A maven is a tool used for software project management and comprehension. Most of the times it is used with projects or software developed in Java, and other programming languages such as Ruby and C#.

This software project management tool is used for-
  • documentation, managing builds, SCM (software configuration management)
  • reporting, releases, dependencies
  • project compilation within the IDE with the help of several IDEs.
  • Helps in better debugging
  • Enhanced collaboration
  • Clean generated files from the project such as .class files
  • Improved dependency management
  • Project structure consistency

POM, Project Object Model is the fundamental work unit in Maven. Basically, it is an XML file containing details of the configuration and project information with the help of Maven for building the project. The best thing is the availability of the default values for the projects.

  • To ease handling of the dependencies on the availability of a lot of dependencies
  • Updating the dependencies by choosing the correct update version ID
  • Facilitating the process of building, integrating and testing of the program along with handling it continuously
  • Compiling the source code, generating documents from it and packaging the compiled code.

Maven install is used for framing a project configuration-based dependency tree such as pom.xml. On an mvn install, framing project is done on all the subjects under downloads/compiles and super pom.xml for all the required components in the directory

It is the directory of the JAR files which are packaged and that too with some metadata which are POM files. These are the files used for downloading dependencies of your dependencies till the time when all of them are downloaded. These are put into the local machine.

There are three types of Maven repository, namely-
  • Local repository
  • Central repository
  • Remote repository
S.no Apache Ant Maven
1. No formal conventions arise the requirement of providing project structure information in the build.xml file Availability of the conventions by placing compiled code and source code i.e., no information sharing requirement in the project structure in pom.xml.file
2. The absence of life cycle in Apache Ant Presence of the life cycle in Maven
3. It is a toolbox mainly of the building nature It is a framework primarily project management tool

Maven build life cycle is the sequence of the steps for the execution of the goals and tasks of any Maven project. The categories under Maven build life cycle are default, clean and site. Here, the default lifecycle handles the deployment of the project and whereas, the clean life cycle considers the cleaning of the project. The task of handling the creation of the documentation of the project is dealt with by site lifecycle.

It is one of the most common Maven Interview Question and most accessible to answer and remember.

In Maven, snapshots are used for active projects. You can entirely rely on the snapshot release when you have software development projects are active. Here, Maven attempt to download the snapshots, when the user runs the build, from a repository.

S.no Maven Built Maven Install
1. It is not one of the phases of standard Maven lifecycles It is a phase in the Maven lifecycle’s standard
2. Creation of the new run configuration, while the launch of the previous dialogue is done by Maven, built Installed in Eclipse with the goal install
S.no Maven Plugin Maven Dependency
1. Preferred for most of the work Used while task implementation by adding to the classpath
2. Difficult to manage Easy management
3. Create JAR files, unit test code, compile code Reproducible builds are defined, created and maintained
