Prerequisite: download and configure Maven in your laptop. Once done, type "mvn" in command line and you should observe the following output by Maven:



Suppose I have a simple Java project with following package hierarchy:


The source code of MavenSandboxTest is also very simple:



package test.java.com.sap;
import static org.junit.Assert.assertEquals;
import main.java.com.sap.MavenSandbox;
import org.junit.Test;
public class MavenSandboxTest {
@Test
public void test() {
MavenSandbox tool = new MavenSandbox();
assertEquals(tool.hello(),"Hello world");
}
}

How to build this simple Java project using Maven?


Create a pom.xml under the root folder of your project,



and paste the following source code:



<?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/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.sap.MavenSandbox</groupId>
<artifactId>MavenSandbox</artifactId>
<version>0.0.1-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>

Create a new Configuration:



Specify the following settings and click run:



If everything goes well, you should see the Build Success message:



and there will be a new folder "target" generated automatically:



go to folder classes, and you can execute the compiled java class via command "java main.java.com.sap.MavenSandbox":



or you can also directly execute the jar file via the command below ( you should first navigate back to target folder )



since we have specified the dependency of JUnit with version 4.10 in pom.xml:



so when "mvn clean install" is executed, you can observe the corresponding jar file is automatically downloaded by Maven:



Finally you could find the downloaded jar file from this folder:
