Cannot resolve org.springframework.boot:spring-boot-autoconfigure:2.6.1 springboot | dubbo

When I used maven to import the jar package of dubbo-spring-boot-start, the following error occurred:

[INFO] Validation error:

Springboot 2.6.1 and the dubbo-spring-boot-starter version is 2.7.3

Here is my pom.xml:

        </plugins>
    </build>

</project>

What's the reason? When I add the dubbo-spring-boot-starter jar package, I get an error, but it can run when I downgrade to 2.7.0

Delete the .m2 folder then try again, I just experienced this.
