it is better to install from repository - it will download all required library automatically.
for this, execute in karaf console
install https://openhab.jfrog.io/openhab/libs-pullrequest-local/org/openhab/addons/bundles/org.openhab.io.homekit/2.5.7-SNAPSHOT/org.openhab.io.homekit-2.5.7-SNAPSHOT.jar
or if binding already there
update <id of homekit binding> https://openhab.jfrog.io/openhab/libs-pullrequest-local/org/openhab/addons/bundles/org.openhab.io.homekit/2.5.7-SNAPSHOT/org.openhab.io.homekit-2.5.7-SNAPSHOT.jar
it looks like this.
