📦 Maven

Apache Maven

Apache Maven is a powerful build automation tool used primarily for Java projects. It helps manage dependencies, build processes, and project structures efficiently. This guide will help you install Maven on your system.

Step 1: Download Maven

Go to the official Apache Maven Download page.
Download the latest binary zip file for your operating system (Windows, macOS, or Linux).
Extract the downloaded file to a directory of your choice (e.g., C:\Program Files\Apache\Maven on Windows or /opt/maven on Linux/macOS).

Step 2: Set Up Environment Variables

On Windows:

Open System Properties > Advanced > Environment Variables.
Add a new system variable:
- Variable name: MAVEN_HOME
- Variable value: Path to the extracted Maven directory (e.g., C:\Program Files\Apache\Maven)
Edit the Path variable and add %MAVEN_HOME%\bin.

On macOS and Linux:

Open the terminal and edit your shell profile file:
```
nano ~/.bashrc  # or ~/.zshrc
```

Add the following lines:

export MAVEN_HOME=/opt/maven
export PATH=$MAVEN_HOME/bin:$PATH

Apply changes:
```
source ~/.bashrc
```

Step 3: Verify Installation

To check if Maven is installed correctly, run the following command:

mvn -version

If installed successfully, you should see output similar to:

Apache Maven 3.x.x (latest version)
Maven home: /path/to/maven
Java version: 1.8.0_xxx, vendor: Oracle Corporation

Step 4: Run a Sample Maven Project

Open a terminal or command prompt and create a new Maven project:

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

Navigate into the project directory:
```
cd my-app
```
Build the project:
```
mvn package
```

Run the application:

java -cp target/my-app-1.0-SNAPSHOT.jar com.example.App

Conclusion

You have successfully installed Maven on your system! You can now use it to manage dependencies and build Java projects efficiently.
