24. it all started with...
29. and now the space is crowded...
30. Software tools for continuous integration include: ▪AnthillPro — continuous integration server by Urbancode ▪Apache Continuum — continuous integration server supporting Apache Maven and Apache Ant. Supports CVS, Subversion, Ant, Maven, and shell scripts ▪Apache Gump — continuous integration tool by Apache ▪Automated Build Studio — proprietary automated build, continuous integration and release management system by AutomatedQA ▪Bamboo — proprietary continuous integration server by Atlassian Software Systems ▪BuildBot — Python/Twisted-based continuous build system ▪BuildMaster — proprietary application lifecycle management and continuous integration tool by Inedo
31. NAnt, Maven, and shell scripts ▪Software Configuration and Library Manager — software configuration management system for z/OS by IBM Rational Software ▪QuickBuild - proprietary continuous integration server with free community edition featuring build life cycle management and pre-commit verification. ▪TeamCity — proprietary continuous-integration server by JetBrains with free professional edition ▪Team Foundation Server — proprietary continuous integration server and source code repository by Microsoft ▪Tinderbox — Mozilla-based product written in Perl ▪Rational Team Concert — proprietary software development collaboration platform with built-in build engine by IBM including Rational Build Forge
32. ➡Humans should do the intelligent work ➡Integrate with source code, metrics Continuous Integration
33. 473 plugins
36. ➡Gradle ➡Jenkins ➡Sonar ➡Maven 3 ➡VisualVM ➡BTrace
37. ➡Sonar

41. ➡For managers? Metrics
42. ★Checkstyle ★PMD ★ Findbugs ★ Cobertura ★ Emma ★ Clirr ★ JaCoCo ★ Useless Code ★ SQALE ★ 20+ others...
