Make Your Build Great Again
summary
Optimizes a large multi‑dex Android build for Yammer by changing Gradle properties, plugin versions and JVM args, enabling Gradle build cache, using parallel test workers, switching tests to Genymotion, toggling pre‑dex on CI, trimming repositories and dynamic deps, forcing support libs, and enabling the D8 dexer and Java 8. CI cold builds fall from ~18 to ~11 minutes (~40% faster); merging some modules saves ~2 minutes more, and Gradle Profiler / scans confirm the improvements.
