A detailed comparison of Gradle and Bazel as build tools for JVM projects, covering performance benchmarks across full builds, remote caching, and incremental builds for small, medium, large multi-project, and monolithic codebases. Key findings: Gradle outperforms Bazel in nearly every tested scenario, especially for incremental builds on monoliths (5-16x faster). Bazel's recommended fine-grained per-package build files offer performance gains but impose heavy migration and maintenance costs. Gradle also wins on dependency management (rich transitive dependency handling), JVM ecosystem integration (Spring Boot, Kotlin, JUnit 5), IDE support, and plugin ecosystem size. Bazel's strengths lie in polyglot support and extremely large monorepos like Google's internal codebase.
