Eclipse：Eclipse Installer: can not initialize cryptographic mechanism---Eclipse安裝程式:不能初始化加密機制的問題

Eclipse：Eclipse Installer: can not initialize cryptographic mechanism—Eclipse安裝程式:不能初始化加密機制的問題

程式猿、重裝系統很正常，昨天因為系統盤崩了被我重裝了一次系統， 之後再一系列配置之後我打開我的eclipse,當頭就報一個錯，說什麼内部錯誤、等等，我就尋思着 是不是重裝系統的緣故，我就直接去官網重新下載下傳了一個，結果在下載下傳好之後打開安裝程式的時 候又再次給我報一個錯

Eclipse Installer: can not initialize cryptographic mechanism
           

告訴我Eclipse安裝程式:不能初始化加密機制、當時就納悶了，點了×之後又出現

之後點選：：This is an emergency update: Contiune?、、彈出

Could not initialize class sun.security.ssl.SSLContextImpl$DefaultSSLContext
           

無法初始化類sun.security.ssl. sslcontext $DefaultSSLContext

最後彈出

其實這個時候已經很明顯了是jdk的問題；隻怪我大意，一直以為是不是出啥bug了，又去下了兩次Eclipse，結果還是這個錯，網上也沒對應的解決方法，後面又想了直接下載下傳壓縮包，不就行了嗎?—結果可想而知，項目用不了，編譯出錯，其實種種迹象指向了jdk，當時哪裡想到這次用的卻是我在網上下載下傳的一個新版jdk，解壓之後直接配置環境變量就以為就行，看都沒看jdk内容，當時用cmd還能檢視版本，也不會以為是路徑的問題，

**

一直到我今天我再次建項目編譯測試的時候，我去jdk瞅了一眼，媽耶那個大神的jdk連jre都沒有，難怪這幾天怪事多解決方發重新下載下傳一個新的完整的jdk，重新配置環境，JAVA_HOME，最後我去試了試下載下傳eclipse安裝ok解決不會報錯。*
