先说我自己的原因 昨天 使用maven 加载jar包 因为是新的 要更新 ，时间太长了 等不了 ，就把它关了 ，项目也想删除， 但是 删除的过程中 给我显示一个 加载的长条 等了10多分钟都没有删除，一直加载 。。一起之下 强行将eclipse关闭， 然后 第二天 却打不开eclipse 报错 An internal error occurred during: "reload maven project". java.lang.NullPointerException 然后 我就把 workspace 下的 该 项目删除 还是包原来的 错误
项目是 基于SpringBoot的
说解决方法 因为打不开eclipse 所以要去 log 日志下 查看 原因 地址 workspace.metadata.log
错误信息如下

说明 系统 找不到 该 pom.xml 文件
然后 去 workspace.metadata.pluginsorg.eclipse.e4.workbench 找到 workbench.xmi 文件
然后 你 可以 按 Ctrl+F 搜索 该 文件 下的 导致你出错的 项目的 名字 我的是 springBoot01 因为已经不存在了 所以用 springboot 代替 文件工具用的是 notepad++
找到后 删除 该 <sharedElements> </sharedElements> 所有文件 就好了
有的 文件的 显示 方式 可能不一样 你可以 根据 该项目 上面 特有的 xmi:id 编码 然后分别搜索 删除 带有 该编码下的文件 就行了
