从maven安装配置到idea成功创建maven项目

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

  | This is the configuration file for Maven. It can be specified at two levels:
  |
  |  1. User Level. This settings.xml file provides configuration for a single user,
  |                 and is normally provided in ${user.home}/.m2/settings.xml.
  |
  |                 NOTE: This location can be overridden with the CLI option:
  |
  |                 -s /path/to/user/settings.xml
  |
  |  2. Global Level. This settings.xml file provides configuration for all Maven
  |                 users on a machine (assuming they're all using the same Maven
  |                 installation). It's normally provided in
  |                 ${maven.home}/conf/settings.xml.
  |
  |                 NOTE: This location can be overridden with the CLI option:
  |
  |                 -gs /path/to/global/settings.xml
  |
  | The sections in this sample file are intended to give you a running start at
  | getting the most out of your Maven installation. Where appropriate, the default
  | values (values used when the setting is not specified) are provided.

　　上面的setting文件,使用的是国内的阿里云镜像环境,使用时只需将本地仓库的路径改下即可,整个文件直接放入maven文件夹下conf文件夹中,

　　为保险起见,博主建议在本地仓库文件夹中也放一份

　　ok,操作完这些,总得检测下是否配置正确

四. 检测本地maven的配置情况是否成功

　　1.windows+R 进cmd  敲入 mvn help:system

　　2.若出现下图,说明配置成功

　　

　　至此,maven的安装配置结束

五.在idea中创建maven项目

　　先说明下,如果你之前在idea创建maven项目失败,楼主建议将idea的配置全部删除,重新格式化idea配置,不然以下方法依然解决不了问题(亲测)

　　1.打开idea  File > New > Project     选中Maven

　　2.在 Create from archetype 前面打对勾

　　3.选择 如图所示 然后 next

　　

　　

　　4.随便填

　　　

　　5.这里一定要填写正确,填写maven的安装路径和配置文件 以及自己的仓库路径

　　

6. 填写项目名,设置项目路径  然后finish

　　

7. 如下图,若出现maven在控制台加载 可以选择让maven自动加载 Enable Auto Import

　　      

　　第一次加载可能会有点慢,因为本地没有jar包,需要去下载

　　ok 至此maven项目搭建完成    点开项目的pom文件,即可添加项目所需jar包的连接,maven即可正常使用

　　下图为项目文件列表

　　

　　好了,开始 coding 吧 ,楼主记住了这次教训,花费大把时间,属实蛋疼
