Question

我在网上和这里研究过这个死神。我已经尝试过清理项目和 eclipse -clean 以及其他一些东西，但到目前为止，还没有快乐。我也无法将它与任何事件联系在一起;它似乎刚刚开始发生。这已经是Eclipse Oxygen的稳定使用已有一段时间了。如果我切换到Mars.1或Neon，我会得到相同的结果，让我觉得这是一个工作空间问题，但我不知道Eclipse的“胆量”很好进入并开始捣乱。老实说，这看起来像一个腐败的罐子或东西给我。

当我在Project Explorer中展开我的一个C ++项目时，错误日志中的所有内容都会崩溃。如果您不介意不断发生的“Problem Ascurred”对话框通知您java.lang.NullPointerException，那么一切似乎都有效。唯一可见的错误是我的C ++文件旁边不再有图标。右键单击 Git存储库选项卡中的某些元素也会导致问题。

我没有安装任何新东西。没有插件，编辑器等我会继续打败这个小子，但在此期间，这里有一个示例错误日志条目：

Answer 1

这看起来像Eclipse bug 502514。

如果我正确阅读了错误，编辑注册表就会因市场代码中的问题而被破坏。浏览首选项中的文件关联可能会修复它（错误报告中的更多详细信息）。

该错误在Eclipse Neon.2（4.6.2）中标记为已修复。修复可能在最近发布的Eclipse Oxygen Milestone 3（4.7M3）

中

Eclipse Oxygen＆amp; org.eclipse.jface给出了NullPointerException对话框
