gradle-build-performance

To diagnose slow Android Gradle builds, generate a Build Scan using ./gradlew assembleDebug --scan and analyze the results to identify bottlenecks in the initialization, configuration, or execution phases.

The best way to speed up Gradle configuration time is enabling the Gradle configuration cache, which significantly reduces overhead by caching the project configuration state for subsequent builds.

To migrate kapt to KSP and improve Android build performance, gradually replace kapt annotation processors with KSP processors, then verify the execution time improvements by re-running builds and comparing metrics.

Yes, you can use Gradle build scans to optimize CI/CD pipelines by measuring baseline build times, applying targeted optimizations, and validating improvements by comparing build metrics across pipeline runs.

Gradle build cache misses in CI often occur due to uncacheable tasks or inconsistent inputs; diagnose these specific execution bottlenecks by analyzing your build scan and fixing cache misses to reduce build times.
