Maven adding mainClass in pom.xml with the right folder path

First, your main class doesn't include src/main/java. Look at the package declaration in that Java file. For example, package org.jis;, then add the main class to that. In other words, it's only org.jis.Main.

You need to configure the maven-jar-plugin instead the of the maven-compiler-plugin. The jar-plugin is the one which is responsible for packaging and creating the manifest.MF.

From http://maven.apache.org/shared/maven-archiver/examples/classpath.html

  <build>    <plugins>      <plugin>        <groupId>org.apache.maven.plugins</groupId>        <artifactId>maven-jar-plugin</artifactId>        ...        <configuration>          <archive>            <manifest>              <addClasspath>true</addClasspath>              <mainClass>fully.qualified.MainClass</mainClass>            </manifest>          </archive>        </configuration>        ...      </plugin>    </plugins>  </build>

You may mention as below if it's a spring boot application.

<build>    <plugins>        <plugin>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-maven-plugin</artifactId>            <configuration>                <mainClass>com.test.MainClass</mainClass>            </configuration>                           </plugin>    </plugins></build>

Basically Maven is a framework which have a collection of maven-plugin for each and every action performed to build a project.

Each Build Phase is performed by corresponding maven-plugin using project's description Project Object Model(POM)

So maven-compiler plugin is just responsible to compile the project and it won't create the manifest file.

maven-jar-plugin is responsible for creating the manifest file of the project.
