Maven Build Java Project

Maven uses archetype archetype plugin to create a project. To create a simple Java application, we will use maven-archetype-quickstart plugin.

In the following example, we will create a Java application project based on maven under the C:\MVN folder.

Command format is as follows:

mvn archetype:generate"-DgroupId=com.companyname.bank"-DartifactId=consumerBanking"-DarchetypeArtifactId=maven"-archetype-quickstart"-DinteractiveMode=false"

Parameter description:

• -DgroupId: Organization name, the reverse of the company's website + Project name

• -DartifactId: Project name-: Module name

• -DarchetypeArtifactId: Specify ArchetypeId, maven-archetype-quickstart, create a simple Java application

• -DinteractiveMode: Is interactive mode used

The generated folder structure is as follows:

Description of each folder:

In C:\MVN\consumerBanking\src\main\java\com\companyname\bank In the folder, you can see an App.java file, the code is as follows:

package com.companyname.bank;
　
/**
　*　Hello world!
　*
　*/
public class App　
{
　　　　public static void main(String[] args)
　　　　{
　　　　　　　　System.out.println("Hello World!");
　　　　}
}

Open C:\MVN\consumerBanking\src\test\java\com\companyname\bank folder, you can see the Java test file AppTest.java.

package com.companyname.bank;
　
import.junit.framework.Test;
import.junit.framework.TestCase;
import junit.framework.TestSuite;
　
/**
　*　Unit test for simple App.
　*/
public class AppTest extends TestCase　
{
　　　　/**
　　　　　*　Create the test case
　　　　　*
　　　　　*　@param testName name of the test case
　　　　　*/
　　　　public AppTest( String testName )
　　　　{
　　　　　　　　super( testName );
　　　　}
　
　　　　/**
　　　　　*　@return the suite of tests being tested
　　　　　*/
　　　　public static Test suite()
　　　　{
　　　　　　　　return new TestSuite( AppTest.class );
　　　　}
　
　　　　/**
　　　　　*　Rigourous Test :-)
　　　　　*/
　　　　public void testApp()
　　　　{
　　　　　　　　assertTrue( true );
　　　　}
}

During the subsequent development process, we only need to place the structure mentioned in the above table properly, and Maven will take care of the rest.
