一、下载
下载地址：https://www.jetbrains.com/idea/download/other.html
建议下载旗舰版（Ultimate），功能比较齐全，而社区版（Community）虽然是免费，但功能相对不是很丰富。此处我选择的是2018.2.8版本。
二、安装
2.1、双击下载好的.exe程序
2.2、点击next
2.3、可自定义安装路径
2.4、勾选相应框后点击next
2.5、点击install
2.6、静待安装后，点击finish即可，暂且不用打开IDEA。
三、破解
3.1、先下载破解所需要的jar包：JetbrainsCrack-3.1-release-enc.jar
链接: https://pan.baidu.com/s/1iwjuV_Mxq_CraSC3W6tnyA 提取码: e7w4
3.2、将下载好后的jar包放入IDEA安装的bin目录下
3.3、修改bin目录下的 idea.exe.vmoptions 和 idea64.exe.vmoptions配置文件。分别在这两个配置文件，最下面添加下面这一行代码：
-javaagent:D:\Dpan\Program Files\idea\JetBrains\IntelliJ IDEA 2018.2.8\bin\JetbrainsCrack-3.1-release-enc.jar（-javaagent:后的地址即为刚才下载的jar包存放的地址。）
3.4、运行IDEA。
3.5、数据共享
3.6、是否使用文件进行配置，新安装就无须配置，直接点击OK。
3.7、接受条款
3.8、界面风格选择
3.8、选择Activition Code，输入激活码，破解成功。
