这很烦人，因为我需要完成一项重要的工作。 我搜索了互联网，但似乎没有太多关于这个问题。

有什么想法吗？ 谢谢你的帮助

Answer 1

重新安装肯定会起作用，但对我来说这似乎是一个很大的障碍。

我发现为我工作的是找到其中一个org.eclipse.e4.core*包。他们很可能会在plugins目录中。然后逐个删除它们并重新尝试加载Eclipse。 Eclipse启动后，您可以根据需要重新安装特定插件。但至少你会保留所有的项目和其他设置。

Answer 2

如果已安装Eclipse，请转到：“主目录” .p2 \ pool \ plugins 如果尚未安装，请转到：plugins目录

就我而言，我有org.eclipse.e4.core.contexts的三个版本：

这三个软件包中的三个都在artifacts.xml上引用了，其中两个软件包在feature.xml中也引用了org.eclipse.e4.rcp（两个不同版本）软件包。

我只是删除了最旧的罐子，并保留了最新的org.eclipse.e4.core.contexts_1.8.100 Eclipse复活了= D

P.S。 ：加分！ Eclipse突然运行得更快

Answer 3

我遇到了同样的问题。

感谢ilya1725，我发现/plugins/org.eclipse.e4.core.contexts_1.3.100.v20140407-1019导致了这一点。在删除之后，eclipse又重新启动而无需重新安装。
