重新指定这个项目使用的JDK.
Eclipse使用哪个JDK和你的项目使用哪个JDK是完全不同的概念..
右键你的项目->属性->Java构建路径->库;在这里你就可以看到你的项目所使用的JDK了.把导入时的那个JDK删除.单击右边的"添加库"按钮.选择"JRE系统库".

选的JRE环境不对，可以尝试Menu » Window » Preferences » Java » Installed JREs选择myeclipse自带的jre环境。

还没运行java文件，eclipse就提示错误The type java.lang.object cannot be resolved，同时运行时也会因为异常而终止。 发现错误 我因为某种原因重新安装了eclipse，却不能运行hiberate框架的项目。当我把项目的library改为jdk8时，项目不会出现原来的异常，但是因为项目内容的原因，jdk版本过低导致项目无法运行。当我尝试将jdk版本换为jdk14和jdk15并重新配置library时，项目还是显示了原来的错误，无论如何都无法运行。 寻找原因
