Using https://wiki.jenkins-ci.org/display/JENKINS/Adding+tool+auto-installer as a template, I can see a backend crawler (https://github.com/jenkinsci/backend-crawler) that gets versions of tattletale jars from https://repository.jboss.org/nexus/content/groups/public/org/jboss/tattletale/tattletale/maven-metadata.xml file

Then it can download the jar, and even inspect the pom and get the version of aspectj it needs too. (Possibly making that configurable, defaulting to auto).

Then implementing the classes needed for this plugin to use the backend crawler json file to allow automatic install and configuration of this plugin.

I'll be working on this a little bit here and there, but wanted to get the feature into JIRA.
