Automate library migrations with OpenRewrite

Backwards incompatible library changes. Sometimes they’re just forced upon you and there is no way around it (looking at you Jakarta). Sometimes you choose them yourselves, because the API of your internal library was a little too broken. No matter what the cause: it’s a pain to do and verify all the changes required in your big microservices landscape. Enter OpenRewrite. With OpenRewrite you can create recipes that you can then use to automatically apply all required changes to your code base. There are tons of predefined recipes already, and you can even write your own in Java. In this session I will show you what OpenRewrite can (and can’t) do for you.
