The history of
Nuxeo 5.1 — CI architecture and usage
●
Speed up build time
●
Organize teams resources
●
Ensure publicly available artifacts quality
●
Isolate internal and external build chains
●
Enforce rules for developers
●
Early use of CI
●
Think about what kind of build (Maven, Shell, Ant, …) and what
must be checked for validation (unit tests, errors in logs, …)?
●
Automated build: nothing specific or contextual to the slave
●
Make the build self-testing
●
Stay tuned, be aware of CI activity
●
Never let a project in an unstable status
