My presentation on Maven for the Durban Java User Group meeting, held at Thumbtribe's offices. As I'm not happy with everything as-is, my aim is to improve the presentation with an accompanying project which I need to set up in a proper environment so that it can serve as a fully functional example. To follow progress, keep an eye on the following blog post:

Maven: from Scratch to Production (.pdf)

  1. 1. MavenFrom Scratch to Production by: Johan Mynhardt | Durban JUG Meeting | 12 May 2011|
  2. 2. What this is *not*• Ripe ground for flame-war• Argumenting that: • X is better than Y. • Y is better than X. • I can do this with X by making use of Z.• A session to convince you
  3. 3. Objectives• Set up a Maven project• Set up the CI environment with Apache Continuum• See everything in action!
  4. 4. Project Technologies• Java EE 6 • Glassfish Application Server • EJB 3.1 • JSF 2.0 • PrimeFaces• Continuous Integration and Project Management (from development perspective) • Apache Continuum • Apache Maven
  5. 5. Mavens Objectives• Making the build process easy• Providing a uniform build system• Providing quality project information• Providing guidelines for best practices development http://maven.apache.org/what-is-maven.html
  6. 6. Setting up the Project: HelloWorld• Create the project root by running the following: ~/$ cd workspace ~/$ cd workspace ~/workspace$ mvn archetype:generate ~/workspace$ mvn archetype:generate -Dversion=1.0-SNAPSHOT -Dversion=1.0-SNAPSHOT -DgroupId=za.co.thumbtribe.djug -DgroupId=za.co.thumbtribe.djug -DartifactId=HelloWorld -DartifactId=HelloWorld• Select the number for the line matching (in this case 110): 110: remote -> maven-archetype-quickstart (An archetype which 110: remote -> maven-archetype-quickstart (An archetype which contains aasample Maven project.) contains sample Maven project.)• This will be the root of the project, containing the web, service and assemble sub-modules (multi-module project) • You now have the chance to add project-specific documentation and parameters to the pom.xml which you can later on, share with you developers. The convenience is that you dont need to keep track of every aspect of the project in external documentation, as everything needed is already available.
  7. 7. Configuring the Documentation• Development • Source Code Management • Collaboration Management • Notification Management • Continuous Integration • Distribution Management• Other Information • Developers • Contributors • Reporting • Licenses • Organisation
  8. 8. Setting up Continuous Integration• Download Apache Continuum • http://continuum.apache.org/download.html • Standalone bundled with Apache Tomcat • WAR for deployment on an Application Server• Unzip to destination tar zxvf apache-continuum-1.3.7-bin.tar.gz tar zxvf apache-continuum-1.3.7-bin.tar.gz• Start up Continuum ./continuum start ./continuum start• Set up project in Continuum • make the root pom.xml available via web • file protocol supported, but needs configuration
  9. 9. Some Continuum Features• Tool support: • Maven 1, 2 and 3 • ANT • Shell Scripts• Build Types: • Manual • Scheduled • Push with xmlrpc• Distributed Builds• Parallel Builds
  10. 10. Seeing Continuum in Action• Release Stages • Prepare for Release • Do the Release• Build Result • Artifacts deployed to the repository • If its public, users will have access to the POMs and the resources the POM files describe. • Site with: • Generated Test Results and Project JavaDoc, • Project information, • Dependency Information and many more... • Resources deployed to staging and/or production environment • (dependend on setup)
  11. 11. References• Apache • Maven: | http://maven.apache.org/ • Continuum: | http://continuum.apache.org/• Glassfish • Application Server | http://glassfish.java.net/• Prime Teknoloji • PrimeFaces: | http://www.primefaces.org/

