升級的Eclipse IDE的Java EE開發

我一直在使用Eclipse IDE的Java EE開發朱諾（4.2 SR1），我已經從Eclipse站點作爲自定義的二進制下載。隨着slowness that haunts Juno，這幾乎無法使用。 eclipse團隊正在修正他們正在宣傳的修補程序，並將其作爲里程碑版本提供。有人可以指導我：升級的Eclipse IDE的Java EE開發

是否可以升級Eclipse IDE for Java EE開發人員從里程碑更新站點獲取相關更改？
如果是的話，如何解決衝突的機制？

我嘗試添加一個update site for Juno milestones並提到here
計算依賴關係之後試圖升級爲Eclipse平臺，它給了細節，爲什麼它不能繼續，我無法破譯。

在此先感謝！
