Maven – Configuring Dependencies

Maven – Configuring Dependencies:
When we create a maven project, By default pom.xml will be generated.

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>MavenTest</groupId>
    <artifactId>Profile</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>  
</project>

Model Version:
Model Version is the version of POM model

Artifact Id:
Contains the name of the project which we create

Group Id:
GroupId is an unique id for the project.

Version:
Version is the version number of the project. A project might have multiple releases, So the version number indicates the version release of the project

Packaging:
Type of project packaging.

Now let us include a dependency inside the project, We can get the dependencies here – Maven Repository

Let us include Spring context dependency and check for the dependency download.
Let us include this dependency inside POM.xml

<!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.3.3.RELEASE</version>
</dependency>

Before we include this dependency, The dependency should be enclosed between <dependencies> tag.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>MavenTest</groupId>
    <artifactId>Profile</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>
    <dependencies>
        <!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
    <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-context</artifactId>
       <version>4.3.3.RELEASE</version>
    </dependency>
    </dependencies>
    
</project>

When we right click the project and select “build with dependencies”, the jars are downloaded with the help of these dependencies.
