FWIW: "id" is some kind of _magic_ attribute dealt with at parsing time in
the project helper impl. I naively thought it was a regular 'attribute' with
a setter... --DD
package org.apache.tools.ant.helper;
public class ProjectHelperImpl extends ProjectHelper {
<snip/>
/**
* Scans an attribute list for the <code>id</code> attribute and
* stores a reference to the target object in the project if an
* id is found.
* <p>
* This method was moved out of the configure method to allow
* it to be executed at parse time.
*
* @see #configure(Object,AttributeList,Project)
*/
private void configureId(Object target, AttributeList attr) {
String id = attr.getValue("id");
if (id != null) {
project.addReference(id, target);
}
}
}

OK, I think I've got it this time:
String idname = "myid";
Path path = new Path(getProject(), classpath);
getProject().addReference(idname, path);
Let me know. --DD

There is no "setId()" method for org.apache.tools.ant.types.Path.
