Common Cache issues in Android projects - 2023 Edition
summary
Practical checklist of reproducible cache failures and fixes for Android Gradle builds: absolute paths and live-edit live literals embed user-specific paths causing cache misses; KSP uses internal sub-plugin options and is fixed by a merged PR (KSP sub-plugin options fix); JDK runtime differences are normalized to eliminate non-deterministic transform outputs; CI/local Gradle property mismatches and version-catalog accessor hash changes explain many misses; configuration-cache break with kapt on Gradle 8.1 is reproducible by attaching a debugger; observed 60% reduction in heap/process load when remote caching is working; artifact transforms are now visible in build scans.
