Maven is a project management tool that provides the developer with a complete build lifecycle framework. Usually, a typical Maven project is conceived by an Apache Software Foundation where you will see that it was previously a component of the Jakarta project. Several reasons contribute to the popularity quotient. These factors are seamless dependency management, complete environment support (plugins, etc.), and the much-needed build life cycle support. DevOps comprise many phases and Maven is a tool that helps in the build phase of the DevOps lifecycle.
We have developed a list of Maven interview questions and answers for our readers. This list of interview questions and answers is surely going to give you a good head start for your Maven interview.
Ans: POM is the acronym that is used for Project Object Model. A POM is the important unit of the Work module in Maven. POM is an XML file that is always located in the base directory of the given project. It can be found with the extension of pom.xml. It contains the complete information that is available about the project along with the various configuration details used by Maven to build the project(s).

Ans: A Maven artifact is a file that is generally like a JAR that directly gets organized on to a repository of Maven. The usual build in Maven generates one or more artifacts at one given time.
Every Maven artifact comes with a unique group ID, the artifacts' ID, and a version string. These three components collectively form the unique ID that is used to identify the Maven artifact.
Ans: There are three kinds of build phase lifecycles in Maven, they are −
clean: cleans up the Maven artifacts that were created by the previous builds.
default (or build): This lifecycle is generally used to build the given application.
site: helps to generate site documentation that is needed for the project.
Ans: The different phases that comprise a Maven Build lifecycle are−
Ans : Here is a list of the primary features of Maven:
Ans:
Ans:
Ans: A goal speaks to a particular assignment that adds to the structure and overseeing of a project venture. It will undoubtedly at least zero form stages. An objective that isn't bound to any form stage could be executed outside of the assemble lifecycle by invocating it straightforwardly.
Ans: A Build profile is a lot of setup values that can be utilized to set or abrogate default estimations of Maven assemble. Utilizing a form profile, you can modify work for various situations, for example, Production and the Development conditions.
Ans: The order of inheritance in Maven is-
Ans: Dependency with scope framework is constantly accessible and doesn't gaze upward in the storehouse, they are generally used to educate Maven concerning conditions that are given by the JDK or the VM. Along these lines, framework conditions are particularly helpful for settling conditions on ancient rarities that JDK typically gives.
Ans: You can check any transitive dependency as discretionary utilizing the "discretionary" component. For instance, X relies on Y and Y relies on Z. Presently Y stamped Z as discretionary. At that point, X won't use Z.
Ans: You can bar any transitive reliance utilizing the "exclusion" component. Assume if X relies on Y and Y relies on Z, at that point X can be stamped Z as barred.
Ans: Central Repository is the Repository given by the Maven people group. It contains countless usually utilized libraries. At the point when Maven doesn't discover any reliance in neighborhood vault, it begins looking in focal archive utilizing the following URL: http://repo1.maven.org/maven2/.
Whereas now and then, Maven doesn't discover a referenced reliance in focal store too then it stops the fabricate procedure and yields mistake message to support. To forestall such circumstances, Maven gives an idea of Remote Repository which is an engineers' custom store containing required libraries or other undertaking containers.
Ans: Maven archetypes are formats to make an assortment of Java venture structures, including web applications explicit to a holder, for example, Wildfly. At the end of the day, it is an instrument that makes the stuff you manufacture the task on.
Ans: You can find dependency in the neighborhood vault arrangement of your product. Now and again, it is hard to find or distinguish in the neighborhood archive. Along these lines, I can discover or glance in the focal archive framework and on the off chance that it shows the reliance missing, at that point one can glance in the remote storehouse to discover the reliance. On the off chance that it despite everything shows something very similar over and over, at that point the framework will show mistake in finding the conditions. Also, on the off chance that the conditions are found in the nearby storehouse, at that point it will be naturally downloaded in the focal vault for some time later.
Ans: There is more than thousand Java venture as there are formats, skeleton gave to you by Maven with the goal that you don't need to recall a fundamental design detail or an essential arrangement of that specific kind of task which Maven is going to offer it to you. It incorporates models like fundamental Java venture, Spring Project, Spring MVC, Spring Web Flow, and Spring Boot.
Ans: Maven figures out what rendition of reliance are to be utilized when various forms of a curio are experienced. On the off chance that two reliance adaptations are at a similar profundity in the reliance tree, the primary proclaimed reliance will be utilized. This is called reliance intercession.
If you have any doubts on Maven, then get them clarified from Maven Industry experts on our Maven community
Ans: To reference a property characterized in your pom.xml, the property name utilizes the names of the XML components that characterize the worth, with "pom" being permitted as a pseudonym for the venture (root) component.
So ${pom.name} alludes to the name of the undertaking, ${pom.version} alludes to the variant of the task, ${pom.build.finalName} alludes to the last name of the document made when the fabricated venture is bundled, and so forth.
Ans: Mojo is a Maven plain Old Java Object. Every mojo is an executable goal in Maven, and a module is the dissemination of at least one or more related mojo elements.
Ans: Ant is just a tool compartment while Maven is about the use of examples to accomplish a foundation that shows the attributes of perceivability, reusability, practicality, and comprehensibility. It isn't right to consider Maven as a build tool and only trade for Ant.
Ans: The elements that are minimally required are-
Ans: If you want to produce execution debug output you should call Maven with the X parameter or the e parameter.
Ans: If you want to run test classes in Maven, you will firstly need a secure sure-fire plugin, then you need to properly check as well as configure your necessary settings in the setting.xml extension and the pom.xml extension for a property named "test."

