I am using groovy scripts copied to /usr/share/jenkins/ref/init.groovy.d/ to do the initial setup of a Docker Jenkins instance. Later I create jobs using the Job DSL Plugin that require Xvfb.
I can't figure out how to initialize a "default" installation of Xvfb using groovy scripts. I have a work-around where I put a copy of org.jenkinssci.plugins.xvfb.XvfbBuildWrapper.xml and then in the groovy scripts I have one script that runs "Jenkins.instance.doReload()". This broke when I upgraded from 1.0.6 to 1.1.3 since the format of the xml file changed.
What is the right way to script the creation of a default Xvfb installation?
