We want to go to the failed job, and click the link in the left margin to see which test failed.

Here is our pipeline step:

post { 
  always {
    publishHTML([allowMissing: true, alwaysLinkToLastBuild: true, keepAll: false,   reportDir: 'xxx/target/site/serenity/', reportFiles: 'index.html', reportName: 'Integration Tests Report', reportTitles: 'Integration Tests Report'])
    cleanWs() 
  }
}

There are logs :
 
[Pipeline] { (Declarative: Post Actions)[Pipeline] publishHTML[htmlpublisher] Archiving HTML reports...
[htmlpublisher] Archiving at PROJECT level /xxx/target/site/serenity to /xxx/branches/PR-41/htmlreports/Integration_20Tests_20Report
