Java compiler level does not match the version of the installed java project facet错误的解决

因工作的关系,Eclipse开发的Java项目拷来拷去,有时候会报一个很奇怪的错误。明明源码一模一样,为什么项目复制到另一台机器上,就会报“java compiler level does not match the version of the installed java project facet”错误呢?

如图所示:

其实要解决也很简单,在资源管理器下,找到项目所在的目录,在.settings子目录里面,用文本编辑器打开org.eclipse.wst.common.project.facet.core.xml配置文件,如图所示:

修改红色画线部分,让它与项目的编译器版本设置保持一致即可。

要查看项目的编译器版本设置,在Eclipse环境中,鼠标右键选择项目,点击Properties,选择Java Compiler,可以在窗口右边看到编译器版本,如图所示:
