Support Mac-arm64 target

It would be nice if Jansi worked on the M1 so that colors work in Maven.

[mattsalt]

Colours worked on maven 3.8.1 using Jansi 1.17.1 but not in maven 3.8.2 using Jansi 2.3.4.

Confirmed using the example snippet in the README.
System.out.println( ansi().eraseScreen().fg(RED).a("Hello").fg(GREEN).a(" World").reset() );

1.17.1

2.3.4

Stopped working in 2.1.1

[mattsalt]

Looks like there was no native method in 2.0.1 either but the exception was caught and defaulted to RESET_ANSI_AT_CLOSE

[electrum]

I found that colors still work with -Dstyle.color=always.

[mattsalt]

That's handy. alias mvn="mvn -Dstyle.color=always it is then.

[davsclaus]

Anyone tracked down why colors stopped workin in 2.1.1?

I dont have colours either in mvn 3.8.2

@gnodet btw when you use maven 3.8.3, and mvnd 0.6.0 then you have this on aarch64 mac apple m1

mvnd --version

So if we can get jansi to support aarch64 and into a new release then mvnd could use that and get this working ;)

[gnodet]

Could you try the #222 PR and see if the library is valid ?
Simply building jansi and replacing the binary in mvnd / mvn installation should do the trick...
I can't really test it with my x64 Mac ;-)

[davsclaus]

@gnodet not sure if I should build it in another way, this is what I did, see the gist

And this is with your PR merged.

@davsclaus , this looks like maven is shading the being-built version of jansi. Could you comment the exec-maven-plugin plugin from the pom so that you can actually build jansi ?

Then simply run the following command and give the output ?

java -jar target/jansi-2.3.5-SNAPSHOT.jar

[davsclaus]

Thanks, here is the output