  14. 14. 05/13/11 Maven From Scratch to Production by: Johan Mynhardt | Durban JUG Meeting | 12 May 2011|Welcome noteIntroduce yourselfWhy maven as a topic?
  15. 15. 05/13/11 What this is *not* • Ripe ground for flame-war • Argumenting that: • X is better than Y. • Y is better than X. • I can do this with X by making use of Z. • A session to convince youAvoid conflict and flame-wars :P
  16. 16. 05/13/11 Objectives • Set up a Maven project • Set up the CI environment with Apache Continuum • See everything in action!Quick overview of the entire presentations objective
  17. 17. 05/13/11 Project Technologies • Java EE 6 • Glassfish Application Server • EJB 3.1 • JSF 2.0 • PrimeFaces • Continuous Integration and Project Management (from development perspective) • Apache Continuum • Apache MavenQuick word on technologies used in the skeleton projectwhich took some time to set up
  18. 18. 05/13/11 Mavens Objectives• Making the build process easy• Providing a uniform build system• Providing quality project information• Providing guidelines for best practices development http://maven.apache.org/what-is-maven.html
  19. 19. 05/13/11 Setting up the Project: HelloWorld • Create the project root by running the following: ~/$ cd workspace ~/$ cd workspace ~/workspace$ mvn archetype:generate ~/workspace$ mvn archetype:generate -Dversion=1.0-SNAPSHOT -Dversion=1.0-SNAPSHOT -DgroupId=za.co.thumbtribe.djug -DgroupId=za.co.thumbtribe.djug -DartifactId=HelloWorld -DartifactId=HelloWorld • Select the number for the line matching (in this case 110): 110: remote -> maven-archetype-quickstart (An archetype which 110: remote -> maven-archetype-quickstart (An archetype which contains aasample Maven project.) contains sample Maven project.) • This will be the root of the project, containing the web, service and assemble sub-modules (multi-module project) • You now have the chance to add project-specific documentation and parameters to the pom.xml which you can later on, share with you developers. The convenience is that you dont need to keep track of every aspect of the project in external documentation, as everything needed is already available.The first steps in creating a maven project.Creating the child Modules are excluded.Child modules can be created using different project templates, war,ejb, ear, portlet etc.Steps excluded from setup: version control (subversion) ssh keys web config for project documentation
  20. 20. 05/13/11 Configuring the Documentation • Development • Source Code Management • Collaboration Management • Notification Management • Continuous Integration • Distribution Management • Other Information • Developers • Contributors • Reporting • Licenses • OrganisationJust covering the most parts needed for enabling the project to aproduction environment
  21. 21. 05/13/11 Setting up Continuous Integration • Download Apache Continuum • http://continuum.apache.org/download.html • Standalone bundled with Apache Tomcat • WAR for deployment on an Application Server • Unzip to destination tar zxvf apache-continuum-1.3.7-bin.tar.gz tar zxvf apache-continuum-1.3.7-bin.tar.gz • Start up Continuum ./continuum start ./continuum start • Set up project in Continuum • make the root pom.xml available via web • file protocol supported, but needs configurationThe standalone option is the easiestSetup in Glassfish requires JNDI resources being set up mail database logging config (working though)Depending on the project the default build flow is sufficient (for usingthe root POM and produce artifacts)
  22. 22. 05/13/11 Some Continuum Features • Tool support: • Maven 1, 2 and 3 • ANT • Shell Scripts • Build Types: • Manual • Scheduled • Push with xmlrpc • Distributed Builds • Parallel BuildsSCM support :CVS,Subversion,Clearcase,Perforce,Starteam,Visual Source Safe,CM Synergy,Bazaar,Mercurial
  23. 23. 05/13/11 Seeing Continuum in Action • Release Stages • Prepare for Release • Do the Release • Build Result • Artifacts deployed to the repository • If its public, users will have access to the POMs and the resources the POM files describe. • Site with: • Generated Test Results and Project JavaDoc, • Project information, • Dependency Information and many more... • Resources deployed to staging and/or production environment • (dependend on setup)Release preparation sees to it that most of the build issues are sortedout before a release. (issues not discovered in a normal build)Once preparation succeeds the build is ready for release.After the release build all the documentation and relevant informationwill be available in a web format which can be published, using the siteplugin.The site plugin enhances the developer experience in that for example,a new developer joins the team, he/she can be pointed to the projectsite which has all the required documentation.
