本文以前是圖文教程，由於之前所采用的微博圖床失效，圖片都不顯示了，我又不想刪去這篇文章，所以便改寫成了無圖版本。
1. 下載破解文件
IDEA2017.3.4激活文件
IDEA2017.3.4軟件安裝包 提取碼：uejm
2. 將以下三個文件復制到IDEA安裝目錄下的bin目錄下
idea.exe.vmoptions
idea64.exe.vmoptions
JetbrainsCrack-3.1-release-enc.jar
分別修改idea.exe.vmoptions 和idea64.exe.vmoptions的最后一行內容，示例：
-javaagent:D:\IntelliJ IDEA 2017.3.4\bin\JetbrainsCrack-2.7-release-str.jar
-javaagent:后的地址是
JetbrainsCrack-2.7-release-str.jar文件所在的目錄。直接打開bin目錄，鼠標選擇JetbrainsCrack-2.7-release-str.jar文件，然后右鍵屬性，點擊安全，將對象名稱后面的鏈接復制進來就行了。
3. 打開IDEA輸入激活碼激活
ThisCrackLicenseId-{
"licenseId":"ThisCrackLicenseId",
"licenseeName":"你的姓名",
"assigneeName":"",
"assigneeEmail":"你的郵箱",
"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":"PC","paidUpTo":"2099-12-31"}
],
"hash":"2911276/0",
"gracePeriodDays":7,
"autoProlongated":false}
方法：打開ieda -- help -- Register --Activation code,將上面的激活碼輸進去就行
最后重啟一下idea，就破解成功了。
