Build bigger, better: Gradle for large projects

on YouTube ↗37m

" summary

AndroidX grows from 5 to 240 Gradle projects and 90k to 400k lines of code, so the talk explains concrete fixes: centralize dependency versions with a buildSrc Kotlin module, replace repeated 150-line build.gradle files with ~35-line modules via a custom plugin DSL, use lazy APIs (Property, DirectoryProperty, flatMap), prefer Worker API and custom task types, and measure with Build Scans and a homegrown Tracer Agent; experiments pick an ~8 GB JVM for best build vs GC tradeoff.
