Maven Overview Part 1 Denver JBOSS User ’ s Group January 2006 Scott Ryan Soaring Eagle L.L.C

Agenda
Why Maven?
Maven 101
Deployments with Maven
Maven integrations
Maven in the enterprise
Maven 1.0 versus 2.0
Demo
Soaring Eagle L.L.C

Analogy: How to develop an application? Soaring Eagle L.L.C My Application Frameworks Solution 1 My Application Solution 2 Container E.g. Application Server, Eclipse RCP, Net beans, etc API Services

Maven Objectives
Make the build process easy
Provide a uniform build system
Provide quality project information
Provide guidelines for best practices development
Allow transparent migration to new features
Soaring Eagle L.L.C

How to develop a build? Soaring Eagle L.L.C My Build Ant tasks Solution 1: Ant My Build Solution 2: Maven Maven (Container) Task calls Goals/Plug-ins « Maven is a build container »

Advantages of a Container Approach
Ability to reuse existing services
More than 100 existing Maven plug-ins (jar, cactus, clover, JIRA, site, dashboard, etc)
Easy to get started
Just need to configure and extend
Ability to benefit from new services simply by upgrading
Well-defined and shared structure/architecture
Soaring Eagle L.L.C

Advantages (Cont.)
Easier to maintain
Knowledgeable resources on the market
Well-defined structure
It makes sense to use a custom approach when flexibility is a must
This is not usually the case for builds

Current Versions
Maven 1
1.0.2 and 1.1-beta-2
maven command
Cut your teeth here and don ’ t worry about the beta label
Maven 2
2.0.1
mvn command
Can run side by side
Soaring Eagle L.L.C

Maven 101
Maven in 3 concepts:
POM (Project Object Model)
Plug-ins
Made of Goals = Actions
Repositories
Maven files (1.0)
project.xml
POM (Project Object Model)
maven.xml
Custom goals in Jelly
Goal, pre-Goal, post-Goal
project.properties
Runtime Configuration
build.properties

Value of a repository structure
Multiple Levels including environment specific (Dev, QA, Stage, Production)
Contains Versioned resources
Can control external library usage
Logical Organization of artifacts
Speeds builds using build once philosophy
Provides audit trail (record of build components)
Multilevel security
Soaring Eagle L.L.C

Maven Repositories Soaring Eagle L.L.C Maven core Remote Repository Web Server Local Repository project.xml (POM) 1 2 3 4 JVM 1 JVM 2 HTTP Get dependencies Checks if artifact exists in local repository. Download artifact Save artifact in local repository

Agenda
Why Maven?
Maven 101
Maven integrations
Demo
Soaring Eagle L.L.C

It ’ s still an unconsolidated area in (1.0)
Several plug-ins can be used
Artifact
SCM
Release
Dist
Site
Artifact generation plugins
Weblogic Plugin
In the future, to be replaced by Maven-Wagon and Maven-SCM
Soaring Eagle L.L.C

Release Management
Integrates with multiple Source code control systems.
Integrates with JIRA for release management
Allows for separation of concerns to support SOX initiatives.
Provides audit trail
Easy automation for no touch build and deployment
Reduces possibility of errors

Agenda
Why Maven?
Maven 101
Maven integrations
Demo
Soaring Eagle L.L.C

Maven integrations
IDE
Mevenide (Eclipse + Net beans + JBuilder)
Goal launcher
Search in well known Maven remote repos
POM editor
POM validation
POM/IDE synchronizer
Jelly editor
Maven builder nature (know which goals should be run when resources change)
Continuous builds
Cruise Control, Damage Control, Gump, Continuum
Future (m2): all Java
Easier integration
Talks about a Maven IDE

Team organization
Build Coach
The new type of Quality Manager?
Overall build responsibility
Schedule build improvements in project iterations
Defines quality strategies
E.g. Clover: start at 0% and at each iteration increase to level attained. Fail build if below.
Manages build improvements
Improve build-awareness
Every day commit by team
Run local build before commits
Gather build requirements from teams
What checkstyle rules do we want to apply?
Is the build running fast enough?
Analyze reasons for build failures
Build leaders in each team
Analyze build failures
Ensure build failure are given top priority and get fixed ASAP
Coaches team to be build-aware and listen to team
Soaring Eagle L.L.C Project Manager Build Coach Team N Build Leader

Demo time
Create a new project using the archetype plugin
Create a matching Eclipse project using the eclipse plugin
Create a jar and run the unit tests (jar/test plug-ins)
Create the developer ’ s website including reports
Prepare a release
Produce a Release