Ans: We can do that by simply utilizing a subset of the existing elements in the POM in the question itself.
Ans: We use the Maven plugins to
Ans: All POMs are inherited from a parent regardless of expressly characterized or not. This base POM is called Super POM and it contains values that are acquired naturally.
Ans: We can do that by giving the following command

Ans. Maven is an open-source project management tool based on Java that is useful for developing, publishing, deploying, and managing multiple projects. It helps to automate the project's build infrastructure, making it easier for the development team. Moreover, it simplifies the developer's daily work and helps manage projects based on Java.
Ans. The following are the aspects that Maven offers to developers to manage:-
Ans. Build tool helps the entire building process, and it covers many purposes. It helps in producing and compiling source code, builds documentation using the source code, helps to package the compiled code into a JAR file, and installs the packaged code to a server, local or central repository.
Ans. The repository in Maven refers to a place or a directory that contains all the JAR files, plugins, and other project-based artefacts. In other words, it is a storage folder that saves all the projects and files like JAR, WAR, etc.
Maven has three types of repositories like Local, Central, and Remote Repository.
Ans. Below are the two types of plugins available in Maven:-
Reporting Plugin - The reporting plugins are performed in the site production and are configured within the element
Ans. Dependency management is the concept used by Maven in the Maven Repositories. If there is an absence of dependency in any remote and central repositories, then External Dependency is used by Maven.
Ans. Maven offers a settings.xml file as a settings file that includes various elements to define values that help to configure Maven execution differently. The various configurations it consists of are proxy, remote, local, and central repository configurations.
Ans. There is an excellent use of transitive dependency in Maven. By adding transitive dependencies automatically, Maven eliminates the need to find and define the libraries that your dependencies require.
Ans. The dependency scope in Maven consists of dependencies as per the existing build stage. Also, it restricts all the dependency's transitivity. There are various types of dependency scopes available in Maven:- Compile, Test, Runtime, System, Import, etc.
Ans. The following are the different types of build profiles:-
Global - This build profile is defined within the global settings.xml file of Maven.
Ans. To automatically run the clean plugin, you have to place it within the pom.xml files' execution tag.
Ans. In Maven, the POM must configure the groupID, version, and artifactID, which form the completely qualified artefact name. You can write this as
Ans. We can easily use the "mvn site" command to create a Maven site.
Ans. Pre-Clean, Clean, and Post-Clean are the various stages of the clean lifecycle in Maven.
Ans. In Maven, a local repository is a storage folder or a directory within the system where the Maven runs. Using a local repository to store JAR files is better because it takes less storage space. Also, it checks out a project much faster without using the versioning of JAR files.
Ans. In Maven, Snapshot refers to a special version under the Maven package that specifies the latest development code. For each build, Maven searches for a new SNAPSHOT version inside a remote repository, unlike standard versions.
