Maven Commands Cheat Sheet

Introduction

Maven is a powerful build automation tool used primarily for Java projects. It simplifies the build process, dependency management, and project configuration through the use of a standardized project object model (POM). Understanding the essential Maven commands can help you manage your project builds efficiently. This cheat sheet provides a quick reference to the most commonly used Maven commands and plugins.

What is Maven?

Maven is a build automation tool from the Apache Software Foundation, designed to simplify the process of managing project builds, dependencies, and documentation. Maven uses a Project Object Model (POM) file to define project structure, dependencies, and build configurations, making it easier to manage large and complex projects.

mvn archetype:generate -DgroupId=org.yourcompany.project -DartifactId=application Creates a new Maven project from an archetype.
mvn archetype:generate -DgroupId=org.yourcompany.project -DartifactId=application -DarchetypeArtifactId=maven-archetype-webapp Creates a new Maven web project from an archetype.
mvn clean Cleans the project by deleting the target directory.
mvn validate Validates the project structure and checks for any missing or incorrect dependencies.
mvn compile Compiles the source code of the project.
mvn test Runs the unit tests using a suitable testing framework.
mvn package Packages the compiled code into a distributable format, such as a JAR or WAR file.
