    </build>

</project>

-->获取此行中的错误为

Project build error: Non-resolvable parent POM for com.example:demo:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.4.5 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.4.5 from/to central (https://repo.maven.apache.org/maven2): connect timed out and 'parent.relativePath' points at no local POM
