Gradle Build Performance

Workflow

1. Measure baseline — clean build + incremental build times
2. Generate a Build Scan — ./gradlew assembleDebug --scan
3. Identify the slow phase — Configuration? Execution? Dependency resolution?
4. Apply one optimization at a time — don't batch changes; you won't know what helped
5. Measure again — confirm improvement before moving on
