Answer 1

我做过的一件事（虽然我建议首先卸载并重新安装插件，如先前由@Rajkumar发布的）是删除导致问题的构建器。 MyProject - ＆gt;属性 - ＆gt;建筑商...... [麻烦的建造者] ......删除。

这是一个短期解决方案，你只是在规避真正的问题，但对我来说，它确实是我现在所需要的。

Answer 2

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而不相应地升级工作区。由于历史变得复杂，故障排除也变得棘手。全新安装以及再次导入代码库，为我解决了问题。

Answer 3

如果你的eclipse项目中有许多像java脚本这样的资源文件会发生类似的问题。解决方案是从项目构面中删除java脚本性质或禁用java脚本验证。

从插件调用代码时出现问题：“org.eclipse.core.resources”
