現象： eclipse的preferences裡面需要儲存密碼，儲存報錯Could Not Accept ChangesThe currrently displayed page contains invalid values或者是儲存後，再次開啟preferences視窗，提示The currrently displayed page contains invalid values

環境：

Windows 2008

remote windows terminal 遠端桌面訪問

clipse Juno

可能有多人用一個帳號登入Windows OS。

排錯：

檢視eclipse日誌，檔案%workspace%\.metadata\.log看到如下內容：!ENTRY org.eclipse.equinox.security 4 0 2014-04-26 01:00:28.919!MESSAGE Secure storage was unable to retrieve the master password. If secure storage was created using a different Windows account, you'll have to switch back to that account. Alternatively, you can use the password recovery, or delete and re-create secure storage.!STACK 0org.eclipse.equinox.security.storage.StorageException: Secure storage was unable to retrieve the master password. If secure storage was created using a different Windows account, you'll have to switch back to that account. Alternatively, you can use the password recovery, or delete and re-create secure storage.at org.eclipse.equinox.internal.security.win32.WinCrypto.getPassword(WinCrypto.java:62)

解決辦法：

開啟eclipse preferences，選擇General->Security->Secure Storage，去掉Windows Integration，保留UI Prompt，確定，關閉Preferences視窗。

注意如果多個人在這臺機器啟動了 eclipse，操作前請其他人退出eclipse。

不方便的地方：

eclipse在儲存讀取口令等敏感資料到preferences的時候，可能會提示使用者設定/填寫口令。

首次設定口令的時候會提示是否需要提供恢復口令的手段，可以不提供，取消即可。
