一、maven安装
maven：自动构建项目、自动导包、契约编程
安装：
1.解压文件
2.配置环境变量
添加path路径：
3.cmd查看是否配置成功
4.更改仓库路径（可以改可以不改）
自定义仓库路径，复制（图1）settings.xml至.m2下（图2），并添加自定义路径（图3）
同样在settings.xml中配置国内仓库（阿里云仓库），下载速度快
二、idea安装
1.傻瓜式安装
2.破解
根据版本号下载相应补丁
3.将补丁放置软件安装后的根目录下
4.修改根目录下idea64.exe.vmoptions（64位）
idea.exe.vmoptions（32位）
打开并在末尾加上
-javaagent:D:\IntelliJ_IDEA_2018.3.3\bin\JetbrainsIdesCrack-4.2-release.jar
ps：红色字体为你安装路径，蓝色字体为破解jar包名。
5.运行idea
