Essential Tips for Gradle on Ephemeral CI Environments - Part 2

Part 2 of a series on optimizing Gradle builds in ephemeral CI environments focuses on the Configuration phase. Benchmarks on a Spring Boot project show that caching the modules-2 dependency directory cuts build time by 28% (31.5s → 22.7s). The shared read-only dependency cache via GRADLE_RO_DEP_CACHE delivers identical savings while allowing multiple ephemeral runners to share one pre-populated cache without lock contention. Caching compiled Kotlin DSL scripts (kotlin-dsl) saves an additional 10%, with gains scaling up for larger multi-module builds. Caching processed JARs (jars-9) alone yields no measurable benefit. The post also covers how setup-gradle GitHub Action and Develocity's Universal Cache automate these optimizations without manual Dockerfile maintenance.
