###If you are planning to copy the impl and REST jars directly to the deploy directly, then do a

feature:repo-add cxf 3.1.4
feature:install cxf

in your karaf shell.

###If you are planning to use the feature.xml in your .kar project, use

feature:repo-add <<<PATH TO YOUR FEATURE.XML>>>/feature.xml
feature:install karafcxf

###Verify your installation using

karaf@root()> list | grep karafcxf
162 | Active |  80 | 1.0.0.SNAPSHOT | karafcxf.service.impl
163 | Active |  80 | 1.0.0.SNAPSHOT | karafcxf.rest
