After one year of regular work on our build mechanism and Continuous Integration infrastructure, we are able to provide RCP products, along with their complete test suite, more than 3 times faster than before. And guess what, we are using less physical resources. The path to this result was quite long and sometimes tedious, but we finally managed it. I will share our experience and provide tips so you can speed up your own build. I will also mention which improvements are coming. I will explain the methods used to identify bottlenecks and which technical solutions we applied (and the ones we dropped). This talk will go through the usage and possibilities brought by Tycho, Target Platforms, Hudson/Jenkins with some of its plugins and a Maven Repository Manager.

11. Methodology and Technology
Through the path
©2013 Bonitasoft 11

12. Workforce
• Along the way
• 1 year
• Dedicated part-time “Build engineer” at the
end
©2013 Bonitasoft 12

13. Tycho
• PDE build  Tycho
• Easier Modularization
• Help from non-Eclipse RCP developer
– 2  20+
• Easier for Bonita Community
©2013 Bonitasoft 13

14. Modularization
• Easier to split
• On-demand/nightly build:
– Translations
– Patched plugins
– Generated code
– Installers
©2013 Bonitasoft 14

15. Mirrored Target Platform
• Avoid network latency
• Remove external dependencies
– LTS
– Stay the master
©2013 Bonitasoft 15

16. Remove virtualization
• I/O access
• Virtualization killed SSD performance
• Tried
– mounted partition
– Logical Unit
©2013 Bonitasoft 16

17. Backup
©2013 Bonitasoft 17
• Environment and CI config stored on
– Less down time
– Easier to modify environment

18. Jenkins Scriptler plugin
• Allow “complex” build flow
• Easier to test a subpart
• Rejected:
– build-pipeline-plugin
– join-plugin
– Downstream/Upstream

19. Don’t sleep while testing!
• bot.sleep()  bot.waitUntil()
• Gain:
– Stability
– Speed

20. Genisoimage
• Generate .dmg

22. The key of success
©2013 Bonitasoft 22
• Fail Fast
– Easy roundtrip
– Subpart testing

23. What’s next?
Harder, Better, Faster
©2013 Bonitasoft 23

24. Others
• Tycho
– TP resolution
– Young project
• Test split
– Slow/fast
– Enough confidence on a smaller set?
• Translations
– BND use
– Avoid TP resolution
• Workflow Integration in Hudson/Jenkins
