Zig Maven plugin

This plugin allows you to execute zig build to build JNI code of your java project as a part of maven build to cross compile it for different platforms making JNI great again ;).

Check https://ziglang.org to learn about zig. The most exciting things are:

• it can compile C code
• it can cross compile C code for different targets (linux/win/osx/...)

Check jnidemo project for quick example how to do it

How it works

It downloads zig runtime for your platform and caches it in ~/.zigcache directory. Also, it downloads missing JNIheaders necessary for cross compilation. As of now headers are provided for windows, linux, osx

It uses build.zig file (must be next to your pom.xml) and runs zig build according to parameters configured for the plugin. Check the sample pom.xml copied from jnidemo project:

One last thing

You can code JNI in zig! Happy hacking :)
