asciidoctorj-pdf error when processing

[yami12376]

I have got following error:

[ERROR] Failed to execute goal org.asciidoctor:asciidoctor-maven-plugin:1.5.6:process-asciidoc (output-pdf) on project projectName: Execution output-pdf of goal org.asciidoctor:asciidoctor-maven-plugin:1.5.6:process-asciidoc failed: (SyntaxError) C:/Users/username/.m2/repository/org/asciidoctor/asciidoctorj-pdf/1.5.0-beta.5/asciidoctorj-pdf-1.5.0-beta.5.jar!/gems/asciidoctor-pdf-1.5.0.beta.5/lib/asciidoctor-pdf/core_ext/numeric.rb:3: syntax error, unexpected kDO_BLOCK

                            </dependency>
                        </dependencies>

works fine if I change

   <version>1.5.0-beta.5</version>

to

<version>1.5.0-alpha.15</version>

The same occurs on:

   <version>1.5.0-beta.6</version>

When I change version from 1.5.6 to 1.6.0 it does not immediately give error as in the examples above. Consider giving some matrix telling which version to use.

This looks like an incompatibly with JRuby. Can you figure out which version of JRuby is being used? Try to turn up the verbosity in Maven and search for the string jruby.

[yami12376]

These are the versions of JRuby:

[mojavelinux]

It appears you have multiple versions of Ruby on the classpath. Most concerning is JRuby 1.7.26, which is no longer supported. And that's likely why you're getting the error. You must at least be using JRuby 9.1.

[yami12376]

The comment above was aggregating information and i was changing version in pom.xml.

[mojavelinux]

That's a low-level Ruby language compliance error. It indicates that the JRuby dependency is outdated. I'm not exactly sure what to tell you to change to get the right version of JRuby, but I'm certain that's the problem. Does the example project have the same issue? If not, you could use it as a reference. So that would be something to check first.

[mojavelinux]

Here's a branch that shows that the example works:

asciidoctor/asciidoctor-maven-examples#88

It also works if I test it with these versions:

        <asciidoctor.maven.plugin.version>1.5.6</asciidoctor.maven.plugin.version>
<asciidoctorj.pdf.version>1.5.0-beta.6</asciidoctorj.pdf.version>
<asciidoctorj.version>1.5.8.1</asciidoctorj.version>
<jruby.version>9.2.8.0</jruby.version>

So I think your dependencies have disagreements. I'd need to see a full example to know more.

[abelsalgadoromeroWD]

Noted! I will upgrade all versions for all projects today. I started it, but kindlegen is giving me some headaches on this machine and I want to test all projects manually.I'll do when I get home later (in 9h).

Do you mind If I close this PR?

[mojavelinux]

You can close the PR. I submitted merely as a reference for answering this issue.

[yami12376]

Ok, thanks. I am happy that version 1.6.0 works fine with 1.5.0-beta.6 in my case.
Also note that in the example you provided explicity:
<jruby.version>9.2.7.0</jruby.version>

Which i do not have anywhere in my project.
Are you sure that:
<asciidoctorj.pdf.version>1.5.0-beta.6</asciidoctorj.pdf.version> <asciidoctorj.version>2.1.0</asciidoctorj.version>

Does not provide JRuby?
In my plugin Depedency Anaylyzer i do not see conflict regarding JRuby in the component i use generating pdf with it.

I think that for example:

<groupId>org.asciidoctor</groupId> <artifactId>asciidoctorj-pdf</artifactId> <version>1.5.0-alpha.15</version>

Contains:

    <dependency>
      <groupId>org.jruby</groupId>
      <artifactId>jruby-complete</artifactId>
      <version>9.1.8.0</version>
      <scope>runtime</scope>
    </dependency>

That is JRuby or what?

If i would provide

        <dependency>
            <groupId>org.jruby</groupId>
            <artifactId>jruby-complete</artifactId>
            <version>9.2.8.0</version>
        </dependency>

Then i see conflict in my Depedency Analyzer with jruby-complete.

Probably in version 1.5.0-alpha.18 it is not inside anymore.

[abelsromero]

Does not provide JRuby?

jruby-complete is provided by the maven plugin as a default, is not part of dependencies of asciidoctorj or asciidoctorj-pdf.
We try to use the latest stable version at the time of release unless some problem is found. So it is mostly always good to replace the provided version by the most recent one. In this case going from 9.2.7.0 to 9.2.8.0.

Then i see conflict in my Depedency Analyzer with jruby-complete.

I can't help here, but I assure you it is safe. Also, I recommend to use the latest maven plugin version as shown in the examples. It is a RC, but is perfectly stable.

[robertpanzer]

Please reopen the ticket if the error still occurs with the latest versions of the asciidoctor-maven-plugin, asciidoctorj and asciidoctorj-pdf.
