The AntXMLContext stores the id-object pair in the project instance via
public void configureId(Object element, Attributes attr) {
String id = attr.getValue("id");
if (id != null) {
project.addIdReference(id, element);
}
}
In the Projct class this is stored in a HashMap
/** Map of id references - used for indicating broken build files */
private final HashMap<String, Object> idReferences = new HashMap<>();
public void addIdReference(final String id, final Object value) {
idReferences.put(id, value);
}
But I haven't found a place where this private field is read...
