打开xml文件时发生Eclipse问题

由于某些原因，我无法再打开普通xml文件。我做了一些测试，即使使用一个全新的、未经修改的eclipse副本（64位cocoa），我也无法打开xml文件。我所做的是，创建了一个新的java项目，创建了一个新的xml文件。我得到的唯一信息是：

发生了一个错误。有关详细信息，请参阅错误日志。 无法初始化类org.eclipse.m2e.editor.xml.PomContentAssistProcessor

你知道原因是什么吗

更新：

我仔细查看了错误日志，显示了以下内容：

java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.m2e.editor.xml.PomContentAssistProcessor

不知何故，依赖性缺失了，但我不知道如何解决它。我试图重新安装m2e，但它只是告诉我它已经安装，并且只会显示在已安装的应用程序中

这是完整的stacktrace，也许有人会建议下一步该怎么做

如果新副本不起作用，这意味着工作区或项目元数据已损坏。尝试创建一个新的工作区

---

问题似乎与m2eclipse有关-eclipse正在尝试加载pom编辑器，但失败。您也可以尝试安装/更新m2eclipse。

与indigo有相同的问题，只需打开原始下载的zip并覆盖插件目录中以

org.eclipse.m2e.*

开头的所有jar文件，问题就消失了

尝试打开XML或Java文件时出现类似问题：

org/eclipse/wst/xml/ui/internal/tabletree/XMLMultiPageEditorPart

无法打开xml或java文件

日食开普勒4.3。IDE被winturds系统重启杀死。
随后，启动IDE，出现错误

我聪明的解决方案是：通过文件退出IDE：退出并重新启动IDE。这种情况以前发生过

您的里程数可能会有所不同。

我通过使用-clean参数启动Eclipse（开普勒）实现了这一点

"d:\eclipse\eclipse.exe -clean"

---

当我尝试这一点时，eclipse比平常花了更多的时间出现，因为它将清理和重新加载插件。

luna也有同样的问题。重新生成对我有用的库插件依赖项。

不知何故，我无法解决它。似乎我正在进行最新的更新，eclipse构建id:20110615-0604和m2e 1.0.0.20110607-2117。新的eclipse+新的工作区不可能不工作。你缓存了一些东西，我删除了所有文件，包括~/Library/Caches/org.eclipse。。然后我下载了一个新的副本，创建了一个全新的工作区，但消息是一样的。在那之后，我尝试用-clean重新启动eclipse，没有结果。还有其他想法吗？你已经看到了没有m2eclipse的Eclipse的新副本吗？这是很久以前的事了，但是一次干净的重新安装解决了这个问题。谢谢你的评论，但这篇文章是在2011年发布的，而且Vitali Bichov的评论已经解决了；）
