篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了从maven安装配置到idea成功创建maven项目相关的知识，希望对你有一定的参考价值。

在文章开始之前,我还是想安抚下你躁动的心情,说实话这一套操作下来的确花了我不少时间,的确头疼.

不过对于现在在看文章的你,我还是想提倡多多尝试,耐心哈,别砸键盘......废话少说切入正题

一. maven安装

　　1.确保本地装有JDK

　　2.去官网：http://maven.apache.org/download.cgi 下载自己所需的版本(在这说明,windows的安装包zip结尾)

　　3.解压本地,配置环境变量(其他博客有很多提及,在这我就不多截屏和引用了,篇幅过多)

二. 检测maven是否安装成功

　　1.WINDOWS+R 进cmd 在dos窗口敲入 mvn -v

　　2.若出现下图,说明maven安装成功并且环境变量配置成功

三. maven配置文件setting的配置

　　md....在这困了两天都没配好,百度了好久,什么改本地仓库,改镜像环境,改什么什么.....巴拉巴拉.....

　　楼主把百度的maven教程和博客的都翻遍了,还是出错,说到底咱们百度那么多不就为了能正常使用maven吗?直接提供个settings文件如下,简单粗暴

 23  | This is the configuration file for Maven. It can be specified at two levels:
 24  |
 25  |  1. User Level. This settings.xml file provides configuration for a single user, 
 26  |                 and is normally provided in ${user.home}/.m2/settings.xml.
 27  |
 28  |                 NOTE: This location can be overridden with the CLI option:
 29  |
 30  |                 -s /path/to/user/settings.xml
 31  |
 32  |  2. Global Level. This settings.xml file provides configuration for all Maven
 33  |                 users on a machine (assuming they\'re all using the same Maven
 34  |                 installation). It\'s normally provided in 
 35  |                 ${maven.home}/conf/settings.xml.
 36  |
 37  |                 NOTE: This location can be overridden with the CLI option:
 38  |
 39  |                 -gs /path/to/global/settings.xml

 43  | values (values used when the setting is not specified) are provided.
