What is Maven?

Apache Maven is an open-source project management platform tailored to the needs of software developers. Developed as an extensible, plugin-based architecture, Maven supports projects for different programming languages and provides guidance for building, testing, and releasing software projects. 

Maven’s main elements include –  

1. Maven Core: This is the core of Apache Maven, which contains the main Maven components, such as the Maven Project Builder and the Maven Plugin Framework.

2. Maven Plugins: This is a set of plugins used to extend Apache Maven’s functionality. These plugins enable developers to create custom builds, add support for various programming languages, and integrate with external tools and services.

3. Maven Repository: This is a repository of components that Apache Maven uses to build projects. These components are stored in a central repository and can be accessed by any Maven project.

4. Maven Archetypes: This is a set of project templates that developers can use to quickly create a Maven project.

5. Maven Lifecycle: This is a set of steps that define the order in which tasks are executed when building a Maven project.

Due to its flexible feature set, Apache Maven is a preferred tool among software developers seeking reliable project automation and high-level oversight.

Advantages of Maven

The primary reason for Maven’s existence is to simplify the build process. It is a powerful tool that can simplify the build process while providing developers with a wide range of options for managing dependencies and releases.

The advantages of Maven are –

1. Simplified dependency management: Maven is a great tool for managing a project’s dependencies. It allows developers to keep track of all external libraries used by the project and automatically downloads them from the remote Maven repositories.

2. Easy to maintain: Maven uses a standard directory layout and an XML-based configuration file (pom.xml) to manage the project build. This makes it easy to maintain and scale the project.

3. Reusability: Maven is based on the concept of reusable components and encourages developers to create and share their components. This allows developers to reuse code and speed up the development process.

4. Centralised repository: Maven provides access to a central repository of components known as the Maven Central Repository. This allows developers to easily find and download the components needed for their projects.

5. Automation: Maven allows developers to automate most project build tasks. This makes automating tasks such as running code analysis, generating reports, and running tests easier.

Disadvantages of Maven

One downside is that Maven dependencies can be tricky to manage. For example, if one dependency is incompatible with another, it can cause problems with the build. 

The disadvantages of Maven are – 

  • Maven can be slow to run, especially on large projects.

  • It is impossible to add a dependency if the Maven code for a preexisting dependent is not readily available.

  • Maven is not always easy to understand, particularly for beginners. Its complex configuration can be daunting, and it can take time to learn how to use all of its features effectively.

  • One has to be familiar with the Maven command-line interface or employ an IDE like NetBeans or Eclipse that integrates Maven.

Despite these drawbacks, Maven remains a popular tool for Java development. But it’s important to be aware of its potential downsides before using it on your next project.

Key features of Maven

Maven has many essential and beneficial features, which contribute significantly to its popularity. The following are some of Maven’s more notable attributes –

  • Integration with popular development tools such as Eclipse IDE and Jenkins CI server

  • Support for multiple build lifecycles (final product release or test build) and enforced standards that promote maintainable projects.

  • It is easily extendable, and plug-ins written in Java and other scripting languages are simple to create.

Maven – Use Cases

Maven is a build automation tool used primarily for Java projects and helps to manage a project’s build, reporting, and documentation from a central piece of information. Maven can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. It is based on the concept of a project object model (POM), which is an XML file containing information about the project, such as dependencies, build configuration, source directory structure, and more. 

Maven primarily aids in the download of dependencies, which are libraries or JAR files, for Java-based applications. Due to the possibility of various versions of individual packages, the tool aids in obtaining the appropriate JAR files for each project.

In addition, the tool aids in developing the proper project structure in servlets,  struts, etc., which is crucial for execution. Using the Maven command, one may request the execution of a lifecycle, which includes all of its build steps. Every construction phase in the given sequence is also run if one build phase is asked to be executed.

What is Jenkins?

Jenkins is an open-source automation server designed to help software development teams better manage complex projects. It combines technologies such as continuous integration, distributed builds, and version control with the ability to monitor web applications and deploy code changes quickly and easily. 

Jenkins is written using Java which makes it platform-independent, allowing it to be installed on Windows, Mac OS X, Linux, or Unix platforms without any compatibility issues. The user-friendly interface is well organized and allows developers to easily set up automated processes by creating pipelines or build flows and Jenkins development lifecycle

Jenkins vs Maven: What are the differences?

Programming Models

Maven is primarily configurable via XML-based Project Object Model (POM) files.

