Why can't my project find an artifact when I've specified it in pom-xml?

I'm working in a ODL project and at this moment I'm in the first steps. I want to import the PacketProcessingListener and PacketReceived but I'm having an error when I use mvn clean install.

My project uses the Carbon version of ODL so to create it I used this command:

mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller
-DarchetypeCatalog=remote -DarchetypeVersion=1.3.0-Carbon

I have a java file ( in my impl/src/main/java/org/opendaylight/packetCounter/impl directory where I've imported these two classes:

import org.opendaylight.yang.gen.v1.urn.opendaylight.packet.service.rev130709.PacketProcessingListener;
import org.opendaylight.yang.gen.v1.urn.opendaylight.packet.service.rev130709.PacketReceived;

I've read that I have to add the dependency of these two classes into my pom.xml so I've used this (according to the result of the search on this website ):


(BTW I'm not sure if that version is the appropriate for this case).

Finally, when I use the mvn clean install command I get this error:

I'd appreciate some help to solve this problem.

Thank you.

Hi Daniel,

You are using version 1.3.0-Carbon for the archetype generation, which corresponds to the original Carbon release. The corresponding model-flow-version would be 0.4.0-Carbon. The last digit in the version, the patch-level, indicates the Service Release. For Carbon, only SR1 was released, and SR2 is being prepared now. If you click in the search results on the 0.4.2-Carbon artifact you found you will see that it belongs to an "autorelease" repository. While public, it's best to use only "public" repositories.

So I would recommend using Carbon SR1 artifacts for now, 1.3.1-Carbon for the archetype generation and 0.4.1-Carbon for your dependency. For some reason the search results also show 0.4.1 as autorelease repo, but if I check Nexus, it's actually available in the release repo:

Alternatively, while developing you can use the original version too, 0.4.0-Carbon to match your archetype, and upgrade later.

Thanks Lori. I've used the 0.4.1-Carbon version for the dependecy and it works! And thank you for the explanation. I think I can understand now the meaning of these set of numbers haha.
