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 .
