======
Maven
======

=> It is free and open source s/w.

=> It is developed by Apache org.

=> It is developed using java lang.

=> It is used as build tool for java projects.

=> Maven is used to automate "java projects build process".

===========================
What we can do using Maven
============================

1) We can create java projects skelton/structure.

2) We can download required libraries (jars)

	Ex: spring, boot, hibernate, junit, poi, itext...

3) We can compile project source code

4) We can execute project unit test cases 
   (junits)	

5) We can package application as jar or war file for execution.

==================
Maven Terminology
==================

Archetype : Represents type of project

		quick-start : console app

		web-app : web application

groupId : Represents company name

	Ex : com.tcs
		 com.ibm
		 in.ashokit


ArtifactId : Represents project name

Version : Represents project version
	
		SNAPSHOT : under development

		RELEASE : Delivered to client		 	


Dependencies : Represents libraries required for project

	Ex : spring, spring-boot, hibernate, junit..


Maven Repositories : Represents the location of maven dependencies

		1) Central (public)
		2) Remote (private -> nexus/jfrog)
		3) Local (.m2)

Maven Goals : Used to perform project build process.		

	compile : convert .java files to .class files

	test : execute junits

	package : generate jar or war

	clean : delete .class files


=============
Maven Setup
=============

@@ Ref Video : https://www.youtube.com/watch?v=hV1OWzYpzxo

1) Download and install jdk s/w

2) Setup JAVA_HOME and Java Path in env variables

3) Download Maven software from apache website

4) Setup MAVEN_HOME and maven path in env variables

5) Verify maven setup using cmd

		mvn -version
==================================================


============================
Create Maven Project in CLI
============================

=> Open CmD and execute below command to create maven project

mvn archetype:generate -DgroupId=in.ashokit -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.5 -DinteractiveMode=false

=> We can see below folder structure in the maven project

		My-App
			- src/main/java   (source code .java files)
			- src/main/resources (config files)
			- src/test/java (junit classes)
			- src/test/resources (config files for testing)
			- Maven Dependencies (jars)
			- pom.xml (project object model)

=> Go inside maven project and execute maven goals

		cd my-app

		mvn compile
		mvn test
		mvn package
		mvn clean package			


=> Byte code will be generated in project "target" directory.		

=> We can add maven dependencies in "pom.xml" file.

=> We can find maven dependencies in below website

		URL : www.mvnrepository.com
