Jenkins setup demonstrating the JAXB API plugin usage on Java 11

Starting with Java 9+, JAXB is not available anymore by default in the JDK.

This Jenkins Docker image demonstrates that the https://github.com/jenkinsci/jaxb-plugin/ allows to fix the ClassNotFoundException we would normally encounter.

Use this image

• Run it on Java 11

docker run -p 8080:8080 -ti batmat/jaxb-java11-demo

• Open the browser on http://localhost:8080

• Login as admin:admin

• Install the sloccount plugin through the plugin manager UI ^[1]

• Start the count-loc job

• See it succeeds, despite running on Java 11 without any java 11 specific flag (i.e. no --add-modules)

To run it on Java 8

docker run -e JAVA8=yes -p 8080:8080 -ti jaxb-java11-demo

1. this must be done this way because preinstalling plugins in the Docker image would not install implied dependency, which JAXB is.
