spring-boot-maven-plugin

We should provide the configuration that is responsible for packaging all dependencies into an executable JAR (sometimes called fat JARs) during application build. This action would be performed by spring-boot-maven-plugin if it is defined in the Maven pom.xml:

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