目前在用的是2020.1，想升級一下最新的2021.2。官網上下載的最新的，安裝。安裝完成后，首次啟動，發現自動的在下載2020.1在用的插件。恩，很智能嘛。插件下載完后，沒動靜了。雙擊圖面圖標，依然沒有動靜，+++，真不能誇。這下子完了，啟不來了。。。
問題描述：2021.2啟動不了，雙擊桌面圖標，沒有響應；CMD里輸入idea有報錯。
進入到安裝目錄C:\JetBrains\IntelliJ IDEA 2021.2\bin（我自己選的，默認不在這里），打開CMD。輸入idea，發現有報錯。

錯誤信息一大堆，關鍵的一句
FATAL ERROR in native method: processing of -javaagent failed, processJavaStart failed
問題1：這個參數不是我添加進去的，哪來的???
打開idea.bat，在代碼最后處，加上輸出
#這里是我加入的 echo %CLASS_PATH% echo %ACC% echo %IDE_PROPERTIES_PROPERTY% #下面的這些是原始的 "%JAVA_EXE%" ^ -cp "%CLASS_PATH%" ^ %ACC% ^ "-XX:ErrorFile=%USERPROFILE%\java_error_in_idea_%%p.log" ^ "-XX:HeapDumpPath=%USERPROFILE%\java_error_in_idea.hprof" ^ -Djava.system.class.loader=com.intellij.util.lang.PathClassLoader -Didea.vendor.name=JetBrains -Didea.paths.selector=IntelliJIdea2021.2 -Didea.jre.check=true ^ %IDE_PROPERTIES_PROPERTY% ^ com.intellij.idea.Main ^ %*
重新執行idea.bat（在CMD里哦），發現如下輸出
-Djb.vmOptionsFile="C:\Users\cpp\AppData\Roaming\JetBrains\IntelliJIdea2021.2\idea64.exe.vmoptions" "-Xms128m" "-Xmx1012m" "-XX:ReservedCodeCacheSize=240m" "-XX:+UseConcMarkSweepGC" "-XX:SoftRefLRUPolicyMSPerMB=50" "-ea" "-XX:CICompilerCount=2" "-Dsun.io.useCanonPrefixCache=false" "-Djdk.http.auth.tunneling.disabledSchemes=""" "-XX:+HeapDumpOnOutOfMemoryError" "-XX:-OmitStackTraceInFastThrow" "-Djdk.attach.allowAttachSelf=true" "-Dkotlinx.coroutines.debug=off" "-Djdk.module.illegalAccess.silent=true" "-javaagent:C:\Users\Public\.jetbrains\jetbrains-agent-v3.2.0.de72.619"
OpenJDK 64-B
看到 -javaagent 這個參數了嗎。近一步發現這個 -javaagent 是在%ACC%變量里。
下一步，查找 %ACC%，發現在idea.bat里，並沒有直接對其設置值，猜想一定是調用了另外的bat文件，對其設置值的，按照這個思路，append.bat，進入了視線。在約在idea.bat里，114行，加上輸出
echo aaaaaaa\%VM_OPTIONS_FILE% FOR /F "eol=# usebackq delims=" %%i IN ("%VM_OPTIONS_FILE%") DO CALL "%IDE_BIN_DIR%\append.bat" "%%i" IF NOT "%USER_VM_OPTIONS_FILE%" == "" ( FOR /F "eol=# usebackq delims=" %%i IN ("%USER_VM_OPTIONS_FILE%") DO CALL "%IDE_BIN_DIR%\append.bat" "%%i" ) )
發現有使用到
C:\Users\cpp\AppData\Roaming\JetBrains\IntelliJIdea2021.2\idea64.exe.vmoptions 這個文件，記事本直接輸入該文件，還真有這個文件。內容如下所示：
-Xms128m -Xmx1012m -XX:ReservedCodeCacheSize=240m -XX:+UseConcMarkSweepGC -XX:SoftRefLRUPolicyMSPerMB=50 -ea -XX:CICompilerCount=2 -Dsun.io.useCanonPrefixCache=false -Djdk.http.auth.tunneling.disabledSchemes="" -XX:+HeapDumpOnOutOfMemoryError -XX:-OmitStackTraceInFastThrow -Djdk.attach.allowAttachSelf=true -Dkotlinx.coroutines.debug=off -Djdk.module.illegalAccess.silent=true -javaagent:C:\Users\Public\.jetbrains\jetbrains-agent-v3.2.0.de72.619
好了，看到 -javaagent:C:\Users\Public\.jetbrains\jetbrains-agent-v3.2.0.de72.619 這一行，是不是定義到問題了，趕緊刪除這一行，再次輸入 idea，久違的啟動畫面出現了。
最后，終結一下，不是ieda做的不好。而是目前在用的2020.1，破解了（為什么破解你的懂的）。然后安裝新版后，由於IEDA太智能了，智能的太過頭了，把現有的啟運參數也都復制過去了。又因為最新的IEDA，不兼容破解程序 C:\Users\Public\.jetbrains\jetbrains-agent-v3.2.0.de72.619了，所以報錯了，所以JVM結束了，所有沒有啟動畫面了，所以就涼涼了。
另外，有嘗試過，報錯不是提向了 :C:\Users\Public\.jetbrains\jetbrains-agent-v3.2.0.de72.619這個文件嗎，那么我刪除這個文件會怎樣呢？事實證明，如下所示：
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release. Error opening zip file or JAR manifest missing : C:\Users\Public\.jetbrains\jetbrains-agent-v3.2.0.de72.619 Error occurred during initialization of VM agent library failed to init: instrument
DEBUG流程：idea.bat -> append.bat --> C:\Users\cpp\AppData\Roaming\JetBrains\IntelliJIdea2021.2\idea64.exe.vmoptions
最后，寫上遇到的錯誤
