1. APACHE MAVEN Bhavana Sudharshan Jaydeep Patel

2. 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

3. 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”

4. 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

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

6. Overview of Simple Architecture

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

8.  POM  source tree for your application's sources  source tree for your test sources Contents of the Created Project

9. 4.0.0 com.mycompany.app my-app jar 1.0-SNAPSHOT Maven Quick Start Archetype http://maven.apache.org junit 4.8.2 test POM.XML

10. BUILD.XML

11. Project Object Model (POM) Metadata: Location of Directories, Developers/Contributors, Dependencies, Repositories Dependencies (Transitive Dependencies), Inheritance, and Aggregation Key Elements  Project  Model Version  Group ID  Packaging  Artifact ID  Version  Name  URL  Description

12. src/main/javaApplication/Library sources src/main/resourcesApplication/Library resources src/main/filtersResource filter files src/main/assemblyAssembly descriptors src/main/configConfiguration files src/main/scriptsApplication/Library scripts src/main/webappWeb application sources src/test/javaTest sources src/test/resourcesTest resources src/test/filtersTest resource filter files src/siteSite LICENSE.txtProject's license NOTICE.txtNotices and attributions required by libraries that the project depends on README.txtProject's readme Standard Directory Layout

13. Artifact Repository (Local) Build C Artifact Repositories (Remote) Look for A & B com.acme B [1.0,) compile « Any Version After 1.0 » Dependency Management

15. Allows automatically inclusion of libraries Avoids the need to discover and specify the required libraries that your own Transitive Dependencies
