Top 15 Maven Interview Q&A

MAVEN:

At first glance Maven can appear to be many things, but in a nutshell Maven is an attempt to apply patterns to a project's build infrastructure in order to promote comprehension and productivity by providing a clear path in the use of best practices. Maven is essentially a project management and comprehension tool and as such provides a way to help with managing:

Builds
Documentation
Reporting
Dependencies
SCMs
Releases
Distribution

Maven Setup with Linux

Maven can be set up on Linux in a few easy steps. Installing JDK is the first step because Maven requires it to function. We will learn how to install Maven in Ubuntu in this guide. The procedures are universal, therefore they will be successful on any other Linux machine.

Install JDK on Linux/Ubuntu

Typically, we install everything in Ubuntu using the apt package manager. However, it is missing the most recent JDK packages. Although OpenJDK versions 8 and 11 are the only ones that are currently available, Java 13 is currently in use. Therefore, we will set up the necessary environment variables and install JDK using binaries.

Step 1: Download the JDK Binaries

Go to the URL: https://jdk.java.net/13/

Copy the download link for Linux/x64 build.

Then use the below command to download and extract it.

$ wget https://download.java.net/java/GA/jdk13.0.1/cec27d702aa74d5a8630c65ae61e4305/9/ GPL/openjdk-13.0.1_linux-x64_bin.tar.gz
$ tar -xvf openjdk-13.0.1_linux-x64_bin.tar.gz
$ mv jdk-13.0.1 /opt/

I have moved JDK to /opt, you can keep it anywhere in the file system.

Step 2: Setting JAVA_HOME and Path Environment Variables

Open .profile file from the home directory and add the following lines to it.

JAVA_HOME='/opt/jdk-13.0.1'
PATH="$JAVA_HOME/bin:$PATH"
export PATH

You can relaunch the terminal or execute source .profile command to apply the configuration changes.

TIPS: If you don’t find the .profile then create a new file with the name as .profile

Step 3: Verify Java Installation

You can run a java -version command to verify the JDK installation.

$ java -version
openjdk version "13.0.1" 2019-10-15
OpenJDK Runtime Environment (build 13.0.1+9)
OpenJDK 64-Bit Server VM (build 13.0.1+9, mixed mode, sharing)
$

Installing Maven on Linux/Ubuntu

We will install Maven in a similar way that we have installed JDK in the Linux system.

Step 1: Download the Maven Binaries

Go to the URL: https://maven.apache.org/download.cgi

Copy the link for the “Binary tar.gz archive” file.

Then run the following commands to download and untar it.

$ wget https://mirrors.estointernet.in/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
$ tar -xvf apache-maven-3.6.3-bin.tar.gz
$ mv apache-maven-3.6.3 /opt/

Step 2: Setting M2_HOME and Path Variables

Add the following lines to the user profile file (.profile).

M2_HOME='/opt/apache-maven-3.6.3'
PATH="$M2_HOME/bin:$PATH"
export PATH

Relaunch the terminal or execute source .profile to apply the changes.

Step 3: Verify the Maven installation

Execute mvn -version command and it should produce the following output.

$ mvn -version

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /opt/apache-maven-3.6.3
Java version: 13.0.1, vendor: Oracle Corporation, runtime: /opt/jdk-13.0.1
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.4.225-139.416.amzn2int.x86_64", arch: "amd64", family: "unix"

That’s all. Maven is successfully installed in your Linux system.
