Top Build Performance issues in Android projects - 2023 Edition
summary
Shows concrete causes and fixes for slow Android builds: repeated build caching misses from path sensitivity (KSP, Room), a JDK bug where URL.hashCode changes serialization so Dokka switches to URI, and Gradle 8.1’s stricter configuration cache inputs that required AGP 8.1.1/8.2 fixes for kapt. Demonstrates using Gradle Enterprise build scans and custom task input logging to find mismatched inputs, and new visibility into artifact transforms in GE 23.1 + Gradle 8.1 to trace previously invisible work.
