Hi Ann,
I think I solved it a couple of hours ago as you mention. I had to remove the sonar analysis lines from the last build of the job, like:
<hudson.plugins.sonar.action.SonarMarkerAction plugin="sonar@2.14"/>
<hudson.plugins.sonar.action.SonarAnalysisAction plugin="sonar@2.14">
<installationName>Sonar01</installationName>
<installationUrl>https://sonarqube-legacy.url</installationUrl>
<ceTaskId>AYaANsjxbLEQIcp9XcS0</ceTaskId>
<url>https://sonarqube-legacy.url/dashboard?id=some.parent.jobt</url>
<serverUrl>https://sonarqube-legacy.url</serverUrl>
<isNew>true</isNew>
<isSkipped>false</isSkipped>
</hudson.plugins.sonar.action.SonarAnalysisAction>
After removing such line I had to reload the Jenkins job, I did it via console script with
Jenkins j = Jenkins.get()
def job = j.getItemByFullName("PROJECT_NAME")
job?.doReload()
That did the trick!
Thanks for your support.
