Road to create executable jar using maven

In this post I explained the procedure to create executable jar file using maven build tool.

You need to create java maven project using eclipse.

Here is example of a java class having main method.

package com.test;

 import org.junit.Assert;

 public class VerifyString {

   public boolean matchString(String str1, String str2){

      if(str1.equals(str2)){

          System.out.println("both strings are equal");

          return true;

      }

      else {

          System.out.println("both strings are not equal");

          return false;

        }

    }

    public static void main(String[] str){

      VerifyString verifyString = new VerifyString();

      Assert.assertTrue(verifyString.matchString("Akib", "Akib"));

      Assert.assertFalse(verifyString.matchString("Akib", "Sachin"));  

   }

}

pom.xml

               </configuration>

            </execution>

         </executions>

       </plugin>

    </plugins>

  </build> 

</project>

Run below commands to create jar

  

  mvn clean

  mvn install

After build success, you should see a “maven-junit-test.jar” executable jar file created under “traget” folder in maven java project.
