The error is because `require` is used to load Ruby gems, and mathJax is pure javascript. So it's not finding the expected files.
As far as I know mathJax uses a script post-processing to render the images in HTML, so it may not be suited for PDF. Not at least with `asciidoctor-pdf`.

If you explain what are you trying to achieve maybe we can work some alternative. For example, is maven and mathjax a must?
Also someone at the gitter channel could help https://gitter.im/asciidoctor/asciidoctor.
