Develop a new app on OpenDaylight Nitrogen SR1, but the xxxProvider.java isn't be inited

Question

I want build a App based on Nitrogen SR1 version, my steps are:

1. Build a maven project with command: mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeRepository=http://nexus.opendaylight.org/content/repositories/opendaylight.release -DarchetypeCatalog=remote -DarchetypeVersion=1.4.1 enter image description here

2. groupId: org.opendaylight.hni artifactId: hni enter image description here

3. After build success ,I build this “hni app” with command: Mvn clean install -DskipTests enter image description here

4. After build success. I start this “hni app”’s Karaf, and feature
   install hni. Then I went to see log , my two features: Features-hni & odl-hni-api They are both installed. enter image description here enter image description here

5. But there should be “HniProvider Session Initiated” in this log file. Cuz my code: HniProvider.init() should print these words.
   However,they aren’t be printed in log file. enter image description here

So I want ask Why? When I build a app based on Carbon version, I follow these steps ,too. But the “HniProvider Session Initiated” is be printed in log in Carbon version.

What are the diffences between the Carbon and Nitrogen,when building apps ??? Thx very much .

The problem is that only the generated odl-X-api feature (odl-hni-api in your case) is installed - so the implementation code that logs that output isn't installed. This is because the features-X pom only lists the odl-X-api feature as a dependency - it needs to also list the odl-X feature which has the implementation bundle, and the odl-X-cli and odl-X-rest features (if you want those). This is fixed in https://git.opendaylight.org/gerrit/#/c/66545/.
