Spring Boot is not compatible with this Spring Cloud release train - spring-boot

Question

I am trying to create shaded jar for my spring project with bellow pom.xml, which runs fine in IDE but when I run mvn clean package and execute the jar with java -jar .\flink-0.0.1-SNAPSHOT-test.jar I am getting:
Your project setup is incompatible with our requirements due to
following reasons:
Spring Boot [0.0.1-SNAPSHOT] is not compatible with this Spring Cloud release train
Change Spring Boot version to one of the following versions [2.6.x, 2.7.x] .
I checked spring cloud compability matrix where spring cloud 2021.0.x is compatible with spring boot 2.6.x.

Project currently contain only single Main Class:
#SpringBootApplication
public class Application
{
public static void main(String[] args)
{
SpringApplication.run(Application.class, args);
}
}

Shading the jar means that the version compatibility that checks the manifest is broken. Set spring.cloud.compatibility-verifier.enabled=false
