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

今天将MyEclipse升级到 9.1 后,打开原来的工作空间,原来所有的项目都前面都显示了一个小叉叉,代码中却没有任何错误。于从 problems 视图中查看错误信息,错误信息的“Description”显示:
Java compiler level does not match the version of the installed Java project facet.
之前没有碰到过这个错误,于是 google 了一番,果不其然,很多人都碰到了同样的问题,解决方案有如下两种:
方案1. 在项目名称处点击鼠标右键-->属性,打开项目属性对话框,找到 MyEclipse-->Project Facets,将此处的 java 版本设置为与项目编译级别相同。
方案2. 在“工程/.settings/”目录下找到名为 org.eclipse.wst.common.project.facet.core.xml 的文件,将该文件中 <installed facet="java" version="x.x"/> 处的 version 值修改为与项目编译级别相同,保存该文件,然后刷新工程即可。
