I try to follow the new guide to setup my openhab dev environment (openhab 3.x):
When I Follow instructions in “Running Add-ons” to add knx addon to pom.xml.
I can start openhab, and everything is working ok.
But when I try to Follow instructions in " Modifying and Debugging Add-ons".
Wehn i start openhab, I get the following errors.
org.osgi.framework.BundleException: Could not resolve module: org.openhab.binding.knx 
Unresolved requirement: Import-Package: gnu.io; version="[3.12.0,6.0.0)"
I try many thing in the app.bdrun window, like trying to resolve dependencies, adding other binding like serial.transport, but this doesn’t resolve the error.
Can some one point me to a way to fix this.
