Keeping your Gradle builds in top shape

Which tasks are the slowest running tasks?
Who has the slowest builds on my team?
Which task is getting the most cache misses?
These questions and more can be easily answered with the new Gradle Enterprise API.
Come learn about how to automatically check your build's cacheability and find out who on your team is suffering the most painful builds.

1. Keeping your Gradle builds in top shape Nelson Osacky
2. Me • Previously Android Engineer • Large projects • SoundCloud • Square • Small startups • Gradle Plugin Maintainer • Fladle - Easily Scale Instrumentation Tests on Firebase https://github.com/runningcode/fladle • Gradle Doctor - Actionable Insights for your build https://github.com/runningcode/gradle-doctor Lead Solutions Engineer
3. I see a lot of builds from 10 person teams to 1000+ Android, Gradle and Maven
4. • Optimize and understand builds • Increase build stability • Preach Developer Productivity
5. • Improve Gradle ecosystem • Fix issues in open source plugin affecting customers
6. • Meet with Google and Jetbrains to help prioritize issues impacting customers
8. Android Development Feature Development Tech Debt (There are other things too)
9. Tech Debt Refactoring Improving builds
10. Slow builds are Tech Debt And it always pays off
11. Cost of Builds 60s waste * 50 builds / day * 50 devs 
 = 42 hours lost / day
12. Cost of Builds 60s waste * 50 builds / day * 50 devs 
 = 42 hours lost / day not including lost focus https://gradle.com/roi-calculator
13. Fast Builds Matter
14. Cost of Builds 60s waste * 50 builds / day * 50 devs 
 = 42 hours lost / day hire 5 new people without paying them! no recruiting https://gradle.com/roi-calculator
15. Slow builds are Tech Debt And it always pays off And is easy to justify working on it

18. How many have seen or used a Build Scan?
19. How many are Gradle Enterprise customers?
20. https://gradle.com/enterprise-customers/oss-projects/ Gradle Enterprise OSS Projects
21. Quick Demo https://ge.androidx.dev/scans
22. What is build caching? https://docs.gradle.org/current/userguide/build_cache.html
23. JavaCompile task Source Files Compiler Args Dependencies Class files any task can be made cacheable
24. Cache key Source Files Compiler Args Dependencies
25. Cache key Source Files Compiler Args Dependencies Build cache Class files
27. Build Validation Scripts
28. Build Validation Scripts 1. Verify up-to-date checking (incremental build) 2. Verify local cacheability 3. Verify cache relocateability 4. Verify CI to CI cache relocateability 5. Verify CI to Local machine cache relocateability
29. Build Validation Scripts 01-validate-incremental-building.sh 02-validate-local-build-caching-same-location.sh 03-validate-local-build-caching-different-locations.sh 04-validate-remote-build-caching-ci-ci.sh 05-validate-remote-build-caching-ci-local.sh
30. •Interactive mode with -i ./01-validate-incremental-building.sh -i •Command line invocation Build Validation Scripts
31. ./01-validate-incremental-building.sh 1. Disable build caching completely 2. Run the build with a typical task invocation including the 'clean' task 3. Run the build with the same task invocation but without the 'clean' task 4. Determine which tasks are still executed in the second run and why 5. Assess which of the executed tasks are worth improving 6. Fix identified tasks Step 1-3 are automated. 4-6 are manual.
32. ./01-validate-incremental-building.sh 2. ./gradlew clean assemble --no-build-cache 3. ./gradlew assemble --no-build-cache

97. Old Export API https://docs.gradle.com/enterprise/export-api/
98. How many are are familiar with the Export API?
99. Old Export API • SSE based • Real time streaming • JSON events • No event model • Clunky
100. Old Export API https://«gradle-enterprise-host»/build-export/v2/builds/since/1466640000000
102. Old Export API https://«gradle-enterprise-host»/build-export/v2/build/gkoprlkauv35q/events
104. New Gradle Enterprise API https://docs.gradle.com/enterprise/api-manual/
105. Gradle Enterprise API • REST style API • JSON • OpenAPI - allows model and client generation • Build API • Build Cache Node API • Will replace export API - missing raw build events
107. Use cases • Find projects with longest build times • Rank teammates by slowest average build time • Find builds with remote caching errors • Find slowest tasks on average • Find longest non-cacheable tasks in all projects
108. How to? • Swagger generates models and client for you
