this happens (i think) because both the Mac and unix modules are compiled on Mac with the yad2xx-master/pom.xml code. both modules use the net.sf.yad2xx:libFTDIInterface:1.0 and mvn does not like having a module twice in the project hierarchy/tree.

the solution is to specify the <name> tag in addition to the <family> tag in the module info. i have confirmed that this fixes the compile problem on mac and i am submitting a pull request on github for you to check out.</family></name>

Hi,
which version of macOS are you running?

Today I upgraded to Mojave. I then synched my local git repo with GitHub (was already up to date).

I tried running mvn and got a weird error, need to run 'xcode-select --install'. Once that had run ok I executed 'mvn clean install', ran just fine.

Hi Stephen, i am on 10.11.6 El Capitan. That OS definitely activates the unix module in the pom.xml in my hands. i dont think there is much need for a cross-compile, so restricting the linux build in the <family>unix</family> to <name>Linux</name> will do no harm but solves the problem I ran into. P.S. Yes, the Xcode CLI is used in a lot of the installs like Macports and others. Be well,
