Self-hosted\n\n**Repro steps:**  \n\nTun a build that requires `GRAALVM_HOME` to be set.\n\n**Expected behavior:**\n\nThe build to succeed, the same as it did when using `graalvm/setup-graalvm@v1`.\n\n**Actual behavior:**\n\nThe build fails (in my case by an invalid path to the `native-image` binary because my build is using `GRAALVM_HOME` to find it.)\n\n**Workaround:**\n\nUse:\n\n```\n  - name: Set up Java (GraalVM)\n    uses: actions/setup-java@v5\n    with:\n      distribution: ${{ matrix.distribution }}\n      java-version: ${{ matrix.java-version }}\n      cache: 'gradle'\n  # `actions/setup-java` doesn't set `GRAALVM_HOME` so we'll do it explicitly.\n  - name: Set GRAALVM_HOME\n    run: echo \"GRAALVM_HOME=$JAVA_HOME\" >> \"$GITHUB_ENV\"\n```","author":{"url":"https://github.com/msgilligan","@type":"Person","name":"msgilligan"},"datePublished":"2026-07-20T22:15:44Z","url":"https://github.com/actions/setup-java/issues/1139"}
