Building Java Projects Made Easy with Maven

 Maven:

•  Maven is a project management tool or software build tool or dependency management tool.
•  It is used for project build or dependencies.

Maven addresses two aspects:

 1. It describes how software is built.

 2. It describes the software dependencies.

• In Maven execution starts from the pom.xml file, it reads the POM.xml file and starts execution.

Uses of Maven:

•  It is used to build the software application, manage your dependencies, run your tests, and create reports.

Maven Structure:

 src/main/java

 src/main/resources

 src/test/java

 src/test/resources

 JRE System library

 Maven Dependencies

 src

 target

 pom.xml

pom.xml: (Project Object Model)

•  A Project Object Model or POM is the fundamental unit of work in Maven.
•  It is an XML file that contains information about the project and configuration details used by Maven to build the project.
•  It contains default values for most projects.
