[aspectj-users] Mixin not recognized

["Leyzerzon, Simeon " <simeon.leyzerzon@xxxxxxxx>]

I'm trying to create a mixin inside an AJ project in MyEclipse:

public interface IDaoMixin {

        public static aspect Impl {
                ....
        }

        public void setJdbcTemplate(JdbcTemplate template);

}

and it gives me the following:

Multiple markers at this line
        - Syntax error on token "aspect", class
         expected
        - aspect cannot be resolved to a type
        - The interface IDaoMixin cannot define an
         initializer

What ccould be a problem here?  What's interesting, is that the Problems view in Eclipse doesn't register a problem, it only appears inside the editor.

Here's the .project file:
