Installing MQTT binding in OpenHAB 2.0 break HUE binding

I Installed MQTT Binding, and immediately after the installation, HUE binding stops working. The OpenHAB log shows the following error while initializing my HUE thing:

“java.lang.NoSuchMethodError: org.eclipse.smarthome.config.core.Configuration.get”

No mqtt specific errors are shown.

Even after uninstalling the MQTT Binding and restarting OpenHAB, the error persists. I uninstalled and re-installed HUE Binding but the error remains. I needed to recover from a backup.

In Paper UI, the Extensions option in Menu is not shown.

My setup: OpenHAB 2.0 running on Raspberry pi3, ubuntu-mate 16.04

Any ideas?

There was a small change in the ESH API, which unfortunately now requires bindings to be recompiled in order to run on latest distro builds, see https://github.com/eclipse/smarthome/issues/1446.
So please compile the MQTT binding again and the new binary should work as expected.

I have just released a new stable ESH build which contains https://github.com/eclipse/smarthome/pull/1449 - so on the latest distro, “old” bindings should again work without the need to recompile them!
