Create a New Maven Project from Command Prompt

In this guide, we will learn how to create a new Maven project using the Command Line Interface (CLI). Maven is a powerful build automation tool that simplifies project management, especially for Java projects. There are different ways to create a Maven project, including using an Integrated Development Environment (IDE) or the CLI. This article will focus on the CLI method.

Prerequisites

Before creating a Maven project, ensure the following prerequisites are met:

• Java Development Kit (JDK) Installed: Verify by running java -version in the command prompt.
• Maven Installed: Verify by running mvn -version in the command prompt. Ensure Maven is downloaded, extracted, and the PATH variable is set correctly.
• Verifying Maven Installation: To check if Maven is installed correctly, open a command prompt or terminal and run:

mvn -version

You should see output indicating the Maven version, Maven home, and the Java version being used.

Creating a Maven Project Using CLI

There are two ways to create a Maven project using the CLI:

1. Interactive Mode
2. Non-Interactive Mode.

Method 1: Interactive Mode

In interactive mode, Maven prompts you for input during the project creation process. Follow these steps:

• Open Command Prompt: Open your command prompt or terminal.
• Run the Archetype Command: Use the following command to start the interactive project creation process:

mvn archetype:generate

Maven will prompt you to select an archetype (template).

For a typical Java project, you can choose maven-archetype-quickstart. The ID for this archetype is usually 2158.

Provide Details: Maven will ask for the following details:

• Group ID: A unique identifier for your project (e.g., com.learn.maven).
• Artifact ID: The name of the final package (e.g., maven-artifact).
• Version: The version of the project (default is 1.0-SNAPSHOT).
• Confirm Details: Confirm the details and Maven will generate the project structure.

Change to the Directory which you stored Project:

cd maven-artifact

You can see the project using the

maven-artifact> ls

With the help of these command we can see the structure of the project in the command Prompt

maven-artifact> tree

Method 2: Non-Interactive Mode

In non-interactive mode, all details are provided in a single command, which automates the process without further input. Follow these steps:

Open Command Prompt: Open your command prompt or terminal.

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false

Run the Command with Parameters: Use the following command, replacing the placeholders with your desired values:

Maven will create the project without prompting for additional input.

With the help of these commands we will see the Structure of the project

maven-artifact> tree
