Description

In https://github.com/asciidoctor/asciidoctor-maven-plugin we inject a MavenProject to obtain addition configurations from the pom.xml (https://github.com/asciidoctor/asciidoctor-maven-plugin/blob/a4d86a949643ab68c124fd4c1b9b936412637d93/src/main/java/org/asciidoctor/maven/site/AsciidoctorDoxiaParser.java#L54).
This works fine with site:site, but when using site:run and accessing one of the Asciidoc generated pages we get the error below.
I saw that:

• The error occurs when trying to retrieve the instance of the MavenProject.
• Behavior is the same if I directly inject the MavenProject instead of using a provider. That is, site:site works, site:run fails because it cannot find the instance.

HTTP ERROR 500

Problem accessing /hello.html. Reason:
