According to the document, 2.2. Using the Spring Boot BOM to manage dependency versions[1], guides to use "<spring-boot-maven-plugin.version>2.4.9.RELEASE</spring-boot-maven-plugin.version>" but it must to be "2.4.9" since Spring Boot 2.4 doesn't support prefix version. It causes the following error:
```

[ERROR] No plugin found for prefix 'spring-boot' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/Users/cmoullia/.m2/repository), redhat-ga (https://maven.repository.redhat.com/ga/), central (https://repo.maven.apache.org/maven2)] -> `[Help 1]

```

So if you replace it with "2.4.9", the spring boot 2.4.9 app can be built properly.
