An example of building Java project using Maven

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:

import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class MavenSandboxTest {
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="" xmlns:xsi="" 

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“:


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:
