如何在沒有工作空間和其他Eclipse默認功能的情況下創建RCP項目？

Question

如何在沒有工作空間和其他Eclipse默認功能的情況下創建RCP項目？

每次創建Eclipse RCP項目時，它都會在單獨的工作區中運行，在左側顯示Package Explorer，允許創建項目等。

是否有可能創建獨立的應用程序，如XMind，它只是打開某些類型的文件幷包含某些類型的視圖？

UPDATE

例如，有一個激爽樣品只是在Eclipse的幫助。它旨在Eclipse下運行，但包含主要：

如何編譯？如果我把它放到java項目中，它沒有大量的Eclipse庫。但是，如果我創建插件項目，我看不到插入主要方法的地方。

Answer 1

要獲得絕對最小的RCP代碼，請執行File/New Project並選擇Plug-in Project。在嚮導的第二步取消選擇This plug-in will make contributions to the UI並選擇Yes代替Would you like to create a 3.x rich client application。嚮導的最後一步將有一個Headless Hello RCP，它爲RCP創建絕對最小代碼。

如果您離開This plug-in will make contributions to the UI選中某些模板以創建包含視圖的RCP等等。

以上是適用於Eclipse 3.x樣式的RCP，適用於Eclipse 4純e4 RCP在新建項目嚮導中使用Eclipse 4/Eclipse 4 Application Project。
