No main manifest attribute in jar Maven and Spring Boot

And when I run JAR using command

I am getting following error.

How to fix it?

Look for spring-boot-maven-plugin in build section in your pom.xml. If not available, include it.

    <build>
      <plugins>
         <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
    </build>

in your pom.xml
