1.先下載Crack這裡寫連結內容
2.複製 JetbrainsCrack.jar到idea安裝目錄的 “bin”資料夾
3.修改bin目錄的” idea.exe.vmoptions” 或者 “idea64.exe.vmoptions”) 檔案:
在最後新增一行內容：-javaagent: {InstallDir} /bin/JetbrainsCrack.jar
比如： -javaagent: D:\java\IntelliJ IDEA 2018.1\bin\JetbrainsCrack.jar
Note: “-javaagent: D:\java\IntelliJ IDEA 2018.1\bin…” – 注意不要有空格!
4.開啟idea.（選第二項，貼上金鑰）
5.複製下面的key值，貼上即可
