The type java.lang.Object cannot be resolved解决方法

今天在用Eclipse导入其它项目时，一直出现这个问题，然后就开始找解决的方法。
1.The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project
2.The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files

解决办法：
1.将JRE先remove掉，然后重新引入JRE即可。
(Project->properties->Java Bulid Path->Libraries->Add Librarie

选取：Jre System Librarie )
