Maven和Spring Boot-无法解析的父pom-repo.spring.io(未知主机) [英] Maven and Spring Boot - non resolvable parent pom - repo.spring.io (Unknown host)

问题描述

我正在尝试构建我的项目，但是我得到了:

I am trying to build my project but I get this:

不可解析的父POM:无法从/到spring-snapshots传输工件org.springframework.boot:spring-boot-starter-parent:pom:1.3.0.M3(

Non-resolvable parent POM: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.3.0.M3 from/to spring-snapshots (http://repo.spring.io/snapshot): repo.spring.io and 'parent.relativePath' points at no local POM @ line 16, column 10: Unknown host repo.spring.io -> [Help 2]

这是我指定pom.xml的父级的方法:

Here is how I specify the parent of my pom.xml:

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.0.M3</version>
        <relativePath></relativePath>
    </parent>

为空，因此它迫使Maven在远程存储库中寻找父级.但是，它说 repo.spring.io是未知主机.

The is empty so that it forces maven to look for the parent in the remote repository. However, it says that repo.spring.io is an unknown host.

这是我在pom.xml中定义存储库的方式:

Here is how I define the repositories in my pom.xml:

<repositories>
        <repository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/snapshot</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
        <repository>
            <id>spring-milestones</id>
            <url>http://repo.spring.io/milestone</url>
        </repository>
    </repositories>

<pluginRepositories>
    <pluginRepository>
        <id>spring-snapshots</id>
        <url>http://repo.spring.io/snapshot</url>
    </pluginRepository>
    <pluginRepository>
        <id>spring-milestones</id>
        <url>http://repo.spring.io/milestone</url>
    </pluginRepository>
</pluginRepositories>

有什么想法吗?

推荐答案

很明显，这是您的互联网连接出现问题.检查是否可以通过浏览器访问 http://repo.spring.io .如果是，请检查是否需要配置代理服务器.如果否，则应与您的互联网提供商联系.

Obviously it's a problem with your internet connection. Check, if you can reach http://repo.spring.io with your browser. If yes, check if you need to configure a proxy server. If no, you should contact your internet provider.

以下是文档，介绍如何为Maven配置代理服务器: https: //maven.apache.org/guides/mini/guide-proxies.html
