我的Eclipse陷入僵局，因此我關閉了它（通常，我沒有發送任何殺死信號或任何東西，編輯器竊聽，但菜單仍在工作，所以我只是從菜單中退出）。插件org.python.pydev無法加載類org.python.pydev.editor.PyEdit
當我重新打開日食但我得到了這個問題：
Plug-in org.python.pydev was unable to load class org.python.pydev.editor.PyEdit.
我使用Eclipse開普勒2版版本ID：20140224-0627
與Java 8和
的PyDev 4.5.4.20160129223
我試過重建工作區，清理工作區，重新啓動它，但沒有任何工作。我現在已經更新PyDev到PyDev 5，它仍然給我同樣的錯誤。
此外，在Package Explorer無法加載或者並給出了錯誤：
Plug-in org.eclipse.jdt.ui was unable to load class org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart.
任何想法？
確切回溯是：
