How to create the java stand alone project with command prompt using maven

To create a simple java project using maven, you need to open the command prompt and run the archetype: generate command of the mvn tool.

The syntax is given below:

mvn archetype:generate -DgroupId=groupid -DartifactId=artifactid -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=booleanValue

Here group id means =package name
Here artifact id menas=project name
DarchetypeArtifactId means =It is an archetype which generates a sample Maven project
DarchetypeVersion means=version of your project
Interactive mode means = If the flag value is false(the project is created in batch mode, batch-mode will automatically use default values instead of asking you via prompt for those values). when -DinteractiveMode=true, then project is created in interactive mode.

Steps to create the sample stand-alone project with maven.

Step1: After successful installation maven opens the command prompt.
Step2: Type the below command

mvn archetype:generate -DgroupId=com.quickdevops -DartifactId=sample -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false

It will generate the project directory structure with 3 files  those are:

• Pom.xml
• App.java
• AppTest.java

Here is my pom.xml file

<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/maven-v4_0_0.xsd">  
  
  <modelVersion>4.0.0</modelVersion>  
  <groupId>com.quickdevops</groupId>  
  <artifactId>sample</artifactId>  
  <packaging>jar</packaging>  
  <version>1.0-SNAPSHOT</version>  
  <name>CubeGenerator</name>  
  <url>http://maven.apache.org</url>  
  <dependencies>  
    <dependency>  
      <groupId>junit</groupId>  
      <artifactId>junit</artifactId>  
      <version>3.8.1</version>  
      <scope>test</scope>  
    </dependency>  
  </dependencies>  
</project>

Here is my App.java 

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

Here is my AppTest.java

package com.quickdevops;  
      
    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 );  
        }  
    }  

To run the application following the commands

• For Cleaning the project: mvn clean
• For compiling the project: mvn compile
• For packaging the project: mvn package, mvn install (it will generate the jar file).
• To run the project (Go to target and folder open the command prompt type the following command: java -jar filename.)
