Maven requires $JAVA_HOME to be set correctly e.g.

cd ~
cat .bash_profile
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home

Running the driver with Houm.io

cd ~
git clone https://github.com/houmio/houmio-driver-knx

Add HOUMIO_KNX_IP="aaa.bbb.ccc.ddd" to ~/houmio.conf environment.

Add HOUMIO_NETWORK_INTERFACE=putyourinterfacehere to ~/houmio.conf environment, if the host has multiple network interfaces.

sudo service supervisor restart

Building and running from the command line

Set env variable HOUMIO_KNX_IP to point to your KNX IP gateway.

Set env variable HOUMIO_NETWORK_INTERFACE if the host has multiple network interfaces.

Then:

mvn clean install
java -jar target/houmio-driver-knx-0.0.1-jar-with-dependencies.jar
