The above error is generated everytime i add an application.yml/properties file to my springboot application and try to run it. Although I do not need the application.yml to run my app from intellij, I do want to run the jar file of the same and its causing an issue.

I have tried checking indentation/copy+pasted/manually typed tried everything to correct it but it just doesn't work. I am able to see my application.yml under target folder though.

None of the answers online have yet helped.

Simply including the parent tag in pom.xml worked for me. Re-build the maven project and you should be good to go.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.6.6</version>
</parent>

The first line of your exception tells you exactly what is wrong.

Exception in thread "main" java.lang.IllegalStateException: Attempted to load Config resource 'class path resource [application.yml]' via location 'optional:classpath:/' but snakeyaml was not found on the classpath

Especially the partial phrase but snakeyaml was not found on the classpath.

If we analyze your pom.xml we can see that the error stems from that. You only have spring-boot-autoconfiguration as a dependency whereas the minimal useful dependency to use is spring-boot-starter as a dpendency. This will pull in the minimal dependencies needed (logging and SnakeYaml to name 2).

            </plugin>            
        </plugins>
    </build>

</project>

With the above, cleaned up, pom.xml it should work. It will pull in the necessary dependencies like SLF4J, Snakeyaml etc. which are needed to run a Spring Boot application.

I also took the liberty to clean the plugins and the configuration thereof and remove some dependencies that are now automatically included.
