Yes, I am working on PR.

The issue names no repository files, tests, or entry points beyond pom.xml. Start with the before-and-after pom.xml examples and determine how dependency and plugin versions should be represented as properties. Done means all applicable versions are declared in properties and their original version elements reference those properties.
