Ganymed
SSH-2 for Java是一個純Java實現的SHH2庫，官網爲http://www.ganymed.ethz.ch/ssh2/，最新的更新時間爲2006年10月，在用之前，請仔細看一下FAQ，真的能避免很多很多問題
在google上找到的ganymed-ssh2的官網是http://www.ganymed.ethz.ch/ssh2/，進去看官網的英文簡介可以看到該網站已經不維護該項目，並已經遷移到http://www.cleondris.ch/，在這個網站點擊右上角的Contact，再點擊open source就可以看到這個項目的新家,http://www.cleondris.ch/opensource/ssh2/,上面簡單介紹了該項目能遠程連接上遠程機器，支持命令模式和shell模式，本地和遠程端口轉發，沒有任何JCE依賴等,最後特別指出這個項目是爲瑞士蘇黎世的一個項目所創建。下面提供了2010-08-23發佈的ganymed-ssh2-build251beta1.zip可供下載使用，下面還有在線文檔和FAQ供開發者參考。
JSch
採用java編寫，使用ssh來操作遠程服務器。JSch 是SSH2的一個純Java實現。它允許你連接到一個sshd 服務器，支持文件的上傳和下載，支持在遠程機上執行shell命令、shell腳本、重啓等操作。
但是這個類庫偏向底層，僅是ssh2的實現，連文件夾的上傳下載都不支持，並不是針對自動化部署的，編寫的代碼比較長，上手和實際使用起來不太方便，所以要對其進行必要的封裝，比如封裝連接的獲取釋放、文件夾和文件的拷貝、遠程命令的執行等。
sshxcute
sshxcute 框架是對JSch 的簡單封裝，提供了更爲便捷的 API 接口，提供了更加靈活實用的功能，從而可以讓開發人員更加得心應手的使用。sshxcute 是一個框架，它允許工程師利用 Java 代碼通過 SSH 連接遠程執行 Linux/UNIX 系統上的命令或者腳本，這種方式不管是針對軟件測試還是系統部署，都簡化了自動化測試與系統環境部署的步驟。
但是它的封裝比較簡單，功能比較弱，只有上傳和執行命令或腳本的功能。
包裝Ganymed。實現了文件的上傳下載，文件夾的上傳，遠程執行命令，執行本地命令等基礎API：
