Html report link isn't appearing in dashboard

Question

I have an HTMl report that needs to be viewable from the Jenkins dashboard. The report is getting archived successfully as indicated in the console output though. My script looks like:

      post {
            always {
                archiveArtifacts '**/target/*.tar.gz'

                publishHTML([allowMissing: false,
                             alwaysLinkToLastBuild: false,
                             keepAll: false,
                             reportDir: 'target',
                             reportFiles: 'dependency-check-report.html',
                             reportName: 'OWASP Dependency Check Report',
                             reportTitles: ''
                ])
            }
