项目构建错误：不可解析的父 POM：无法解析以下工件

Question

当我尝试创建 Spring Boot 文件时收到一条错误消息，它给了我一个特定的错误代码。

Project build error: Non-resolvable parent POM for com.example:demo:0.0.1-SNAPSHOT: The following artifacts could not be resolved: org.springframework.boot:spring-boot-starter-parent:pom:3.2.3 (absent): org.springframework.boot:spring-boot-starter-parent:pom:3.2.3 failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not 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:3.2.3 from/to central (https://repo.maven.apache.org/maven2): No such host is known (repo.maven.apache.org) and 'parent.relativePath' points at no local POM

当我查看 pom.xml 文件时，它在这一行显示错误。

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.2.3</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

我尝试通过不同的互联网连接进行连接，甚至尝试更改不同版本的 Java 和 Spring boot。

从命令行运行

mvn install

时是否出现错误？还是通过IDE？

我在使用 IDE 时遇到过类似的情况，这是该 IDE 中的一个错误。
