OpenHAB release from Eclipse IDE vs Openhabian image


I tried to use Telegram binding with a predefined image for Raspberry and it works.
So now I would like to modify Telegram binding and test it.
I installed Eclipse IDE using developer guide and launch it using “openHAB_Runtime.launch”, but I did not see the same Paper UI as in the predefined image. I can not install bindings and I do not have same functional as in the Openhabian image.
What I did wrong and how can I manage it?

Best regards,
