the plugins and extensions are modeled after jruby-gradle and uses the old jruby maven plugins under the hood but it needs jruby-1.7.19 or newer (including jruby-9.0.0.0 serie).
even though the plugin depends on the old jruby-maven-plugins it has a different version.
to see the java/jruby command the plugin is using (for example with the verify goal)
mvn verify -Djruby.verbose
to quickly pick another jruby version use
mvn verify -Djruby.version=1.7.20
it install the gems and jars from ALL scopes and the plugin sections and can execute ruby. execution can be
- inline ruby:
-e 'puts JRUBY_VERSION' - via command installed via a gem:
-S rake -T - a ruby script:
my.rb

java -jar my.jar my.rb

it produces the same jar as with jruby9-jar-plugin but the configuration is more compact using a maven extension.
