java - spring boot pom.xml 传输失败

Question

我刚刚创建了一个新的 spring boot projet，我在 pom.xml 中遇到了问题，我不知道如何解决它，请帮忙，谢谢大家。

父标签中的 pom.xml 错误是:

项目构建错误:com.example:ProjetTest:0.0.1-SNAPSHOT 的不可解析的父 POM:传输失败 org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.RELEASE 来自https://repo.maven.apache.org/maven2缓存在本地 存储库，在中央的更新间隔结束或强制更新之前，不会重新尝试解析。原始错误:无法 转移 Artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.RELEASE 从/到中心(https://repo.maven.apache.org/ maven2): Connection refused: connect and 'parent.relativePath' points at no local POM

连接被拒绝

Answer 1

尝试的事情

1. 您可以尝试替换您的开头 <project>标签如下:-

<p></p>

<pre><code><?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>
</code></pre>

<p></p>

1. 您需要删除 <relativePath/> parent 将如下所示:-

<p></p>

<pre><code><parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <!-- use your specific version here -->
    <version>2.0.0.RELEASE</version>
</parent>
</code></pre>

<p></p>

1. 如果仍未解决，则可能是各种原因:-

   1. 互联网连接，也可能是代理问题
   2. 尝试删除文件夹 M2_FOLDER_LOCATION\.m2\repository\org\springframework\boot\spring-boot-parent然后重新导入项目。
