Bug with empty adoc files / only a first row title

[cbouveresse]

Hi,

I've been looking to debug the following build failure in my Asciidoctor Maven project (plugin version 1.5.2.1) for 2 hours... And I've finally found a simple issue on asciidoctor pdf.

BUILD FAILURE:

[ERROR] Failed to execute goal org.asciidoctor:asciidoctor-maven-plugin:1.5.2.1:
process-asciidoc (generate-pdf-doc) on project asciidoctor-pdf-example: Executio
n generate-pdf-doc of goal org.asciidoctor:asciidoctor-maven-plugin:1.5.2.1:proc
ess-asciidoc failed: (NoMethodError) undefined method `margins' for nil:NilClass

Let's explain the issue with the asciidoctor-pdf-example from Asciidoctor Maven Examples.

Let's modify the content of a random .adoc file from this project:

If I empty the file content , build failure:

If I only put a main title in this in the file, build failure:

= Main Title

If I only put a second title content in the file, build success:

== Main Title

If I put a main title with content in the file, build failure:

= Main Title
a

If I put a main title, skip a line, and put content in the file, build success:

= Main Title

a

I therefore suppose this small issue comes from Asciidoctor PDF ! HTML works well.

This definitely seems like an Asciidoctor PDF issue. I'll mark it as a bug and schedule to get it fixed for the beta.

This was fixed by 31d7c27, which was included in the alpha.13 release.
