No native library found for os.name=Linux, os.arch=aarch64

[lanmaoxinqing]

The os.arch system variable may be aarch64 in some linux arm64 machines like below and OSInfo.java in native module doesn't recognize it.

$ uname -a
Linux xxx xxx.aarch64 #1 SMP Fri Aug 9 04:09:13 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux

I will submit a PR for this later if it's necessary to compatible with this situation.

It seems that org.fusesource.jansi:jansi:2.3.2 which we dependent on also uses OSInfo.java and has the same question, So this PR can not cannot actually work until we release a newer jansi version with aarch64 support.

    public static String getArchName() {
        String osArch = System.getProperty("os.arch");
        // For Android
        if (isAndroid()) {
            return "android-arm";
        }

        if (osArch.startsWith("arm")) {    //  <-- linux arch named `aarch64` can not go into this
            osArch = resolveArmArchType();
        } else {
            String lc = osArch.toLowerCase(Locale.US);
            if (archMapping.containsKey(lc))
                return archMapping.get(lc);
        }
        return translateArchNameToFolderName(osArch);
    }

I was able to workaround the issue by doing:

cp -r ./native/src/main/resources/org/mvndaemon/mvnd/nativ/Linux/arm64 ./native/src/main/resources/org/mvndaemon/mvnd/nativ/Linux/aarch64

For some reason it tries to find native-image in my JDK 11 installation. I had to export JAVA_HOME to point to GRAALVM_HOME to overcome this one.

Update: Apologies! This is mentioned in the README!

As mentioned by @lanmaoxinqing the last problem is in Jansi library:

Fixed by @lanmaoxinqing with fusesource/jansi#219

[gnodet]

I'm working on jansi these days. There's one issue remaining which is Apple/M1 support which I'd like to get in before releasing it.

[martin-g]

I was able to build mvnd locally but the README does not explain how to package it properly to make use of it.
I've copied the binary to $PATH:

cp client/target/mvnd ~/bin/

but then trying to use it fails with:

Exception in thread "main" java.lang.IllegalStateException: Could not get value for Environment.MVND_HOME from any of the following sources: value: mvnd.home, path relative to the mvnd executable, system property mvnd.home, environment variable MVND_HOME, property mvnd.home in /home/ubuntu/devel/mvnd/.mvn/mvnd.properties, property mvnd.home in /home/ubuntu/.m2/mvnd.properties

I need to copy some more files and folders next to it to make it look like the archives in GitHub releases.

[gnodet]

@martin-g I've added some infos at https://github.com/mvndaemon/mvnd#install-mvnd, let me know if this is sufficient.

[martin-g]

Confirmed! Everything works now!
Thank you, @lanmaoxinqing & @gnodet !
