Where to place extension .JAR file?

I created an extension for OH2 in eclipse and built it using mvn install.
Where do I place the JAR file so that is seen by the openHAB 2 runtime?

You can put it in the /addons folder.

You might also want to then look in the Karaf console - use the ‘list’ command to make sure it loaded and see if it’s actually started.

Great, it worked!

Note:
For those running openHAB2 in a docker container do the following:
$ docker cp org.openhab.binding.mybinding-2.0.0-SNAPSHOT.jar <container-id>:/openhab/addons
$ docker restart <container-id>
