Q1. What is Maven, and why is it used?

Answer:
While building the software system, you would like to perform the subsequent tasks no matter your event methodology.

  • Gather necessities
  • Analyze necessities
  • Design solution
  • Develop (code) solution
  • Test solution
  • Deploy solution
  • Maintain solution

The above tasks are usually executed in the order listed above. For example, you cannot develop a solution before analyzing and designing the requirements. Some may argue that with Test Driven Development (Book), the test cases are created before the solution is developed. The tests are executed after development, regardless of when they were designed.

If permitted, the associate assistant may handle the repetitive steps while the team focuses on thinking. The assistant isn’t intelligent but knows the software system development flow and how to staple items. For instance, the assistant will produce the supported templates, transfer needed third-party libraries (also referred to as JARs) and their dependencies, build all elements, and build a deployable JAR, WAR, or EAR file. This assistant is termed a maven. This distinguishes Maven from alternative building tools like Hymenopteran (Homepage) or alternative build scripts.

In other words, Maven is a project management tool. Developers can utilize Maven’s complete build lifecycle framework to modify the project’s infrastructure, as Maven employs a default build lifecycle.

POM contains some of the following configuration information:

  • Project dependencies
  • Plugins
  • Goals
  • Build profiles
  • Project version
  • Developers
  • Mailing list

Q4. What is Maven Build Lifecycle? Name the 3 Build Lifecycle of Maven.

Answer:
A Build Lifecycle is a well-defined sequence of phases that outline the order in which the goals will be executed. Here phase represents a stage in the life cycle.

Q5. What is Maven Artifact?

Answer:
An artifact is a file, internally a JAR file, that gets deployed to a Maven repository. A Maven build produces one or more artifacts, such as “sources” JAR and a compiled JAR. Each artifact encompasses a group ID (usually a reversed domain name, like com.example.foo), an artifact ID (just a name), and a version string. The three unambiguously determine the artifact. A project’s dependencies are specified as artifacts.

Part 2 –Maven Interview Questions (Advanced)

  • Package: Package the compiled code in its distributable format like a JAR.
  • Integration-test: Process and deploy the package into a suitable environment for running integration tests if needed.
