3.解决方案：

①.右键工程->Build Path -> Configure Build Path ， 在 Libraries 选项下，会发现有个出错的jre Libraries，将其Remove掉。



②.然后右击该项目 - Build Path - Add Library， 选择JRE System Library,选择添加的版本，之后一路ok即可。



4.小插曲：我的eclipse里面开始没有找到build path，很是头大，后来自己多次尝试，有两种方法可以找到

①.在右上角有各种模式可以选择，选择java之后，右键该项目就有build path选项了，之后操作同上。

②.在javaEE模式下也可以使用build path，截图不是javaEE模式（别误会）



右键JRE就可以看到build path选项，其他操作同上
