Maven Create and Build Artifacts

In Maven, you can create and build artifacts using the package phase of the build lifecycle. The package phase is responsible for taking the compiled code and other project resources and packaging them into a distributable format, such as a JAR (Java Archive), WAR (Web Application Archive), or other custom formats.

Here are the steps to create and build artifacts using Maven:

Configure the Build Output: In your project's pom.xml file, you need to configure the output of the build. This includes specifying the type of artifact you want to create (e.g., JAR, WAR) and any additional resources to include. You do this in the <build> section of your pom.xml:


<build>

    <finalName>my-artifact</finalName> <!-- Name of the artifact without the extension -->

    <plugins>

        <!-- Plugin configurations for creating the artifact -->

        <!-- For example, maven-jar-plugin or maven-war-plugin -->

    </plugins>

</build>

Depending on your project type and requirements, you would use different plugins (e.g., maven-jar-plugin for JAR projects or maven-war-plugin for web applications).

Run the Build: To create and build the artifact, you run the Maven build command. Open a command prompt or terminal in your project's directory and execute:

mvn clean package

clean: This goal removes the target directory, which contains the output of previous builds. It ensures that you start with a clean slate.

package: This goal is responsible for creating the artifact as specified in your project's pom.xml.

Review the Output: After running the Maven command, you'll find the built artifact in the target directory within your project's root directory. The name of the artifact is usually determined by the <finalName> configuration in your pom.xml file.

Deploy or Use the Artifact: Depending on your project's requirements, you can deploy the generated artifact to a repository, use it in other projects, or distribute it as needed.

Here's a more detailed example for creating a JAR artifact:

<project>

    <!-- ... -->

    <build>

        <finalName>my-jar-artifact</finalName>

        <plugins>

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-jar-plugin</artifactId>

                <version>3.2.0</version>

                <configuration>

                    <archive>

                        <manifest>

                            <mainClass>com.example.MainClass</mainClass>

                        </manifest>

                    </archive>

                </configuration>

            </plugin>

        </plugins>

    </build>

    <!-- ... -->

</project>

In this example, the maven-jar-plugin is configured to create a JAR artifact with a specified main class in the manifest file. When you run mvn clean package, it will generate a JAR file with the name my-jar-artifact.jar in the target directory.

Remember that Maven is highly configurable, and you can customize the build process, including artifact creation, to meet the specific needs of your project.

Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server

  Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server  Objective: The objective of this experiment is to set up a CI/CD pipeline for a web development project using Jenkins, Git, and webhooks, without the need for a Jenkinsfile. You will learn how to automatically build and deploy a web application to a local HTTP server whenever changes are pushed to the Git repository, using Jenkins' "Execute Shell" build step. Introduction: Continuous Integration and Continuous Deployment (CI/CD) is a critical practice in modern software development, allowing teams to automate the building, testing, and deployment of applications. This process ensures that software updates are consistently and reliably delivered to end-users, leading to improved development efficiency and product quality. In this context, this introduction sets the stage for an exploration of how to apply CI/CD principles specifically to web development using J
