Intellj IDEA14.0.2啟動異常之3分鍾修復

今天是周一，剛到公司啟動心愛的IDEA，，突然啟動到一半，就拋異常了，直接彈窗，報例如以下的異常：

怎樣解決？ 

第一反應。打開Google搜索，輸入例如以下第一行異常進行搜索 

 Fatal error initializing 'com.intellij.psi.stubs.StubIndex'

Google的搜索的效果就不用我多說了。比百度，360等等根本就不是一個層次上的，它們僅僅配提鞋帶，直接在前3條搜索記錄中，就找到了解決的方法，這是是IDEA官方都release的bug，bug列表，大家可以在https://confluence.jetbrains.com/display/IDEADEV/IntelliJ+IDEA+14+138.1283.4+Release+Notes可以找到，在IDEA-125750 (Bug)此條bug號里面，記錄了解決的方法 

除了在官方的bug列表可以解決這個問題，在Google的搜索結果中。另一個stackoverflow問題的鏈接。也能解決這個問題，詳情請點擊此處 

問題原因是：曾經裝的某些插件有問題，於是散仙就回顧了下，在上周裝了一個IDEA的Scala插件，可能是因為這個原因造成的，僅僅要清空windows上c:\Users\<username>\.IntelliJIdea11\config\plugins\這個文件夾。然后 
重新啟動就可以 


請記住我們碼農解決這個問題的兩件法寶神器： 

（1）Google 
（2）Stackoverflow 

神器在手，天下全有。能夠放心的早點下班回去追妹子了。
