I can't import enums for some reason

Question

In a class I made, I can't seem to import an enum. Eclipse tells me "The import de.game.ground.Constants.Board cannot be resolved." Board is the name of my enum sitting in the class Constants.
What's so weird is that other classes have imported the enum and are using it just fine. But for some reason this one class won't. These classes are all in the same packet. What's up with that? It makes no sense to me that other classes can import it, but I get an error message trying to import it to this class.
After some googling, I tried adding import java.util.*, even though the other classes didn't need it, but that didn't seem to make a difference. I also made sure my "compiler compliance" is set to 1.6. I can't think of anything else to try.

There is no code. The problem is with an import. The code in its entirety would be:
...Of course there is! The entire contents of a .java file is source code.
Here's an example of an SSCCE:
test/Constants.java:
package test;
public class Constants {
    enum Board { A, B, C }
}And a small driver class to test it, test/Main.java:
package test;
import test.Constants.Board;
public class Main {
    public static void main(String[] args){
        Board b = Board.B;
        System.out.println(b);
}Both classes compile just fine and when I run the Main class, 'B' is printed to the console. No errors.
See what I mean with SSCCE: you can copy, paste and compile my code without altering any of it.
