It is not possible for me to propose a new version of the change directly on
asciidoctor-maven-examples/pull/12. (Pull requests are fork & branches based. I am used to the gerrit workflow).
I have opened a new pull request for that:
asciidoctor-maven-examples/pull/37I think this will close all open issues concerning diagram in the asciidoctor-maven-examples.
To definitively close the subject, help is appreciated on the
ruby extension from a maven build topic.
