一、问题描述

在国内连接Maven官方中央库会出现Connection timed out问题。

[ERROR] Failed to execute goal on project gs-maven: Could not resolve dependencies for project org.springframework:gs-maven:jar:0.1.0: Failed to collect dependencies at joda-time:joda-time:jar:2.2: Failed to read artifact descriptor for joda-time:joda-time:jar:2.2: Could not transfer artifact joda-time:joda-time:pom:2.2 from/to central (https://repo.maven.apache.org/maven2): Connect to repo.maven.apache.org:443 [repo.maven.apache.org/151.101.16.215] failed: Connection timed out: connect -> [Help 1]

二、解决方案

在配置文件（默认为.m2/settings.xml）中添加国内镜像站

    <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>*</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>
