Managing the chaos: Automating internal dependency upgrades with OpenRewrite
– Room 7
Foredragsholder
Om sesjonen
We build a lot of microservices where common functionality is extracted into shared, innersource libraries. We manage 30+ of these libraries used by dozens of downstream applications or other libraries. Sometimes we need to break the API or require new configuration.
In these cases, version bumps alone are rarely enough. Tools like Dependabot can update dependencies, but they cannot refactor code, migrate configuration, or make breaking changes explicit. Engineers are left to read changelogs, hunt through compile errors, and reapply the same fixes across repositories. And, worst of all, many teams will probably need to do the same thing.
That’s why we decided to stop just managing version bumps and instead automate the refactoring itself. We adopted OpenRewrite to define custom recipes that automatically apply changes. Breaking changes became executable migration guides instead of documentation no one reads.
In this talk you will learn how to set up OpenRewrite for internal libraries. Build and test your custom recipes.
