一、下載JetbrainsCrack-3.1-release-enc.jar破解補丁
下載地址：http://idea.lanyus.com/jar/JetbrainsCrack-3.1-release-enc.jar
並將該補丁保存在bin目錄下
二、配置idea64.exe.vmoptions 與 idea.exe.vmoptions 兩個文件
找到這兩個文件並編輯：
注意D:\IntelliJ IDEA 2018.2.4\bin\JetbrainsCrack-3.1-release-enc.jar是絕對路徑，不要寫錯
三、啓動IDEA，輸入註冊代碼
在進入出現有activation code選擇界面的時候，寫入下面註冊代碼，到2100年到期：
