Introduction What is Maven? “Maven is a software management and comprehension tool based on the concept of Project Object Model (POM) which can manage project build, reporting, and documentation from a central piece of information” What is POM? “As a fundamental unit of work in Maven, POM is an XML file that contains information about project and configuration details used by Maven to build the project” History: Jakarta Turbine Project

Objectives and Characteristics of MAVEN Maven is more than just Build Tool Maven was built considering certain objectives Maven Provides:  Easy Build Process  Uniform Build System  Quality Project Information  Guidelines for Best Practices Development Achieved Characteristics:  Visibility  Reusability  Maintainability  Comprehensibility “Accumulator of Knowledge”

1.One level above ANT 2.Higher level of reusability between builds 3.Faster turn around time to set up a powerful build 4.Project website generation 5.Less maintenance 6.Greater momentum 7.Repository management 8. Automatic downloads ANT MAVEN Target build.xml Goal pom.xml Comparison with ANT

Main Features of MAVEN  Build-Tool  Dependency Management Tool  Documentation Tool

Overview of Simple Architecture

mvn archetype:generate -DgroupId = com.mycompany.app -DartifactId = my-app -DarchetypeArtifactId = maven-archetype-quickstart -DinteractiveMode = false Project Creation in MAVEN
