This seems to be expected behavior, as Kai wrote in the announcement. > [@Distributing bindings through the IoT Marketplace](https://community.openhab.org/t/distributing-bindings-through-the-iot-marketplace/24491/1): > > Note 2: The jars are installed in the OSGi cache - which means that they are lost upon an openHAB distro upgrade (which cleans the cache) - you will have to manually re-install then from the marketplace. As the main use case for the start will be for testing pre-releases, I think this is acceptable. For the future, I also plan an improved mechanism, which would download the jars to the addons folder (or something similar), so that they are kept over an upgrade as well. --- _[View the full topic](https://community.openhab.org/t/binding-uninstalls-when-new-nightly-is-installed/27997)._
