  • 1. First, a developer commits code to the version control repository. Meanwhile, the CI server on the integration build machine is polling this repository for changes (e.g., every few minutes). 2. Soon after a commit occurs, the CI server detects that changes have occurred in the version control repository, so the CI server retrieves the latest copy of the code from the repository and then executes a build script, which integrates the software. 3. The CI server generates feedback by e-mailing build results to specified project members. 4. The CI server continues to poll for changes in the version control repository.

  • 2. Outline
    • Towards a better build process using agile tools
    • Build Managements
    • Continuous Integration, Principles and Tools
    • JasForge project
    • Using hudson in jasforge Project
    • Demos
  • 3. TOWARDS A BETTER BUILD PROCESS USING AGILE TOOLS
  • 4. Build is often a hard process
  • 5. What Is a Build?
    • A build is much more than a compile (or its dynamic language variations)
    • A build may consist of the compilation, testing, inspection, and deployment—among other things
    • A build acts as the process for putting source code together and verifying that the software works as a cohesive unit.
  • 6. The Integrate button Source : Continuous Integration by Paul M. DUVALL
  • 7. Why using Build Tools?
    • Builds are messy
    • Builds are hard
    • It is hard to learn how to do them “right” - what is “right” by the way?
    • Builds are typically not well documented
    • Trial and error
    • ... and you often run out of bamboo ...
  • 8. Build Tools Automation in a agile scenario CI Build Server Automated testing Automated code quality Build Tool
  • 9. Build Tool
    • Collect input
    • Process inputs
    • Generate final outputs
  • 10. Build Tool - Inputs
    • Source code
      • Java, SQL
    • Resources
      • Properties, XML
    • Dependencies
      • Libraries, components, frameworks
  • 11. Build Tool - Processing
    • Compile
    • Run tests
    • Copy files
    • Replace keywords
    • Package
    • Install / deploy
  • 12. Build Tool - Outputs
    • JAR / WAR / EAR files
    • Zip files
    • Reports
  • 13. What is the primary build tool and release management you typically use ? Source: Eclipse community Survey
  • 14. Maven
    • Project and artifact-based build platform
    • Uses repositories to manage artifacts and third party libraries
    • Customized by modifying the behavior of the life-cycle via plugins.
  • 15. Maven and the Development Build Process
    • Maven the source build management tool for enterprise Java projects
    • Use declarative approche rather then the task-based approach used in Ant or in traditional Make files or shell scripts
    • Promotes the use of standard directory
    • structures and a well-defined build lifecycle
    • Support quality metric reporting and
    • documentation generation tool throw the use
    • of plugins
  • 16. Phases: build life cycle
    • The standard goals for building:
      • compile & test - compile and test the code
      • package – build and test the artifact
      • install – package the artifact and install to local repository
      • deploy – package the artifact and copy to the remote repository (release time)
    • Release management
  • 17. Common way to build applications MOJO – Maven 2 Plugins Project http://mojo.codehaus.org/ plugins user e.g. mvn install M2 generate- sources compile test install deploy package integration- test Well-known phases mojo mojo mojo mojo mojo bindings
  • 18. CONTINUOUS INTEGRATION PRINCIPLES AND TOOLS
  • 19. What is CI (Continuous Integration) ?
    • “ Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily - leading to multiple integrations per day. Each integration is verified by an automated build (includingtest) to detect integration errors as quickly as possible.”
    • Martin Fowler.
  • 20. Continuous Integration (CI) scenario
  • 21.
    • A CI scenario starts with the developer committing source code to the repository.
    • On a typical project, people in many project roles may commit changes that trigger a CI cycle:
      • Developers change source code,
      • database administrators (DBAs) change table definitions,
      • build and deployment teams change configuration files,
      • interface teams change DTD/XSD specifications,
      • and so on…
    Continuous Integration (CI) scenario
  • 22. Why do we need CI ?
    • Replace big (and long) integration phases with small and frequent ones
      • Ideally instantaneous
      • Think of « incremental compilation » in Eclipse
    • Minimize integration effort
      • Keep the development process running …
    • CI was introduced with XP principles and by Martin Fowler
  • 23. The components of a CI system Commit changes Compile Source Code, Integrate Database, Run Tests, Run Inspections, Deploy Software Feedback Mechanism Generate feedback SCM Server (Svn, Git, …) CI Server
  • 24. Workflow
    • Checkout from SCM
    • Code a new feature
    • Run automated build on my machine
      • Repeat 2 and 3 until test pass !
    • Merge with latest changes from SCM
      • Fix and rebuild until test pass
    • Commit
    • Run a build on a clean machine
      • Immediately fix bugs and integration issues
  • 25. Version Control Repository
    • Simply put, you must use a version control repository in order to perform CI
    • Even if you don’t use CI, a version control repository should be standard for your project
    • The purpose of a version control repository is to manage changes to source code and other software assets (such as documentation) using a controlled access repository
    • There are different types of version control systems you can use too
    • We use Subversion for most of the examples in this seminar
  • 26. Continuous Integration not exist without TDD !
    • A software development practice where members of a team integrate their work frequently usually each person integrates at least daily (Martin Fowler)
    • CI leads to significantly reduced integration problems and allow a team to develop cohesive software more rapidly and reduce risk
    • To complete this definition
      • Automated, self-testing and fast builds
      • Make it easy for everyone to get the last executable
      • Automate deployment
      • Everyone can see what’s happening progress, statistics on code coverage tests, etc …
      • Reduced risks
  • 27. Continuous Integration
    • Major tools
      • Hudson
        • No install required put a war in a web container)
      • Cruise Control
      • Continuum
        • Java and Ant/Maven based
        • Open Source
  • 28. Every commit much triggers a build !
    • Commit at least daily…
      • As soon as you have completed an independent functionnality
    • A full build on another empty machine
      • Not on your own !
    • With hudson
      • SCM polling
      • Cron-like scheduller
      • Trigger with http request (from maven or svn commit hook)
  • 29. JASFORGE © PROJECT AND HUDSON CI TOOL
  • 30. Managing all the agile tool is a complex process
    • Today, managing and taking control of your software process is a major challenge for maintaining is capacity to be innovative and competitive
    • Ho can we manage efficiently all these toolls in an unified way ?
    • We must manage the quality of our software development en meet the requirements and delays in a predictive mode
    • This is the aim of JasForge © Project ( http://www.jasforge.com ) : Taking the control of your development process using an “agile “ approache
