Weeding Your Micro Service Landscape
summary
Automated code transforms using OpenRewrite plus the Moderne Platform/CLI update hundreds of services at once: demo runs 2,000+ evaluated edits in ~20 seconds and reports ~46 minutes of manual work saved; recipes cover 2500 recipes for Java upgrades (Java 8→11→17→21), JUnit4→5, Hamcrest→AssertJ, Spring Boot tweaks, text blocks and pattern matching, and removing stale feature flags. Platform serializes project models to run across dozens of repos (26 Gradle wrapper updates in under a minute) and produces commits/PRs automatically.
