IntelliJ IDEA中快速解决 Maven Connection timed out 问题

在国内连接 Maven 官方的中央库会出现Connection timed out问题。 出错提示

[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]

解决办法有：

1.在.m2/settings.xml中添加国内的镜像站，例如

    
        nexus-aliyun
        *
        Nexus aliyun
        http://maven.aliyun.com/nexus/content/groups/public
    

下载settings.xml文件

2.IntelliJ IDEA中配置自定义的settings.xml文件
