Eclipse无法启动报An internal error occurred during: "reload maven project". java.lang.NullPointerException

     

    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
