What is Apache Maven?

Apache Maven is a project management and comprehension tool that provides developers a complete build lifecycle framework. Development team can automate the project's build infrastructure in almost no time as Maven uses a standard directory layout and a default build lifecycle.

Primary Objectives of Apache Maven

The primary goal of Maven is to provide developer with the following −

  • A comprehensive model for projects, which is reusable, maintainable, and easier to comprehend.

  • Plugins or tools that interact with this declarative model.

This Maven tutorial is based on the latest Apache Maven 3.9.11 version.

Features of Maven

  • Model-based builds − Maven is able to build any number of projects into predefined output types such as jar, war, metadata.

  • Coherent site of project information − Using the same metadata as per the build process, maven is able to generate a website and a PDF including complete documentation.

  • Release management and distribution publication − Without additional configuration, maven will integrate with your source control system such as CVS and manages the release of a project.

  • Backward Compatibility − You can easily port the multiple modules of a project into Maven 3 from older versions of Maven. It can support the older versions also.

  • Automatic parent versioning − No need to specify the parent in the sub module for maintenance.

  • Parallel builds − It analyzes the project dependency graph and enables you to build schedule modules in parallel. Using this, you can achieve the performance improvements of 20-50%.

  • Better Error and Integrity Reporting − Maven improved error reporting, and it provides you with a link to the Maven wiki page where you will get full description of the error.

Frequently Asked Questions about Maven

There are some very Frequently Asked Questions(FAQ) about Maven, this section tries to answer them briefly.

Normally a deployment process consists of following steps −

  • Check-in the code from all projects in progress into the SVN or source code repository and tag it.

  • Download the complete source code from SVN.

  • Build the application.

  • Store the build output either WAR or EAR file to a common network location.

  • Get the file from network and deploy the file to the production site.

  • Updated the documentation with date and updated version number of the application.

Maven is a project management and comprehension tool. Maven provides developers a complete build lifecycle framework. Development team can automate the project's build infrastructure in almost no time as Maven uses a standard directory layout and a default build lifecycle.

Maven uses Convention over Configuration which means developers are not required to create build process themselves. Developers do not have to mention each and every configuration details.

Maven provides developers ways to manage following −

  • Builds
  • Documentation
  • Reporting
  • Dependencies
  • SCMs

POM stands for Project Object Model. It is fundamental Unit of Work in Maven. It is an XML file. It always resides in the base directory of the project as pom.xml. It contains information about the project and various configuration details used by Maven to build the project(s).

POM contains the some of the following configuration information −

  • project dependencies
  • plugins
  • goals
  • build profiles
  • project version
  • developers
  • mailing list

An artifact is a file, usually a JAR that gets deployed to a Maven repository. A Maven build produces one or more artifacts, such as a compiled JAR and a "sources" JAR.

Each artifact has a group ID (usually a reversed domain name, like com.example.foo), an artifact ID (just a name), and a version string. The three together uniquely identify the artifact. A project's dependencies are specified as artifacts.
