Getting 6 errors of type “cannot find symbol” every time it compiles Java

This has happened on two of three workspaces. I theorize that it has something to do with file path cause the two broken ones are in a in the same folder, but not the working ones’ folder. Anyways, it does this whenever there is an entity at all. I can't do anything when this happens. Try to run client? COMPILER ERROR. Try to BUILD? COMPILER ERROR. It is so frustrating. I can’t give much more, but I really need a fix.
