1.下載旗艦版，建議下載2018.02版本，該版本好破解。
2.安裝 直接點擊安裝，一直下一步即可。注意安裝的盤符，最好放在C盤。
其中有一步說明一下（具體直接看圖中文字描述）
破解步驟
首先，你需要去下載一個破解補丁，JetbrainsIdesCrack-3.4-release.jar 提取碼：q0il
將下載好的jar包放在IDEA的安裝目錄的bin路徑下，找到“idea64.exe.vmoptions”,因為我是64位所以修改這個文件，如果你是32位，可以修改“idea.exe.vmoptions”
在文件最后加上：-javaagent:D:\IntelliJ IDEA 2018.2.8\bin\JetbrainsCrack-3.1-release-enc.jar 地址即為剛才下載的jar包存放的地址。
點擊運行，是否使用文件進行配置，新安裝就無須配置，直接點擊OK
選擇Activition Code，輸入激活碼，破解成功。
接下來，把下面的一段代碼進行修改后復制。
