This conference talk at Devoxx Greece 2025 explores strategies to significantly improve Maven build performance before considering a migration to Gradle. Learn why Gradle offers performance advantages but understand the organizational challenges of migration, including release management, CI/CD pipeline adjustments, and training requirements. Discover practical Maven optimization techniques starting with fundamental improvements like selecting the appropriate JDK, upgrading to Kotlin 2.0 K2, and eliminating unnecessary artifact builds and deployments. Explore advanced solutions including Apache Build Cache and Develocity extensions, converting code generation into jar dependencies to enhance IDE experience, and understanding Maven Reactor's internal workings with multi-module projects. Identify the critical role of modularization in build performance, learn to detect bottlenecks, and implement effective modularization strategies. While these 35-minute session insights may ultimately support a Gradle migration decision, the optimization techniques presented will benefit both Maven and Gradle projects.
