：JUNO庫，我發現很多鏈接，我試圖下載所有這些，但在下載期間，我得到一個錯誤說「安裝軟件」遇到了問題，同時收集物品被安裝時發生錯誤

我該怎麼做才能解決這個問題，我應該精確地說我下載了一個離線版本，但我不知道如何整合它，請向我澄清一些事情。

Answer 1

您應該下載OEPE ... Oracle Enterprise Pack for Eclipse。他們實際上有一個包含Eclipse的完整下載。只需谷歌Oracle OEPE，你會發現它。

Answer 2

此問題通常意味着從更新站點下載罐子時發生了一些問題。請注意，這也意味着您已經通過確定要安裝哪些jar的第一階段（這需要通過網絡連接來確定應該安裝的內容）。

這意味着幾件事情之一：

1. 你的防火牆阻止罐的下載。轉到首選項 - >常規 - <網絡連接解決此問題
2. 您在安裝過程中部分中斷了連接3。
3. 您的本地更新站點內容緩存已舊或損壞。轉到首選項 - >安裝/更新 - >可用軟件站點。選擇所有網站，然後點擊「重新加載」並重試。
