Are you interested in contributing this recipe to OpenRewrite?

Sure.

Note from @timtebeek in Slack channel:

1 hour ago you can probably compile most of that migration by adding core recipes from the marketplace to the recipe builder

Thanks for logging this as an issue @mbucc ! Any implementation I'd expect to be similar to how we support spring cloud and spring batch migrations currently, as mostly yaml recipes composed together, with some tests added to ensure it all works. Here's an example for Spring Cloud: https://github.com/openrewrite/rewrite-spring/blob/main/src/main/resources/META-INF/rewrite/spring-cloud-2022.yml

Let me know if you'd need any help with an implementation! The testing setup would likely require the addition of the dependency and then running ./gradlew downloadRecipeDependencies, as per our documentation on using multiple versions, which we heavily use in rewrite-spring. Other than that it should be straightforward to get started on a draft PR; that way we're able to help out if you get stuck in any way.
