Companies report massive scale problems: one codebase has 500 modules and another had 40–50 minute builds before changes. Teams measure time-to-merge and build medians, use Gradle Profiler for repeatable benchmarks, Graph Assert to find high betweenness modules, and Foundry or custom convention plugins to generate modules. Common-module bottlenecks get class-by-class extraction, plugins get published as binaries to avoid build churn, and some teams migrate to Bazel or watch the Declarative Gradle EAP for long‑term gains.
