    Project mention: Modularizing Your Android Build with Convention Plugins and Version Catalogs: The Gradle Architecture That Cuts CI Time in Half | dev.to | 2026-04-16

    ## Gotchas - **Modularization is a graph problem, not a counting problem.** 40 modules in a linear chain are worse than 10 modules in a flat graph. Run `./gradlew :app:dependencies` and break feature-to-feature edges. - **Use `api` vs `implementation` strictly.** Feature modules should never expose transitive dependencies to other feature modules — because they should never depend on each other. - **Configuration cache requires dropping buildSrc.** You cannot get meaningful cache hit rates while `buildSrc` is in play. This is the single highest-ROI change you can make. - **Clean build times improve less dramatically than incremental ones.** Expect clean builds to go from 8m 12s to around 5m 48s. The real payoff is in the incremental cycle you hit hundreds of times per day. ## Wrapping Up Start with the `build-logic` migration — it typically takes a day and unlocks configuration caching immediately. Then flatten your dependency graph so feature modules only reach down to `:core-*` modules. Finally, move version catalog bundle references into your convention plugins. I've watched teams accept 20-minute CI runs for months because "that's just how Gradle is." It isn't. A day of restructuring paid back within a week on our team. For further reading, check the [Gradle composite builds docs](https://docs.gradle.org/current/userguide/composite_builds.html) and the [Now in Android](https://github.com/android/nowinandroid) project, which implements this exact pattern at scale.
