undefined method `encode' for nil:NilClass #11

Closed bannmann closed 6 years ago

bannmann commented 6 years ago

On a linux machine, trying to generate a PDF via Maven results in the following exception:

(NoMethodError) undefined method `encode' for nil:NilClass

Before that exception, I get warnings like this:

The following text could not be fully converted to the Windows-1252 character set:
| ◦

Can this be the cause? Note that the theme does not define any custom fonts (yet).

On Windows, I get similar warnings, but no exception.

The adoc files are saved as UTF-8.

robertpanzer commented 6 years ago

I don’t know if this is the problem, but for asciidoctorj-pdf you need a later version of JRuby. The version should of jruby-complete should be 9.1.12.0 or 9.1.8.0 if you also want to run on windows.

bannmann commented 6 years ago

Thanks a lot, using jruby-complete 9.1.8.0 indeed fixed the problem!

It feels messy that I can't rely on the transitive dependencies alone, but I guess this is caused by something along the lines of asciidoctorj or the maven plugin itself referencing that older version.
