Eclipse 4和RCP

Question

我試圖從vogella網站上做eclipse tutorial。我收到以下錯誤，當我嘗試創建一個新的應用程序：

我也有這個錯誤：

Resource '/com.example.e4.rcp.wizard/plugin.xml' already exists 

我使用Eclipse RCP的和RAP開發人員版本：朱諾服務發佈1 建立ID：20120920-0800在Windows 7 64位，

有人可以告訴我，問題在哪裏？

Answer 1

可能重複：Here

嘗試按照第二個建議：

Create new Workspace

..as你有插件錯誤太多。
