Maven is a build automation tool that is mostly used for Java applications. It offers a uniform method for developing, testing, and packaging Java programmes, as well as managing project dependencies.
Maven builds projects in a declarative manner, with the build process defined in a configuration file called pom.xml.
This file provides details on the project, its dependencies, and the many stages of the build process, such as compilation, testing, packaging, and deployment.
Maven's ability to manage project dependencies automatically is one of its primary advantages.
Maven can download and maintain dependencies without the need for user intervention from a central repository, such as the Maven Central Repository.
This simplifies the management of complex Java projects with several dependencies.

Maven organizes the build process into a series of phases, which are executed in a predefined sequence. Each phase corresponds to a specific stage of the build process and performs a specific set of tasks. The phases of Maven are:
Validate: This phase validates that the project is correct and all necessary information is available.
Compile: This phase compiles the project's source code into executable classes.
Test: This phase runs unit tests for the project.
Package: This phase packages the compiled code and any necessary resources into a distributable format, such as a JAR or WAR file.
Verify: This phase performs any checks to verify that the package is valid and meets quality standards.
Install: This phase installs the packaged code and any necessary artifacts into the local repository for use in other projects on the same machine.
Deploy: This phase deploys the packaged code and any necessary artifacts to a remote repository or server, such as a production server.
There are also two additional lifecycle phases that can be used to customize the build process:
1.Clean: This phase cleans the project by deleting any generated files, such as compiled classes or packaged files.
2.Site: This phase generates the project's website documentation, such as project reports and user guides.
