Eclipse 更新时出現 Error retrieving "feature.xml". [error in opening zip file] 的解决方法

原因為直接 Copy 套件到 Eclipse 目錄下時覆蓋到了 site.xml 檔所造成，將此檔案刪除後，重開 Eclipse 即可。

Subclipse 設定 Http Proxy [XP]

在以下目錄尋找 servers 設定檔

C:\Documents and Settings\[username]\Application Data\Subversion

其中 [username] 為使用者的XP帳號名稱

在 servers 設定檔新增或修改如下設定

[globals]
http-proxy-host = proxy1.some-domain-name.com
http-proxy-port = 80
http-proxy-username = blah
http-proxy-password = doubleblah

http-proxy-host 為 IP Address

http-proxy-port 為網路接口

http-proxy-username 為帳號

http-proxy-password 為密碼

修改完後儲存即可
