The versions plugin provides a task to discover dependency updates. It uses an internal api to sort the resolved dependencies into groupings (upgrades, at latest, beyond latest - e.g. snapshots). The comparator was deleted in 1.8, understandably since its not a public class.
What is the best alternative for making this plugin 1.8 compatible? Is it to embed a copy of the comparator, which relies upon ivy classes? Is there a Gradle api that provides equivalent functionality? See the usage for details.
