空手去破解
将下载的文件放到安装IDEA路径的bin目录下（如图）
找到idea.exe.vmoptions和idea64.exe.vmoptions，用notepad++（或记事本）打开它们。
最后一行加上下面的：
-javaagent:C:IntelliJ IDEA 2017.3.5inJetbrainsCrack-2.7-release-str.jar
注意：要修改JetbrainsCrack的路径。
修改Activation Code
重启Intellij IDEA，在Activation Code输入：
ThisCrackLicenseId-{重启Intellij IDEA，在Activation Code输入：

"licenseId":"ThisCrackLicenseId",
"licenseeName":"你想要的用户名",
"assigneeName":"",
