Features of Maven

Maven is a powerful project management and build automation tool in the software industry. developed by the Apache software foundation. It is primarily used for java based projects only now It can support other languages also for building the project. Maven tool provides a complete build life cycle to the development team to build a product following different build phases in the build process. Maven manages project build, dependencies, documentation, and other releases in a standard and consistent manner. Its primary goal is to simplify the build process by providing a uniform system that can manage project dependencies and deploy projects.

Maven Features

Maven provides a lot of features to make the build process easy while building the project. Below we provide those features with examples for your reference.

• Project Management and Comprehension Tool:
  • Consistency: Standardizes project structures and conventions.
  • Documentation: Automatically generates project documentation.
• Dependency Management:
  • Centralized Repository: Manages and downloads project dependencies from a central repository.
  • Transitive Dependencies: Automatically includes dependencies of dependencies.
• Build Automation:
  • Life cycle Management: Defines a set of build phases (e.g., compile, test, package).
  • Plugins: Extensible through a wide range of plugins for different build tasks.
• Reproducible Builds:
  • Project Object Model (POM): Uses a POM file to define project configurations, ensuring reproducible builds.
  • Profiles: Supports build profiles for different environments (e.g., development, testing, production).
• Integration with Development Tools:
  • IDE Integration: Supports integration with popular IDEs like Eclipse, IntelliJ IDEA, and NetBeans.
  • Continuous Integration: Easily integrates with CI tools like Jenkins, Bamboo, and Travis CI.
• Version Control: Versioning: Manages project versions and facilitates continuous delivery.

Maven Directory Structure:

Maven follows a standardized directory layout. A typical Maven project might look like this

pom.xml file:

Maven dependencies are configured in XML file of a Project. Below is a sample pom.xml file.

<project xmlns="https://maven.apache.org/POM/4.0.0" 
         xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="https://maven.apache.org/POM/4.0.0 
                             https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.example</groupId>
    <artifactId>my-app</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

Common Maven Commands:

Maven provides various commands to manage the project life cycle. Some of the common commands include:

• mvn clean: It cleans the project by removing its target directory.
• mvn compile: It compiles the source code.
• mvn test: It runs the tests.
• mvn package: It packages the compiled code into a JAR file.
• mvn install: It installs the package into the local repository.
