無法更新Eclipse WTP，對Eclipse Juno的沖突和不滿意的依賴關系

Question

我嘗試使用“ install new software菜單選項在Eclipse Juno SR2上安裝/更新WTP ，但由於以下錯誤而無法執行操作，

我正在Eclipse上更新WTP以安裝WAS Liberty Profile ，當我嘗試安裝WAS Liberty profile發生以下錯誤，

同時需要WTP庫和匹配同步發行庫，如發現https://wiki.eclipse.org/WTP_FAQ#How_do_I_install_WTP.3F 。 在大多數情況下，同時發布版本庫是最重要的兩個。 實際上，您要安裝的Liberty工具似乎是為Kepler設計的 ，您無法從Juno到Kepler進行就地升級。
