How to include "org.openhab.core.io.transport.mqtt" dependency lib in a new custom binding

Hi All,

i have a self-developed binding that requires smarthome.io.transport.mqtt. When i try to run debug through demo-app, i am getting dependency issue for this self-developed binding of not including smarthome.io.transport.mqtt or openhabe.io.transport.mqtt. I am new to this 2.5 Eclipse IDE, how do i do it? In 2.4, i can just “tick” .io.transport.mqtt in run setting, but with demo-app, i am totally lost how to load additional lib to about li reference dependency problem . Cheers
