Thanks for contacting us!
I appreciate all the information provided, I have found this guide in order to use Mraa on the Intel Edison with Maven and Eclipse, please take a look at this link: http://appiot-docs.azurewebsites.net/?p=9331, and let me know if that information helps or if you have any other question.
It seems to be a purely packaging problem with maven I suppose. Exporting as executable jar with Eclipse (which works) seems to include all dependencies whereas with maven it doesn't.
I'm resting my case here since it has nothing to do with the board itself.
Thanks for the tip Yermi