Jenkins acts as the integration server for easy configuration.

Learning Curve 

Maven follows a declarative configuration model, where the desired build configuration is simply specified in a file known as the “pom.xml” file. Maven has a collection of standard plugins which are easy to use for typical build operations such as code compilation, test execution, and package creation. Maven also has plenty of documentation and tools available.

Jenkins is a more feature-rich and versatile tool than Maven; hence it has a slightly steeper learning curve. It also features a robust plugin ecosystem via which you can enhance its functionality and integrate it with other tools. However, for inexperienced users, the sheer amount of capabilities and plugins available in Jenkins might be intimidating. Jenkins also has a large and active community, so there is a wealth of online documentation and tools to assist you in learning how to use it.


Maven is used for controlling dependencies and the lifecycle of software. It is also made to interact with plugins, which let users add extra tasks to the build, test, package, install and deploy processes that come standard.

Whereas, Jenkins is made specifically to implement Continuous Integration. It automatically pulls code from a repository, compiles and packages it, and uploads it to a server for testing. Jenkins can use Maven as a build tool.

Dependency Management

Prior to Maven, Java developers frequently had trouble figuring out why the log4j dependency wasn’t satisfied on the production server. Maven found a solution by ensuring linked library integrity while building Java applications consistently through various development stages.

Jenkins builds may be heavily parameterized, and it is simple to divide builds into many parts, such as compile, test, and package. Jenkins can simply modularize builds.

Integrate Jenkins and Maven

Jenkins typically uses Maven repositories when deploying objects to remote locations. For instance, Sonatype’s Nexus or JFrog’s Artifactory.

Java ecosystem

Jenkins may be used as a server on many different operating systems, most notably Linux but also Windows, macOS, and several Unix variations. It may be executed on Oracle JRE or OpenJDK and requires a Java 8 VM or above.

With just one archetype command, users of Maven can build the framework for an Android, Java EE MicroProfile, Jakarta EE, or Spring Boot application that is fully compatible.


Jenkins is compatible with a wide range of programming languages and build tools, including Maven. Jenkins provides a web-based user interface (UI) for configuring and managing build tasks. It also features a robust plugin ecosystem via which you can enhance its functionality and integrate it with other tools in your development workflow.

Maven uses a declarative approach, where you provide the desired build configuration in a file called the “pom.xml” file. Maven reads this file and uses it to create the project based on the parameters supplied. Maven offers a command-line interface (CLI) for running Maven commands, as well as an API for invoking Maven features programmatically.


Maven is highly effective in automating the build process for Java-based projects.

Jenkins can be used to effectively automate the build, testing, and deployment processes for various types of software projects.

How to Integrate Jenkins and Maven With Selenium?

Eclipse is an essential prerequisite in order to integrate Jenkins and Maven. To use m2eclispe, you need to download the plugins from the eclipse marketplace. To find Maven, go to the eclipse marketplace and search for it. The first plug-in that appears in the search results is the one you need to download.

How to create a Maven project – 

Step 1 – To start a project in Eclipse, go to File -> New Project -> Other, and then choose Maven -> Maven project. It will aid in the development of a new Maven project.

Step 2 – After clicking the Next button, you must enter the Artifact Id and Group Id. It will be special for your project since anybody may use them to clone it after it is uploaded to the GitHub repository. Your project’s name is represented by Group Id and its folder name by Artifact Id.

Step 3 – Select a separate template for the project.

Step 4 – Select ‘Maven quickstart template’.

Step 5 – After that, you will obtain a project with a two-folder structure with two directories, 

  • src/main/java
  • src/main/test

You may keep your tests and other files in the src/main/test and src/main/java folders, respectively.

Step 6 – Upon successful completion, a pom.xml will appear in your project’s structure. The Maven’s soul is POM. To download all dependencies and add them to the project structure, enter the pom.xml file and add the following code to it.

Step 7 – Go to the official Maven repository website and perform a jar-specific search for each jar file. Next, duplicate the dependent tag and include it in the pom.xml file.

Step 8 – You can then integrate the TestNG framework for testing by adding the TestNG dependency to your pom.xml file. You must create a new testng.xml file in the root directory of your project which contain the configurations for your TestNG tests.

Step 9 – You require a single plugin, Maven Surefire, to execute the test using Maven. You require the testng.xml plug-in to execute the test with TestNG. The code must be compiled using Maven compiler plugins as well. This plug-in will make sure that testing executes well.
