Hmm. I'm using 1.3.0..... I wrote a little set of test classes, etc.
to figure out what worked. I saw errors on all my classes when I first
tried the _expression_ that I said doesn't work. ;) The PC with two
"withins" gave me the error on just the class with the annotation but
not the interface.
Here is the code I used:
== experiments.parents.RequireInterface.aj ==
package experiments.parents;
public aspect RequireInterface {
declare error:
within (@MyAnnotation experiments.parents.*) &&
!within (experiments.parents.MyInterface+): "Must implement MyInterface";
/**
* Alternative: Force all classes with the annotation to implement
the interface.
* Any classes that don't implement the interfaces methods will not compile.
*/
// declare parents: (@MyAnnotation *) implements MyInterface;
}
== experiments.parents.MyAnnotation.java ==
package experiments.parents;
public @interface MyAnnotation {}
== experiments.parents.MyInterface.java ==
package experiments.parents;
public interface MyInterface {
int doit ();
}
== experiments.parents.HasInterfaceImpl.java ==
package experiments.parents;
// Class that implements the required interface
@MyAnnotation
public class HasInterfaceImpl implements MyInterface {
public int doit() { return 0; }
}
== experiments.parents.MissingInterfaceImpl.java ==
package experiments.parents;
// Class that doesn't implements the required interface
@MyAnnotation
public class MissingInterfaceImpl {
//...
}
When I build, the only error is on the last class.

Thanks, but it doesn't seem to work. It creates multiple error markers in
Eclipse, which don't seem logical or consistent.
Have I stumpled on a bug in the AJDT 1.3?
