Documentation for Maven Plugin classifier has an unresolved external reference

[mgiorgino]

There is what seems to be a failed template replacement at the end of the documentation about the classifier configuration option of the spring-boot-maven-plugin: see $1[$2]:

https://docs.spring.io/spring-boot/docs/2.5.x/maven-plugin/reference/htmlsingle/#goals-repackage-parameters-details-classifier
https://docs.spring.io/spring-boot/docs/2.6.2/maven-plugin/reference/htmlsingle/#goals-repackage-parameters-details-classifier

Thanks for the report, this is a <a href instruction in the javadoc that our asciidoctor processor doesn't seem to handle.

The text in the plugin.xml that's used to generate the Asciidoctor source has been HTML escaped so <a href=" has become <a href=&quot. This is also the case in 2.2 so it looks like Maven's site support copes with this escaping but our Asciidoctor-based documentation does not.
