IntelliJ不反映Maven依赖项

我最近更新了我的 IntelliJ ，我遇到了一个问题，它在类路径中显示导入语句不存在，尽管项目构建正常，但是从命令行mvn clean [install | verify] ，软件实际可行。因此依赖关系肯定存在，但IDE似乎有一个与pom文件同步的错误。我试过 Maven - >多次重新导入，但没有成功。

I recently updated my IntelliJ and I am having a problem with it showing import statements as nonexistent in the classpath despite the project building fine by doing mvn clean [install|verify] from the command line and the software actually works. So the dependencies are certainly there but the IDE seems to have a bug synchronizing against the pom file. I have tried to Maven --> Reimport multiple times, without success.

考虑到我最近更新了IntelliJ（该版本截至2017年7月15日），是否可以是一个新引入的错误，是否有解决方法？

Considering that I recently updated IntelliJ (the version is as of 7/15/2017), could this be a newly introduced bug and is there a workaround?
