Could not find artifact org.springframework:spring-webmvc:pom:${spring.version} in central

This error message indicates that the Maven build system was unable to locate the specified artifact (in this case, the Spring Web MVC framework) in the central Maven repository. The ${spring.version} placeholder in the artifact coordinate usually gets replaced with the version of the Spring framework that you are using in your project.

There could be several reasons for this error:

- The specified version of the Spring framework may not be available in the central repository. In this case, you may need to add a different repository to your Maven build configuration that contains the required version of the artifact.

- There could be a typo or syntax error in the artifact coordinate. Double-check that the group, artifact, and version are all correct.

- Your network connection may be preventing Maven from accessing the central repository. Check your internet connection and try again.

To resolve this issue, try updating the version of the Spring framework that you are using or adding a different repository to your Maven build configuration that contains the required version of the artifact. You could also try clearing your local Maven cache and re-running the build.
