[jira] [Commented] (SOLR-13424) Ref Guide PDF build throws Java errors after requiring Java 11 on master

["Cassandra Targett (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-13424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16824216#comment-16824216 ] 

Cassandra Targett commented on SOLR-13424:
------------------------------------------

This is from https://builds.apache.org/view/L/view/Lucene/job/Solr-reference-guide-master/15365/ (23 April 2019).

The PDF target has several dependent targets, so runs in stages.

The {{build-nav-data-files}} dependent target produces the following. This is from Hoss' classes, and builds the hierarchical page navigation:

{code}

The {{bare-bones-html-validation}} creates a stripped-down HTML for checking that inter-document links work properly, and is also from Hoss' classes, but uses asciidoctor-ant to do the conversion to HTML (some unrelated messages at the end have been stripped):

> Since the {{master}} branch requires Java 11, the Ref Guide build has started throwing WARNINGs that we should look into. Despite the WARNINGs, the PDF build finishes successfully and appears the same as usual. 
> There are a couple moving parts here - first some classes [~hossman] wrote to validate links in the PDF, and second a .jar from the {{asciidoctor-ant}} project. I suspect some of these are related to Hoss' code and some are from the project that's doing the PDF conversion.
> I'll put the output from a Jenkins job in the comment to show the errors.
