What is Maven? Uses, Features, Benefits & Case Studies

Maven is a software project management solution that also provides an overview and visualisation of the project to help with learning and exploration. Software Process Management is accomplished through organising the project's development, offering a standardised and streamlined method of specifying and maintaining the project's resources, files, and requirements, and sharing the project's resulting artefacts.

Generating information regarding the project, managing the reports, and documenting the initiative all contribute to visualising the project.

Maven in DevOps should be utilised in these scenarios:

If the initiative has a significant number of dependencies.
If the dependencies' version needs to be upgraded frequently.
The task involves rapid documentation, compilation, and bundling of source code as JAR or ZIP files.

Why should we make use of the Maven system?

If you're an Eclipse user, there's no reason why you need to use Maven for developing projects. The ID environment that eclipse provides is all you need to get your project fully operational. In contrast to Maven, it does not build your code. If you're working on a Java project requiring you to use third-party libraries, you'll need to ensure you have the necessary dependencies in place. Dependencies are nothing more than the library or jar files.

The reason for its application:

It is a development tool that creates libraries similar to jar files. However, the code is organised into a library that may be distributed.
Because it is a dependency management solution, obtaining and managing dependencies is different from how we normally handle them.
Its project management capabilities are stronger than other tools. Maven can save information about the software, such as the name and version number. So, it gave a general idea of what the initiative was about.
Unlike other fields, it has a standardised method for developing software. Maven ensures that each project maintains consistency, which boosts productivity.
Since it is a command-line platform, its instructions must be sent through the command prompt. To implement a system, it would do a set of tasks. Moreover, several IDEs, such as Eclipse, might be used to develop applications with Maven.

Features of Maven:

As modifications are made to Maven, clients may quickly update their configurations to take advantage of these changes. This is definite to both the initiatives and the individuals who use Maven.

The following are some of the Maven's most important features:

Simple project configuration that adheres to best principles - The process of building a robust project can be finished in a moment.
Consistent application throughout all initiatives - Since the tools are the same for all projects, it is easier and doesn't take any effort to show new programmers how to use them.
Advanced interdependence administration - Dependencies are easy to set up. These can be automatically updated by only using the most current versions. Program dependencies can be closed or transitive – they have additional requirements and need to be included in the solution throughout development. In addition, we may now describe compile-time, testing, environment-specific, and production-time variables.
Able to effortlessly manage many tasks simultaneously - A growing library and metadata repository ready to use right out of the box and also deals with the top Open Source projects to make their most recent releases instantly available.
Extensible - Maven enables you to extend the basic maven process with custom plugins, including the ability to develop plugins or programming language relatively easily.
Model-based development - Most of the time, no scripting is required for Maven to generate predefined output types like JARs and WARs or distributions from any number of projects. Instantaneous access to newly added functionalities with minimal or no additional configuration requirements
Site providing project information that is well-organised - Using the same metadata as the construction process, Maven may generate a website or PDF and offer regular reporting on the project's development status, along with any documentation you desire.
Publication of the release and control of its distribution - Maven integrates with your sources control system (like Git) and manages project releases based on tags. It can also send this information to a place where other projects can use it. Maven has the capability of publishing individual outputs like JAR files, archives that contain other documentation, and source distributions.
The management of dependencies – Maven, promotes the usage of a centralised repository for JARs and some other dependencies. Maven has a way of downloading JARs from a central repository that may be used to build your project. Users of Maven are given the ability to reuse JARs across several projects, and collaboration between projects is encouraged to guarantee that concerns with backward compatibility are resolved. Outside of Maven, you can use tasks to handle and deploy.

How to use Maven?

To configure Maven in the Programming language, you must require the pom.xml file containing the Project Object-oriented approach.
POM contains all Maven-related configuration settings. A pom.xml file's plugins section can be used to configure and modify plugins. Plugin developers don't need to know the specifics of every plugin they use.
When users start working on a Maven project, it gives them a default configuration, so they don't have to add each configuration to pom.xml.

Procedures/processes involved in developing the project:

Contribute to the creation of the application by writing or adding code and then processing this into the source code.
Modify the pom.XML and plugin details in the configuration.
Design and develop the application
Create a WAR or EAR file from the output of the build process and store it locally or on a server.
Obtain the file from the server, and then send it to the production site, whichever is appropriate.
The client site Date and revised version number have been added to the application document.
Design and write a report under the specified application or requirement.

Working with the Maven tool:

It features many components that interact with each other to assist users in developing the projects. A command is put into the command line at first.

The pom.xml file would be examined by the install command to learn about the project and its build specifications. The sections of the data that it reads include the project's details, and this is where we would discover a way of searching for the Artifacts that the build would also form.

Additionally, the requirements and plugins will be examined. Plugins are required to create the Artifact since they modify the code, while dependencies are project libraries.

Maven's dependency management facilitates the acquisition of plugins and dependencies. Dependency management works this way: First, pom files are examined for plugins and dependencies, and then specific repositories are accessed.

What is Maven in DevOps?

Maven is a well-known open-source tool created to simultaneously build, manage, and deploy multiple projects for improved project management. It has a development process comparable to that of ANT. However, it is more innovative than ANT. SCMs builds, and documentation is all taken care of by Maven, as also the distribution of releases. Maven loads packages from Maven Central.

It makes the process of developing a project easier by giving a consistent approach to the process of developing and maintaining a project. So, it's needed in many different fields, and as we've already seen, Maven is used by employees everywhere, from software applications to IT.

Case study of Maven

Maven can automatically add all required dependencies for a project by reading the pom file.
Maven makes it easy to build a project to the jar, war, or any other format that suits the user's needs.
With Maven, starting work in different contexts is easy, and you don't have to worry about injecting dependencies, building, processing, etc.
It's easy to add a new dependency. The dependencies code only has to be written in the POM file.
