Quite a few things had happened since I first installed Eclipse, like (a) installing / uninstalling plugins (b) upgrading the IDE without correspondingly upgrading the workspace. Since the history has become complex, troubleshooting also got trick. Fresh installation along with importing the code base again, fixed the issue for me.
自从我第一次安装 Eclipse 以来，发生了很多事情，比如 (a) 安装/卸载插件 (b) 升级 IDE 而没有相应地升级工作区。由于历史变得复杂，故障排除也得到了技巧。全新安装并再次导入代码库，为我解决了这个问题。

One thing I did (though I recommend uninstalling and re-installing your plugins first as previously posted by @Rajkumar) is to remove the builder causing the issue. MyProject -> Properties -> Builders ...[Troublesome Builder]... Remove.
我做的一件事（尽管我建议先卸载并重新安装您的插件，如@Rajkumar 之前发布的那样）是删除导致问题的构建器。MyProject -> Properties -> Builders ...[Troublesome Builder]... 删除。
It is a short run solution, you are only circumventing the real issue, but for me, it did what I needed it to for the time being.
这是一个短期的解决方案，你只是在规避真正的问题，但对我来说，它暂时满足了我的需要。

Problem like happens if you have to many resources file like java scripts in your eclipse project. The solution is to remove the java script nature from project facets or disable the java script validation.
如果您的 eclipse 项目中有许多资源文件（如 java 脚本），则会发生类似问题。解决方案是从项目方面删除 java 脚本性质或禁用 java 脚本验证。
