Ref Guide builds are also failing due to duplicate section headings on two pages.
https://builds.apache.org/job/Solr-reference-guide-master/5499/console: build-site: [java] ID occurs multiple times: configuration [java] ... file:/home/jenkins/jenkins-slave/workspace/Solr-reference-guide-master/solr/build/solr-ref-guide/html-site/monitoring-solr-with-prometheus-and-grafana.html [java] ... file:/home/jenkins/jenkins-slave/workspace/Solr-reference-guide-master/solr/build/solr-ref-guide/html-site/parallel-sql-interface.html This will cause links between sections of the PDF to go to the wrong place, so each section must be unique. I'd suggest in this case possibly changing the new page section heading "Configuration" to "solr-exporter Configuration" or something similar.
