The bug with org/jruby/RubyInstanceConfig

Hi everyone,

I am new at AsciiDoc. I am working on a project with Vaadin (Java web framework) and trying to connect Vaadin with Asciidoctor. Need to simple write some sentences in file and get the pdf version.

Here are the logs for the bug I receive:

Here is the code

package com.example.testasciidoctor;

import static org.asciidoctor.Asciidoctor.Factory.create;
import org.asciidoctor.Asciidoctor;
import org.asciidoctor.Options;

import java.io.File;
import java.util.Collections;
import java.util.HashMap;

public class TestAsciiDoc {
       
        public TestAsciiDoc(){
        Asciidoctor asciidoctor = Asciidoctor.Factory.create();

        String rendered = asciidoctor.render("*This* is it.", Collections.EMPTY_MAP);
        System.out.println(rendered);
               
        }
}


I will appreciate any kind of help because I can not continue without the Asciidoctor.

Thank you.

Welcome :)

First, I am assuming you'r using maven or gradle to package your app.

I guess the error is because jruby-complete dependency is defined as "runtime" on Asciidoctorj module.
In your case, since you're deploying to a webapp, libraries as runtime are not included in the final application and thus the error, if you run the class as a main ¿does it work?
To fix it, try adding the dependency in your descriptor, it is maven, add:

        <dependency>
            <groupId>org.jruby</groupId>
            <artifactId>jruby-complete</artifactId>
            <version>1.7.17</version>
            <scope>compile</scope>
        </dependency>

Asciidoctorj can work with other versions, but current stable version is aligned to 1.7.17.

Oh thank you so much, this is the solution. Now it works perfect!

Also, thank you for the warm welcome. :)
