The first part covers the basic maven interview questions.
Q1. What is Maven, and why is it used?
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.
Q2. What are the Aspects Maven Managed?
Maven provides developers with ways in which to manage the following:
- Mailing list
Q3. What Is Pom? What Information Does Pom Contain?
POM stands for Project Object Model. It’s a basic Unit of work in Maven. It’s an XML file. It perpetually resides within the base directory of the project as pom.xml. To create the project(s) contains numerous configuration details and data concerning the project employed by Maven.
POM contains some of the following configuration information:
- Project dependencies
- Build profiles
- Project version
- Mailing list
Q4. What is Maven Build Lifecycle? Name the 3 Build Lifecycle of Maven.
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.
The three build lifecycles are:
- Clean: Cleans up artifacts created by previous builds.
- Default (or build): This can be accustomed to build the appliance.
- Site: Generates site documentation for the project.
Q5. What is Maven Artifact?
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)
The first part covers the advanced maven interview questions.
Q6. What are the Phases of a Maven Build Lifecycle?
Some major principles of agile testing are:
The following are the phases:
- Validate: The project is correct, and all necessary information is offered.
- Compile: The source code of the project.
- Test: The compiled source code employs an appropriate unit testing framework, and these tests should not require the code to be deployed or packaged.
- 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.
- Verify: Run any tests to verify the package is still valid and meets quality requirements.
- Install: Alternative projects will use the package from the native repository as a regional dependency.
- Deploy: Copies the final package to the remote repository for sharing with alternative projects and developers. It is done in an integration or release environment,
Q7. What is a Maven Repository?
A Maven repository is a location where all the plugins, libraries, jars, project jars, or any other particular project-related information is stored and can be easily used by Maven.
There are 3 types of maven repositories:
- Local repository
- Central repository
- Remote repository
Q8. What is a Maven snapshot?
A snapshot version of Maven is not a real version, and that will not have been released. An equivalent version might get several updates. Usually, exposure dependencies ought to exist solely throughout development, and no free version (non-snapshot) ought to depend on a snapshot version.
Q9. What features should a build tool have?
A build tool should have the following:
Compile Java code and build jar, war, and ear files for deployment and release.
- Versioning and dependency management.
- Run take a look at and report test results.
- Run code quality check with Sonar, check style, Find bugs, etc.
- Environment property substitution.
- Files generations (WSDL, AspectJ, XSL, etc.)
- Support for cross-platform (UNIX Windows) and IDEs (Eclipse, Netbeans, IntelliJ)
- Proper documentation and support.
Q10. List out the dependency scope in Maven.
The various dependency scope employed in Maven are:
- Compile: The default scope offers the dependency within the project’s classpath.
- Provided: It indicates that the dependency is provided by JDK or an internet server or container at runtime.
- Runtime: This tells that the dependency isn’t required for compilation but is needed throughout the execution.
- Test: It says dependency is offered just for the take-a-look-at compilation and execution phases.
- System: It indicates you have got to give the system path.
- Import: This means that the known or nominative pom ought to get replaced with the dependencies in this POM section.
