Wonderful World of Maven
8 likes1,016 views
Maven is a project management and build tool that promotes convention over configuration using a hierarchical Project Object Model (POM). It can build Flex projects by generating artifacts like SWF and SWC files. The flexmojos plugin supports Flex, AIR, and AS3 projects by adding goals for tasks like compiling, testing, documentation, and optimization. To set up a Flex project with Maven and flexmojos, developers use an archetype to generate the project structure, configure repositories and dependencies, then build and debug the project using Maven goals and phases.
![Eg. the Flex framework dependency
groupId: com.adobe.flex.framework
artifactId: flex-framework
version: 4.5.1.21328
packaging: pom
Artifacts are filed away in repositories using:
/[groupId]/[artifactId]/[version]/[artifactId]-[version].[ext]](https://image.slidesharecdn.com/wonderful-world-of-maven-111003181603-phpapp02/85/Wonderful-World-of-Maven-11-320.jpg)
![A phase is a collection of goals. [M:M]](https://image.slidesharecdn.com/wonderful-world-of-maven-111003181603-phpapp02/85/Wonderful-World-of-Maven-14-320.jpg)
Wonderful World of Maven
- 1. MAV EN the Wonderful World of Maven and Flexmojos
- 2. 1. definition
- 3. More than just a build tool - Maven is project management.
- 4. It’s built in Java and lives under the Apache umbrella, (∴ still new to Flex developers)
- 5. it promotes convention over configuration
- 6. and, it is hierarchical.
- 7. Everything builds via a Project Object Model (POM): aka the blueprint.
- 8. A build generates one or more artifacts. (Typically one artifact per POM)
- 9. Artifacts are classified by groupId, artifactId, packaging (type) and version.
- 10. Versions stamped with SNAPSHOT are treated as such.
- 11. Eg. the Flex framework dependency groupId: com.adobe.flex.framework artifactId: flex-framework version: 4.5.1.21328 packaging: pom Artifacts are filed away in repositories using: /[groupId]/[artifactId]/[version]/[artifactId]-[version].[ext]
- 12. 2. building
- 13. A goal is a single action.
- 14. A phase is a collection of goals. [M:M]
- 15. A lifecycle is a sequence of phases (upto & including).
- 16. The odd couple: clean & install. > mvn clean install
- 17. The packaging (eg. SWF, SWC, JAR) typically defines the goals within each phase.
- 18. In general, the default lifecycle involves the following phases: ■ validate ■ compile ■ test ■ package ■ integration-test ■ verify ■ install ■ deploy
- 19. In addition, plugins provide goals and can bind them to phases. eg. > mvn compiler:compile compiler:testCompile
- 20. Plugins include compiler, install, scm, release, javadoc, eclipse, flexmojos, etc.
- 21. 3. dependencies
- 22. Dependencies are hosted in repositories.
- 23. Each install of Maven has a repository. (~/.m2 is your new best friend).
- 24. In order to add new dependencies to your repository, you can simply > mvn install:install-file
- 25. You add references to repositories either in your POM or in your settings.xml file.
- 26. When building, if a dependency is missing, Maven will try to download it from an upstream repository.
- 27. As a last resort, it will check Maven Central (search.maven.org).
- 28. How are dependencies shared across repositories? Nexus.
- 29. Nexus allows an organisation to share artifacts both internally and externally.
- 30. It has out-of-the-box support for both snapshot and release repositories.
- 31. So, what about dependencies on teh internez?
- 32. Nexus will proxy to other external Nexus repositories.
- 33. If the dependency isn’t hosted - there’s a 3rd Party repo that you can upload into.
- 34. 4. the flexmojos plugin
- 35. Out of the box, Flexmojos supports: ★ Flex 3/4, AIR and AS3 projects ★ Unit tests & code coverage reports ★ ASDoc generation ★ RSL and runtime module support ★ Goal to create IDE project ★ SWF optimization ★ Archetypes to get started ★ WAR bundling & deployment
- 36. Goals bound to the default SWF and SWC lifecycles
- 37. function preinit() { download(maven, ‘3.0.3’).install().append(system.path); download(flashplayer-standalone, ‘10.3’).install().append(system.path); flashbuilder.plugins.add(m2eclipse); } First you have to setup your environment.
- 38. #1. Use a Flexmojos archetype to get started. mvn archetype:generate -DarchetypeRepository=http://repository.sonatype.com/content/groups/flexgroup -DarchetypeGroupId=org.sonatype.flexmojos -DarchetypeArtifactId=flexmojos-archetypes-application -DarchetypeVersion=4.0-RC2
- 39. #2. Add repo location of Flex SDK. http://repository.sonatype.org/content/groups/flexgroup
- 40. #3. Build. mvn clean install
- 41. #4. Import Maven project into Flashbuilder
- 42. #5. Check project settings - source folders, compiler and config.
- 43. #6. Setup Maven build and debug as required.
- 44. Tip: Only check in /src and your POM - everything else can be generated.
- 45. 5. fin
- 46. Don’t skim the conventions. Learn the basics and save yourself hours of endless frustration.
