Faster Feedback Cut Gradle Build and Pipeline Times in Half

on YouTube ↗32m

" summary

Claims a reproducible 50% reduction in Gradle and CI times on a production Android app by changing gradle.properties, upgrading JDK and Kotlin, and swapping annotation processing to KSP instead of KAPT. Shows measured wins like a local run dropping from 3:15 to 2:28 and a pipeline collapsing from 12 to 6 minutes after merging stages and enabling parallel jobs. Covers concrete tactics: repository ordering, pinning versions, Gradle caching and daemon settings, lightweight CI images and shared caches, and using the Gradle build scan/profiler to benchmark each change.
