Hi I am using the latest version of Niagara 3.8, to build modules on my local machine, I cloned the nhaystack ax branch and tried to build it, but it throws  a couple of errors that make me thing I need to use a different version of Niagara AX, just not sure which one would be the optimal one, below is the build console output.
Any guidance is greatly appreciated, thanks.

Hi Victor,

That looks like an issue with trying to compile the module using a J2ME directive but the module uses Java SE code and libraries.

I've contacted you offline about this and will follow up with you shortly.

Cheers, Richard

thanks Richard.
