• Found at Fixes HotSpot JDK 22 CI failure due to GR-54293 apache/shardingsphere#32267 .
• On GraalVM CE For JDK 22.0.1, using Espresso is very intuitive.

</dependencies>
    <dependency>
        <groupId>org.graalvm.polyglot</groupId>
        <artifactId>polyglot</artifactId>
        <version>24.0.1</version>

• But starting with GraalVM CE For JDK 22.0.2 including [GR-54293] Allow multiple espresso runtime resources to coexist. #9020, you also need a espresso-runtime-<RuntimeResourceId> related Maven dependency as RuntimeResourceId. This sounds similar to,

</dependencies>
    <dependency>
        <groupId>org.graalvm.polyglot</groupId>
        <artifactId>polyglot</artifactId>
        <version>24.0.2</version>

• Note that https://central.sonatype.com/artifact/org.graalvm.espresso/espresso-runtime-resources-linux-amd64/24.0.2 has changed LICENSE. org.graalvm.espresso:espresso-runtime-resources-linux-amd64:24.0.1 is GNU General Public License, version 2, but org.graalvm.espresso:espresso-runtime-resources-linux-amd64:24.0.2 is GraalVM Free Terms and Conditions (GFTC) including License for Early Adopter Versions. But it looks like the only espresso-runtime-<RuntimeResourceId> is org.graalvm.espresso:espresso-runtime-resources-linux-amd64. I don't see a description of the LICENSE changes in the CHANGELOG , so I'm assuming I'm actually missing some documentation?

Describe the solution you'd like.
A clear and concise description of what you want to happen.

• Provide an espresso-runtime-<RuntimeResourceId> with UPL or GPL as the LICENSE.

Thanks for reaching out about this @linghengqian.

Note that you can use org.graalvm.polyglot:java instead of org.graalvm.polyglot:java-community, that would automatically bring in the necessary dependencies.
It is licenced as GFTC so it's free even for production use. See the FAQ.

For GPL espresso-runtime-resource bits based on OpenJDK21 you'd need:

• A standard build (on all platforms)
• A "sulong"/"llvm" build (on linux and darwin amd64 at the moment)

Maybe the GraalVM backport maintainers could publish those in the future? /cc @zakkak

There should be nothing special about the standard build.
For the llvm build, you'll need a Sulong toolchain and build the JDK with that.
Then you can point ESPRESSO_JAVA_HOME to the standard build and ESPRESSO_LLVM_JAVA_HOME to the llvm build.
With that you should be able to build ESPRESSO_RUNTIME_RESOURCES.
To get all platforms merged, you can use mx archive-pd-layouts/mx restore-pd-layouts and mx --multi-platform-layout-directories=... build.
I can provide further details on how to build if necessary.

• Thanks for the clarification, I don't think it's necessary to discuss how to do a standard build vs a sulong/llvm build in the current issue, I'm assuming there's actually a document for this.
• Just waiting for @zakkak to confirm if this will make it back to https://github.com/graalvm/graalvm-for-jdk21-community-backports .
