下载并安装IDEA
甩个链接，官网：https://www.jetbrains.com/idea/
下载破解补丁
新连接：JetbrainsCrack-3.1-release-enc.jar
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。
在两个文件最后分别加上（如图）
-javaagent:C:\IntelliJ IDEA 2017.3.5\bin\JetbrainsCrack-3.1-release-enc.jar
注意：上面是-javaagent:加上刚才下载的jar包的位置。
注意：要修改JetbrainsCrack的路径。
修改Activation Code
重启Intellij IDEA，在Activation Code输入：
ThisCrackLicenseId-{
"licenseId":"ThisCrackLicenseId",
"licenseeName":"你想要的用户名",
"assigneeName":"",
"assigneeEmail":"随便填一个邮箱(我填的:[email protected])",
"licenseRestriction":"For This Crack, Only Test! Please support genuine!!!",
"checkConcurrentUse":false,
"products":[
{"code":"II","paidUpTo":"2099-12-31"},
{"code":"DM","paidUpTo":"2099-12-31"},
{"code":"AC","paidUpTo":"2099-12-31"},
{"code":"RS0","paidUpTo":"2099-12-31"},
{"code":"WS","paidUpTo":"2099-12-31"},
{"code":"DPN","paidUpTo":"2099-12-31"},
{"code":"RC","paidUpTo":"2099-12-31"},
{"code":"PS","paidUpTo":"2099-12-31"},
{"code":"DC","paidUpTo":"2099-12-31"},
{"code":"RM","paidUpTo":"2099-12-31"},
{"code":"CL","paidUpTo":"2099-12-31"},
{"code":"PC","paidUpTo":"2099-12-31"}
],
"hash":"2911276/0",
"gracePeriodDays":7,
"autoProlongated":false}
然后……就成功了。到2099年，你可能要玩一辈子编程了。
