Your .metadata probably got corrupted.

I solved my build error in eclipse juno by restoring my eclipse work space. Reason being, the .metadata was corrupted so whenever i could try to build the project it could sometimes fail. Therefore you have to backup yr projects in a folder outside the main work space then deleted the whole work space folder. Restart eclipse and create a new work space and import yr projects into yr new work space. Everything will work normally after that.

我通过恢复 eclipse 工作空间解决了 eclipse juno 中的构建错误。原因是 .metadata 已损坏，因此每当我尝试构建项目时，它有时都会失败。因此，您必须在主工作空间之外的文件夹中备份 yr 项目，然后删除整个工作空间文件夹。重新启动 eclipse 并创建一个新的工作空间并将 yr 项目导入到 yr 新工作空间中。之后一切都会正常工作。

Thanks Umark

This kind of problem is very rare but we have the solution, If you are using gradle or maven then first close your project and delete from eclipse (remember don't delete from disk), then delete the files and directories from your project:

这种问题很少见，但我们有解决方案，如果您使用的是 gradle 或 maven，那么首先关闭您的项目并从 eclipse 中删除（记住不要从磁盘中删除），然后从您的项目中删除文件和目录：

1. .settings/
2. .project
3. .classpath
4. .gradle/

1. .设置/
2. 。项目
3. .classpath
4. .gradle/

then reimport the project in eclipse and you are done. you will no longer face the error like "Errors running builder 'Java Builder '"

然后在eclipse中重新导入项目，你就完成了。您将不再面临像“错误运行建设者的Java生成器“错误”

I resolved this by reverting the .cproject file in my project folder to an older version (which was created when I setup the project for the first time)

我通过将项目文件夹中的 .cproject 文件恢复到旧版本（这是我第一次设置项目时创建的）解决了这个问题
