I am trying to set up [Sonar Gerrit - Jenkins Plugin](https://wiki.jenkins-ci.org/display/JENKINS/Sonar+Gerrit#SonarGerrit-Gerrit) on a Jenkins job.

**Context** 

1. A Jenkins job is launched when a patch set is created to Gerrit
2. Source are pulled with git, cppcheck analysis is launched and a sonar analysis is launched on preview mode.
3. Post-Build action "Post SonarQube issues as Gerrit comments" is launched.

Here are the Jenkins analysis logs for the third point.

```
Getting Sonar Report from: [XX].sonar\sonar-report.json
Report has loaded and contains 2950 issues
Connected to Gerrit: server name: Gerrit. Change Number: 297, PatchSetNumber: 1
Unable to post review: Request failed.
Build step 'Post SonarQube issues as Gerrit comments' marked build as failure
Finished: FAILURE

```

A comment is added to Gerrit (meaning the communication works)

> 
> Build Failed
>  http:jenkins.com/job/project/118/ : FAILURE
> 
> 
> 

I am not able to understand where the configuration is not right. Do you know this issue ? 

On Gerrit `httpd_log` file I have following lines when I launched a new Jenkins job.

> 
> IP **- -** [26/oct./2016:14:30:08 +0200] "POST /a/changes/REF/revisions/REF/review HTTP/1.1" 401 12 - "Apache-HttpClient/4.4.1 (Java/1.8.0\_20)"

On first command, there is none user instead on the second one there is `jenkins` user. This user is used to connect Jenkins server to Gerrit server (both ssh and REST API). Is it this the issue ?

What I tried so far

**Reconfigure Gerrit Trigger Plugin under Jenkins**

As [@Marcelo](https://wiki.jenkins-ci.org/display/JENKINS/Sonar+Gerrit#SonarGerrit-Gerrit) mentioned, Sonar Gerrit plugins uses Gerrit trigger. I reconfigure the entire plugin following [Gerrit trigger set up](https://wiki.jenkins-ci.org/display/JENKINS/Gerrit+Trigger#GerritTrigger-SetupRequirements).

I previously missed the step under adding Gerrit access rights for "Label Verified"

> 
> Admin > Projects > ... > Access > Edit 
> 
> 
> Reference: refs/heads/\* Label : Verified: -1, +1 for Non-Interactive Users
>

Detailed explanation on post [Can't find 'Label Verified' permission in gerrit 2.7](https://stackoverflow.com/q/20019195/2394026).

**Remove verified tag send from Jenkins to Gerrit**
As explained in [install documentation](https://wiki.jenkins-ci.org/display/JENKINS/Gerrit+Trigger#GerritTrigger-NotetoGerrit%3E2.6Users) for Gerrit > 2.7.

>

> Under "Gerrit Servers" next to your server(s) click the "Edit" button (looks

> Under "Gerrit Reporting Values" click the Advanced button at the bottom

> 
> Under "Gerrit Verified Commands" remove the '--verified ' sections from each command
