[aspectj-users] Can't compile basic mixin example

I am probably doing something really dumb here, but I can't seem to compile a basic mixin example under maven.  I am using the example code from AspectJ in Action by Ramnivas Laddad Chapter 5(Like Listing 5.15 in section 5.1.5).
I am packaging a basic Nameable mixin into a jar and that seems to work ok in that even though the files have the .java extension, the class files seem to build the aspect stuff  correctly including the NameableMixin$Impl.

I have ...

1.  src/main/java/ajia/mixin/Entity.java

package ajia.mixin;

public class Entity implements Nameable {
}

2. src/main/java/ajia/mixin/Nameable.java


package ajia.mixin;

public interface Nameable {
	public void setName(String name);
	public String getName();
	
	static aspect Impl {
	private String Nameable.name;
		public void Nameable.setName(String name) {
			this.name = name;
		}
		public String Nameable.getName() {
			return this.name;
		}
	}
}


which yields (as expected) ...

Please let me know if any files in this jar are of interest.
Then I try to use this in another project but the build breaks with 

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] <snipped>src/main/java/<blah blah>/MyMixinTarget.java:[14,7]  MyMixinTarget is not abstract and does not override abstract method setName(java.lang.String) in ajia/mixin/NameableMixin
[INFO] 1 error
[INFO] -------------------------------------------------------------

Not sure why this is happening.  Clearly the ajc is not getting involved where it should, and javac isn't looking for the aspect.  Must all mixin targets be under src/main/aspect?  

The pom.xml for the target project contains(among many other things) :

		<dependency>
			<groupId> ajia.mixin</groupId>
			<artifactId>myaspect</artifactId>
