Maven项目中创建可执行jar时出错

Question

I have created a maven project and writing tests in it using testng. I have also created an executable jar using mvn package command but getting error when executing it. I could not actually figure out the error. Please help me with this.

$java -jar apitesting1-0.0.1-SNAPSHOT.jar 
Exception in thread "main" java.lang.NoClassDefFoundError: org/testng/ITestListener
Caused by: java.lang.ClassNotFoundException: org.testng.ITestListener

Could not find the main class: apitesting1.apitesting1.App. Program will exit.

This is my main class

public class myClass 
{
    public static void main( String[] args )
    {

    }
}

This is my pom.xml

<modelVersion>4.0.0</modelVersion>
<groupId>abc</groupId>
<artifactId>abc</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

                              </execution>
                 </executions>

                    <archive>
                        <manifest>
                           <addClasspath>true</addClasspath>
                                <mainClass>abc.abc.myClass</mainClass>
                        </manifest>
                    </archive>
                </configuration>
          </plugin>

I am new to Maven.. and copied some of the contents of pom.xml (specifically) from various places.. Please let me know if there is any redundant data or tag. I however feel that there is.. Please help.

Thanks :)

The main class element must contain the name of a class. The name of your class is apitesting1.apitesting1.App , not src/main/java/apitesting1.apitesting1.App.java .
