Maven Project Creation Guide: Simple and easy-to-understand steps to help you get started quickly

Maven is a powerful project management tool that can help developers manage project dependencies and build Projects, release projects, and a series of other tasks. For beginners, they may feel that Maven configuration is complicated and don't know where to start. This article will introduce how to use Maven to create a simple Java project, and gradually add code examples to help readers get started quickly.

Step 1: Install Maven

First, you need to install Maven on your system. You can visit the Maven official website (https://maven.apache.org) to download the latest version of Maven and install it according to the guidelines of the official documentation. After the installation is complete, you can open a command line window and enter the following command to check whether Maven is successfully installed:

mvn -v

If the Maven version information is displayed, the installation is successful.

Step 2: Create a Maven project

Next, let us start creating a simple Maven project. Open a command line window and execute the following command:

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

This command will use Maven's own quick start template to create a new Maven project. In this example, the project's groupId is com.example and artifactId is my-project. You can modify these two parameters according to your needs.

Step 3: Import the project into the IDE

Now, we have successfully created a Maven project. Next, you can import the project into your favorite integrated development environment (IDE), such as IntelliJ IDEA, Eclipse, etc. Import the project in the IDE and wait for the IDE to automatically import the dependencies required by the project.

Step 4: Write code

Next let’s add some code to the project. Create a new Java class in the src/main/java directory, such as HelloWorld.java, and then add the following code inside:

package com.example;

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, Maven!");
    }
}

Step 5: Build the project

Open a command line window in the project root directory and execute the following command to build the project:

mvn clean compile

This command will clean up the old compilation results and recompile the project. If everything goes well, you will see the compiled class file in the target directory.

Step 6: Run the project

Finally, let us run the project. Execute the following command in the project root directory:

mvn exec:java -Dexec.mainClass="com.example.HelloWorld"

You will see "Hello, Maven!" output on the console, which means that you have successfully created a simple Maven project and run it successfully.

Conclusion

Through the above steps, you have successfully created a simple Maven project and written the first simple Java program. I hope this article can help beginners get started with Maven quickly and better manage their projects. Happy programming!
