Eclipse的：異常切換升級後的視角來朱諾

Question

我最近從靛藍升級到朱諾，雖然到目前爲止一切似乎是工作好，我每次我切換視角時得到一個例外：

An error has occurred. See error log for more details. org.eclipse.ui.internal.WorkbenchPage.findPerspective(Lorg/eclipse/ui/IPerspectiveDescriptor;)Lorg/eclipse/ui/internal/Perspective;

在日誌中有以下內容：

我發現the report of a similar problem，在那裏它被建議用-clean選項應該把事情恢復正常重新啓動。在我的情況下，它並沒有解決。

任何有關如何解決這個問題的線索都是值得歡迎的。謝謝。

更新：我想升級到開普勒，但我得到這個錯誤：

編輯：噢，等等。你的問題有點不清楚。您是否遇到過Juno IDE或您自己的Eclipse項目？如果是IDE，請重新安裝。如果是你自己的項目，請繼續閱讀。

首先，您需要將核心依賴關係切換到新的目標平臺。

轉到的plugin.xml - >依賴 - >刪除org.eclipse.ui和org.eclipse.core.runtime（我猜你這些，你有任何更多。 eclipse的插件，請務必將其刪除），然後再次添加它們！其次，請記住在調試配置窗口中包含所有必需的插件。

去那裏，去插件，取消目標平臺，單擊添加所需的插件，單擊驗證，然後應用並運行它。
