spring boot pom.xml传输失败

Question

我刚刚创建了一个新的Spring Boot项目，但我在pom.xml中遇到了一个问题，我不知道如何解决它，请提供一些帮助，谢谢大家。

父标记whitch中的pom.xml it中的错误是：

项目生成错误：COM的父POM不可解析。示例：ProjetTest:0.0.1-快照：无法传输org.springframework.boot:spring-boot-starter-parent:POM:2.0.0。来自https://repo.maven.apache.org/maven2的版本已缓存在本地存储库中，在central的更新间隔已过或强制更新之前，将不会重新尝试解析。原始错误：无法传输项目org.springframework.boot:spring-boot-starter-parent:POM:2.0.0。从/到中央版本(https://repo.maven.apache.org/maven2):连接被拒绝：连接且“parent.relativePath”不指向本地POM

要尝试的东西

1. 您可以尝试替换开始的 标记，如下所示:-

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
            http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <!-- Other stuff of the pom.xml here -->
</project>
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <!-- use your specific version here -->
    <version>2.0.0.RELEASE</version>
</parent>
如果它仍然没有解决，那么它可能是各种各样的事情，例如：-
    

     null
