eclipse下配置maven的下载镜像

1.逐项打开：eclipse->preference->Maven->user Settings 。按窗口中的User Settings文本框显示的路径，创建settings.xml文件，也可以修改路径过后创建该文将。

2.关闭窗口重新打开过后会出现"open file",点击"open file"，在eclipse中打开该配置文件，出现"could not read settings.xml"不需要管。直接在eclipse中添加内容。

3.复制下列内容到settings.xml中。<mirror></mirror>部分为下载镜像设置。该内容为国内阿里的镜像

<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

            repository. The repository that | this mirror serves has an ID that matches   
            the mirrorOf element of this mirror. IDs are used | for inheritance and direct   
            lookup purposes, and must be unique across the set of mirrors. | -->
