Error when trying to install a feature in Karaf

I have installed and run Karaf, and I have also installed many features. But when I try this :

feature:install odl-openflowplugin-app-lldp-speaker-li

I get the following error :

Error executing command: Can't install feature odl-openflowplugin-app-lldp-speaker-li/0.0.0:
null

The same is happening with this :

feature:install odl-openflowplugin-li

and has happened previously with some other features too. What is going wrong?

Solution

OpenDaylight maintains its own repositories outside of Maven Central, which means maven (and therefore pax-url used by Karaf feature service) cannot resolve OpenDaylight artifacts by default.

Try to add the opendaylight maven repo in your ~/.m2/settings.xml file: see the opendaylight official docs.

After this, you should also double check to install the right feature repo in Karaf with the feature:repo-add command, for example:

karaf@root()> feature:repo-add \
    mvn:org.opendaylight.controller/features-mdsal/1.3.4-Beryllium-SR4/xml/features

Hope this helps...
