4.
What is a Maven?01.
Apache Maven is a software project management and comprehension tool. Based on the
concept of a project object model (POM), Maven can manage a project's build, reporting
and documentation from a central piece of information.

5.
What are the main features of Maven?02.
• Simple and Fast
• Easy to learn
• Dependency management
• Multiple projects
• Large library
• Extensible
• Instant
www.edureka.co

6.
What are the functions of a build tool?03.
• Generate
• Documentation

• Package
• Install
www.edureka.co

7.
Why should one use Maven?04.

8.
List the differences between ANT and Maven.05.
www.edureka.co

9.
Mention the steps for installing Maven.06.

10.
What does it mean when you say Maven uses
Convention over Configuration?
07.

15.
What is Maven artifact?11.
An artifact is a file, usually a JAR that gets deployed to a Maven repository. A Maven build

www.edureka.co

16.
What is Maven Build Lifecycle?12.
A Build Lifecycle is a well-defined sequence of phases. It defines the order in which the
goals are to be executed. Each build phase consists of a sequence of goals.
www.edureka.co

17.
Name the 3 build lifecycles of Maven.13.
• clean:cleans up artifacts created by prior builds.
• default (or build):This is used to build the application.

18.
What is the command to quickly build your Maven
site?
14.
Type the command − mvn site

build process.
www.edureka.co

20.
What are the phases of a Maven Build Lifecycle?16.
• Validate
• Compile
• Test
• Package
• Integration test
• Verify
• Install
• deploy
www.edureka.co

21.
What is a goal in Maven terminology?17.
A goal represents a specific task which contributes to the building and managing of a
project. It may be bound to zero or more build phases.
www.edureka.co

What would this command do mvn clean
dependency:copy-dependencies package?
18.
This command will clean the project, copy the dependencies and package the project
(executing all phases up to package).

repository?
23.
~/m2./repository
www.edureka.co

30.
What is Build Profile?24.

default values of Maven build
www.edureka.co

31.
