some characters cannot be mapped using "ISO-8859-1" character encoding.
Either change the encoding or remove the characters which are not supported
by the "ISO-8859-1" character encoding.
解決辦法:
方案一: 菜單->Window->Preferences->General->Content Types->Text->Java Properties File設置Default encoding,把ISO-8859-1改爲UTF-8 然後update.
