具体原因：从网上下载的项目，有几个包在私服找不到，好像就把jar包给删掉了，然后再启动eclipse便报“An internal error occurred during: "reload maven project". eclipse”的错误。找到博主的文章，解决了，用的办法2。

解决办法：
1、删除 .metadata 文件夹可以解决，但需要付出所有项目重新导入。

2、有没有只删除错误项目解决eclipse起来呢？
从日志看 elasticsearch-analysis-pinyin-1.3.0 项目出错。搜索.metadata下所有elasticsearch-analysis-pinyin-1.3.0 的文件和文件夹删除。
如果还没有启动，再从日志查看 org.eclipse.e4.ui.workbench.swt 出错。删除其下面的 workbench.xmi

eclipse 终于起来了。好的项目也加载成功了。
