Java compiler level does not match the version of the installed Java project fac

今天用Eclipse时报这个错误:

Java compiler level does not match the version of the installed Java project facet.

 

问题原因:

Facted Project 中的Java 版本设定与项目的Java编译器的compliance level设定不一致。

解决办法:

把两者设置成相同。

第一步:查看Compiler compliance level

右键Project | Properties | Java Compiler(type filter text输入compiler可快速定位),如下图所示:

Java compiler level does not match the version of the installed Java project fac

根据图中显示可知,Compiler compliance level是6.0(当然您的项目该值很可能不是6.0)

 

第二步:修改Project Facets的Java值,使之和Compiler compliance level相同:

右键Project | Properties | Project Facets(type filter text输入facet可快速定位):

Java compiler level does not match the version of the installed Java project fac

=>选中Java那行

=>点击Modify Project...按钮

Java compiler level does not match the version of the installed Java project fac

 

=>修改Java的值,使之和Compiler compliance level相同(本例为6.0)

 

大功告成!
