onos-Backend error

[whulzp]

Hi all,
when I enter the onos-backend project directory and compile the code''mvn clean install'',there is an error：
Failed to execute goal org.onosproject:onos-maven-plugin:1.10:app (app) on project onos-app-backend: Unable to stage artifact mvn:org.onosproject/onos-protocols-openflow-ctl/1.7.0: File /root/.m2/repository/org/onosproject/onos-protocols-openflow-ctl/1.7.0/onos-protocols-openflow-ctl-1.7.0.jar does not exist

My onos is 1.7.0,and it is good running.
any idea?
Thank you everyone

I suggest you to move to ONOS 1.7.1

This error is strange, by default all the downloads of Backend dependencies from Maven repository are on ONOS version 1.7.1. I endorse the solution proposed by @doriguzzi, since the ONOS backend is tested for ONOS 1.7.1. Moreover, you are running in the root and I don't think that Maven likes it. Check also that your machine can reach the Maven online repo.

I tried to buck build onos1.7.1,but failed ,would mind give me a course about "how to buck the onos" ,or can you give the onos that you haved buck build.I am a novice ,hope you don't mind.
