报Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedClassVersionError怎么解决

Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedClassVersionError: com/java/util/DbUtil has been compiled by a more recent version of the Java Runtime (class file version 60.0), this version of the Java Runtime only recognizes class file versions up to 52.0
报了这个错误怎么办啊
我把这个项目在更高版本的eclipse上运行之后再运行就不行了
没有遇过这种情况需要重装eclipse吗
