Introduction
There are plenty of CI servers to choose from. We have selected the three from the five most popular from the following poll:
Poll: What Continuous Integration Server are you using in 2008?
and tried to give a rough overview of pros and cons. Note that all three solve the basic task of automating builds, so which server to choose is a matter of personal taste and which properties the development team values the most.
Top three CI servers
- Continuum
Open Source
Easy to install
Gathers 99% of necessary information from the pom.xml. Easy to initate new projects.
Allows grouping of projects (and configuration per group)
Easy to set up different kinds of builds in the same project (Build Definitions)
Supports maven-release from GUI
Large community
Poorly documented
Used to release very seldom
Cross-version migration issues
- Hudson
Open Source
Easy to install
Lots of plugins
Good REST-api
Supports slave agents (easy to set up too)
Frequent releases and great deployment mechanisms (WebStart for instance)
Quick and snappy pages
Good console output
Each job (project) must be configured from scratch. Duplicates configuration when having many jobs for one project (can copy, but not share)
Doesn't scale with number of archived builds (having too large history will slow Hudson down as reports are based on numerous xml files)
- Bamboo

Good documentation
Tidy configuration
Very easy installation procedure
Solid and enterprisey, scales well into many many projects (distributed builds on agents)
Excellent reporting and output capabilities
Supports Continuum-like multpiple "plans" for a single project (prevents config duplication)
Commercial(but not that expensive really)
Aquired taste: Not immediately intuitive GUI
Others
- TeamCity
God integrasjon med IntelliJ
Commercial
- CruiseControl - gammel og akterutseilt, bør ikke velges for nye prosjekter
Open Source
- Anthill OS
Open Source
- Luntbuild

- Apache Gump
Open Source
- QuickBuild (Luntbuild professional)
Commercial
- AnthillPro
