Setting up Sonar-Gerrit plugin : Failed to execute command 'gerrit review ' on UserAtHost

Question

I'm trying to set up the Sonar-Gerrit plugin on a Jenkin job.

Set up

1. Jenkins Maven job is launched when a patch set to Gerrit
2. I see the error in the Jenkins output.

Here is the Jenkins console error output :

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.4.0.905:sonar ( default-cli) on project parent: Failed to execute project builder: fr.techad.sonar.GerritProjectBuilder: Failed to execute command 'gerrit review 298816ea2b24645fd971a8c0833582cec1163dac -j' on UserAtHost@55a9f72f [user=jenkins, host=172.21.33.193, port=29418]: reject HostKey: 172.21.33.193 -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

What I have tried so far

Looking the [Help 1].It says

this exception is not generated by the Maven core itself but by a plugin.

1. I tried to log in the Jenkins server and run "mvn sonar:sonar" in the directory（/usr/share/tomcat/.jenkins/workspace/sonar-maven）.It runned successfully and I could see the results on the Sonar Dashboard.
2. Reconfigure Gerrit Trigger plugin. Then I checked the connection in the Gerrit Trigger,and it sad successful.

Did anyone have this same error? how can I try to fix it?

Software Version

Answer 1

your exception says:

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin

It's your maven plugin for sonar is failing the job, not the sonar-gerrit plugin.

Failed to execute command 'gerrit review 298816ea2b24645fd971a8c0833582cec1163dac -j'

I don't know what does sonarqube command "gerrit review -j" and it looks like that this sonar-maven-plugin doesn't know it, either.

You could try looking into this question - it may help you to configure sonarqube for your project: Why Maven command MVN sonar:sonar works without any plugin configuration in my POM.xml?

Answer 2

The error is:

Failed to execute command 'gerrit review 298816ea2b24645fd971a8c0833582cec1163dac -j'

Sonar-gerrit uses the gerrit-trigger plugin to vote in Gerrit. It seems there is something wrong with the gerrit-trigger configuration. I know you've checked the connection between gerrit-trigger and Gerrit but this is error is related to the "gerrit review" command.

Check the "gerrit review" command at:

Jenkins > Manage Jenkins > Gerrit Trigger > Edit > Advanced... > Gerrit Verified Commands

For example, it works to me with:

gerrit review <CHANGE>,<PATCHSET> --message 'Job finished <BUILDS_STATS>' --code-review <CODE_REVIEW>

After that, if the error persists, log in the Jenkins server and run the "gerrit review" command manually executing:

ssh -p 29418 [email protected] gerrit review

If you get the same error you can try to debug it adding "-vvv" to the command.
