Maven - Creating Project

Maven uses archetype plugins to create projects. To create a simple java apppcation, we ll use maven-archetype-quickstart plugin. In example below, we ll create a maven based java apppcation project in C:MVN folder.

Let s open the command console, go to the C:MVN directory and execute the following mvn command. Make sure that C:MVN directory is empty before running the command.

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

Maven will start processing and will create the complete java apppcation project structure.

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

C:MVN>

Now go to C:/MVN directory. You ll see a java apppcation project created, named consumer Banking (as specified in artifactId). Maven uses a standard directory layout as shown below −

Using the above example, we can understand the following key concepts −

If you observe, you will find that Maven also created a sample Java Source file and Java Test file. Open C:MVNconsumerBankingsrcmainjavacomcompanynameank folder, you will see App.java.

package com.companyname.bank;

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

Open C:MVNconsumerBankingsrc estjavacomcompanynameank folder to see AppTest.java.

package com.companyname.bank;

import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;

/**
 * Unit test for simple App.
 */
pubpc class AppTest extends TestCase {
   /**
   * Create the test case
	*
   * @param testName name of the test case
   */
   pubpc AppTest( String testName ) {
      super( testName );
   }

   /**
   * @return the suite of tests being tested
   */
   pubpc static Test suite() {
      return new TestSuite( AppTest.class );
   }

   /**
   * Rigourous Test :-)
   */
   pubpc void testApp() {
      assertTrue( true );
   }
}

Developers are required to place their files as mentioned in table above and Maven handles all the build related complexities.

In the next chapter, we ll discuss how to build and test the project using maven Build and Test Project.
