异常分析：
Eclipse记忆密码时，会在“C:\Users\……\.eclipse\org.eclipse.equinox.security”目录下生成“secure_storage”文件。
“secure_storage”文件中保存有“master password”以及与各Eclipse插件相对应的“业务密码”，记忆“业务密码”之前需要验证“master password”的正确性。第一条异常信息“No password provided”是在输入了“业务密码”后，并选择记忆密码保存时出现的，所以其应该表示的是没有提供“master password”或在使用默认的“master password”（Windows Integration）出现故障。
解决办法01：
打开eclipse preferences，选择General->Security->Secure Storage，去掉Windows Integration，保留UI Prompt，确定，关闭Preferences窗口。
然后重新输入“业务密码”，选择记忆密码并保存。这时会出现以下界面：
master password
是否设置密码找回
密码找回问题设置
注意：每次重启Eclipse均需要输入一次master password;
解决方法02:
前面提到过“secure_storage”文件，当出现相应异常信息时，亦可尝试将此文件删除，重新输入各插件“业务密码”来完成记忆密码的功能。注意：需要选中Windows Integration。
