Continuous integration: The Players
• Source code– incremental changes are stored – trunk, tags
• Contains all projects, monitors subversion for changes, starts build cycle
• Manages build– build cycle (clean, compile, test, package,
deploy, integration-test, ?web-test?) – dependencies (3d party, in-house, blackboard)– parent pom– plugins
invivodeploy plugin

10 Practices of CI (M Fowler)
• Maintain a Single Source Repository • Automate the Build• Make Your Build Self-Testing• Everyone Commits To the Mainline Every Day• Every Commit Should Build the Mainline on an
Integration Machine• Keep the Build Fast• Test in a Clone of the Production Environment• Make it Easy for Anyone to Get the Latest
Executable• Everyone can see what's happening• Automate Deployment
