Hi, dear Jean-Baptiste Onofré. I am talking about this repository. It does not work.
I've checked out https://github.com/jbonofre/karaf/tree/DEV_GUIDE $ git clone -b DEV_GUIDE https://github.com/jbonofre/karaf/tree/DEV_GUIDE karaf_dev_guide Build it with maven: $ mvn -DskipTests -Pfastinstall clean install Went to the distribution/assembly: $ cd assemblies/apache-karaf/target/assembly/ and started Karaf from here: $ JAVA_HOME=/opt/jdk ./bin/karaf debug Listening for transport dt_socket at address: 5005 __ __ ____ / //_/____ __________ _/ __/ / ,< / __ `/ ___/ __ `/ /_ / /| |/ /_/ / / / /_/ / __/ /_/ |_|\__,_/_/ \__,_/_/ Apache Karaf (4.2.1-SNAPSHOT) >From here, first and only thing I do is: karaf@root()> feature:repo-add mvn:org.apache.karaf.examples/karaf-jpa-example-features/4.2.1-SNAPSHOT/xml karaf@root()> feature:install karaf-jpa-example-datasource karaf@root()> feature:install karaf-jpa-example-provider org.apache.felix.resolver.reason.ReasonException: Unable to resolve root: missing requirement [root] osgi.identity;

What am I doing wrong - are there any pre-requirements ?
