As a part of web UI customization, we had built the Web UI jar files from the web UI repo
(https://github.com/openhab/openhab-webui).
The jar files have been copied to the path “/usr/share/openhab2/addons”, But the updated addons are not visible in the “paperUI->addon->userinterface”.
If anybody has a solution to this issue, please share
Karaf features are used to install add-ons in the UI. This information is not part of the bundles (JARs) themselves. Using Karaf features it is also possible to install multiple bundles or define dependencies between features so they are automatically installed when needed.
