Compatibility with newer Java versions
I try to use the org.asciidoctor.jvm.gems plugin which uses this plugin under the hood.
When executing the AsciidoctorGemPrepare task which extends AbstractGemPrepareTask while executing Gradle with Java 17, you are warned with
WARN FilenoUtil : Native subprocess control requires open access to the JDK IO subsystem
Pass '--add-opens java.base/sun.nio.ch=ALL-UNNAMED --add-opens java.base/java.io=ALL-UNNAMED' to enable.
which is not "easily" work-aroundable due to #14.
