Import the missing classes so that the unqualified types can be used in the program
导入缺少的类，以便程序中可以使用不合格的类型

This error occurs because you have used some classes from some other package and Compiler is not able to resolve those dependenciesbecause of missing imports.
出现此错误是因为您使用了其他包中的某些类，并且 Compiler由于缺少导入而无法解析这些依赖项。
Use Ctrl+Shift+Oto Auto import all the required dependencies. Or use manual import as suggested by @Reimeus.
使用Ctrl+ Shift+O为自动导入所有需要的依赖。或者按照@Reimeus 的建议使用手动导入。
