Fixed an issue with jinput native binary on Apple Silicon

Fixes the following jinput issue: jinput/jinput#325

Thanks. What platforms and matlab versions did you test the output with?

[bgrochowski]

Tested with macOS 15.4.1 on M1 Pro and Matlab R2025a

Just tested on Windows 11 x64 + Matlab R2025a - the previous commit resulted in Java runtime errors. Namely, the newer Jinput version 2.0.10 (which added macOS Apple Silicon support) was compiled with release flag for JRE version 17. Update in the newest commit solves the issue by recompiling Jinput during mvn package for JRE version 8. Now it is tested working on both macOS 15.4.1 and Windows 11.

I hate when that happens. The ecosystem has largely moved beyond Java 8, but we'll need to support it for MATLAB indefinitely.

Do the native sources need to get compiled as well? If so, does CI need to setup specific compilers?

[bgrochowski]

The native sources remain precompiled, only the Java classes need to be rebuilt (both "core" and platform-specific plugins).

I haven't forgotten about this, but I'd like to run my own tests on different platforms and probably won't be able to get to this until next week. Sorry for the delay.

[bgrochowski]

No problem, thank you for the project and for verifying the changes! Please let me know if I can assist you with something.

change to <outputDirectory>matlab/lib/</outputDirectory> without the leading slash

When running mvn clean package on Windows 11 I get a build error

after fixing that I get a class not found error on the JInput classes when running kb = HebiKeyboard

I don't have a physical joystick here at the moment, so I can't test that part.

[bgrochowski]

Apologies for the late response. The newest commit solves this problem; apparently, the newer version of jinput requires including awt-plugin dependency explicitly in the pom.xml file. Now, both HebiKeyboard and HebiJoystick appear to work correctly. Tested on Windows 11 x64 + Matlab R2025a, I will run another test on macOS this week.
