Looking around JVM use aarch64 for ARMv8 and as per plugin documentation ARMv8 is not supported, neither by NodeJS 14 distribution.

Recent SUSE 12 version supports aarch64. I do not know if aarch64 means arm64. I do not have a Raspberry 3+ for test.

nfalcoThank you for looking into this!

Looking around JVM use aarch64 for ARMv8 and as per plugin documentation ARMv8 is not supported

I guess my issue is a feature request then.

ARMv8 is the same as aarch64 in practical terms I believe (can confirm that my R. Pi 4 declares itself as aarch64 and runs NodeJS' ARM64 builds just fine.

neither by NodeJS 14 distribution.

See above regarding aarch64 and ARM64 being the same (in practical terms)

Recent SUSE 12 version supports aarch64.

Ubuntu also, if that helps.

I do not know if aarch64 means arm64.

See above. Basically: yes, it does.

I do not have a Raspberry 3+ for test.

Understandable. What I can offer in terms of help is the testing of the plugin on my Raspberry Pi 3 and 4 if someone were to implement the feature being requested here. Of course I do not know how feasible that is without the person writing the code having access to an R. Pi. Maybe they can use other machines, like something provisioned in the cloud that also has an ARM64 arch, just guessing here.

I did the changes, you can build the plugin (mvn clean package) and install on your side. If it's ok I will release.

1. NodeJS Plugin 1.3.10
2. Jenkins 2.277
3. NodeJS 14.15.3

I prepared a Java Main that I need you run on the machines on which you would enable nodejs to undertand how JVM recognize those CPU and the O.S.

public class Main {
    public static void main(String[] args) {
        System.out.println(System.getProperty("os.arch"));
        System.out.println(System.getProperty("os.name"));
    }
}

nfalco Cheers mate. Thanks for your prompt response. Actually, I ran my project on an M1 chip MacBook Pro in a jenkins4eval/jenkins container, which inside the docker preview version. I have two JRE version on my laptop, one is "Zulu 13.35.1025 [13.0.5.1]", another is "JRE "[15.0.1]". So, I got the two different results of that code: "aarch64, Mac OS X" and "x86_64, Mac OS X". I believe the Zulu one is my primary JRE environment.

In that case which nodejs installation do you expect?

This https://nodejs.org/dist/v14.15.4/node-v14.15.4-darwin-x64.tar.gz or this https://nodejs.org/dist/v14.15.4/node-v14.15.4-linux-arm64.tar.xz

I see some open issue in the nodejs at github repo about "Apple Silicon" (https://github.com/nodejs/build/issues/2474)

EDIT Reading around seems that only v15 is able to run nativly on M1 Mac but a bit instable for some packages/connector.

Since this issue is about arm64 on embedded system I will close. Reopen a new feature issue to request arm64 on M1 Mac

My fault there is an issue in the check

Fantastic! Really appreciate it! 

Great job!
