第一步：下载jar包，下载链接: https://pan.baidu.com/s/1u4L6InRyeRPD5iALxmSqxw 提取码: saik
第二步：将下载的jar包放到对应的idea安装目录的bin目录下，我的目录如图所示
第三步：在bin目录下的一下两个文件，如下图所示：
分别加入-javaagent:D:\Program Files\IntelliJ IDEA 2018.2.5\bin\JetbrainsIdesCrack-4.2-release-sha.jar 这段代码，
-javaagent后面跟的是刚才下载的jar包存放的路径，也就是idea安装路径下bin的路径。
第四步：重新启动idea软件，复制以下内容到Acrivation code中的空白处。
