The document discusses improving the build and release process for a monolith Java application from taking half a day down to half an hour by moving from Maven to Gradle. It outlines the challenges with the previous Maven build process that took 2.5 to 5 hours to complete full builds and releases. The new process with Gradle enables incremental and parallel compiling, deploy scripts in Groovy, unit testing build scripts, and producing release versions in under 30 minutes with snapshots for faster iterations. Jenkins is configured with Gradle plugins to automate the build, test, release and deployment pipeline.

- 1. THERE IS NO SNAPSHOT How we changed a full release from half a day to half an hour
- 2. IN THIS EPISODE Compile once Gradle
- 3. DISCLAIMER It’s mostly JVM, but the essence is transferable to other languages
- 4. BACKGROUND • Monolith • 46 modules • about 2100 .scala
- 5. • Build • Test • Integrationtest • Release • Deploy • Maven
- 6. COMPILE, COMPILE, COMPILE Compile + test Integration-test mvn release
- 7. COMPILE, COMPILE, COMPILE Compile + test Integration-test mvn release 25-60 mins 50-120 mins 60-120 mins
- 8. SUM • min 2h 30 mins • at times 5 hours or more • parallel builds == crash
- 9. THINK NEW
- 10. HOW?
- 11. COMPILE, COMPILE, COMPILE Compile + test Integration-test mvn release
- 12. COMPILE, COMPILE, COMPILE Compile + test Snapshots
- 13. COMPILE, COMPILE, COMPILE Compile + 1.10.69 test major.minor.buildnumber

- 44. git tag v0.9.3
- 45. Keep build forever (look Ma! No Nexus/Artifactory!)
- 46. CLEAN, COMPILE, TEST,INTEGRATIONTEST • avg = 25 mins • spikes at 30+ mins when pull requests starts to build at the same time • All builds have final release version • who broke the build?
