Ant task with custom nested types
I'm following the Apache Ant documentation for "Writing Your Own Task" but I can't get it to work with an interface different than Condition:
In CustomTask.java:
public final class CustomTask extends Task {
public void add(final Type type) {
log("Got: " + type + " with value: " + type.getValue());
}
@Override
public void execute() {
log("Executing custom task...");
}
}
In Type.java:
public interface Type {
String getValue();
void setValue(final String value);
}
In DefaultType.java:
public class DefaultType implements Type {
private String value;
@Override
public String getValue() {
return value;
}
@Override
public void setValue(final String value) {
this.value = value;
}
}
And in the build.xml where I want to use them:
<taskdef name="custom-task" classname="CustomTask" classpathref="run_classpath" />
<typedef name="default-type" classname="DefaultType" classpathref="run_classpath" />
<target name="custom">
<custom-task>
<default-type value="Hello world!" />
</custom-task>
</target>
But I get the following error:
.../build.xml:37: custom-task doesn't support the nested "default-type" element.
The crazy thing here is, if I make DefaultType implement the org.apache.tools.ant.taskdefs.condition.Condition interface (as in the example from the documentation) and add to the CustomTask class the following method:
public void add(final Condition condition) {
log("Got: " + condition);
}
It works: (!?!?!)
custom:
[custom-task] Got: DefaultType@5a39699c
[custom-task] Executing custom task...
I don't understand, what is special about the org.apache.tools.ant.taskdefs.condition.Condition interface that it only works with it?
Thanks for the help.

It seems the issue goes away if you add the loaderref property to both definitions with the same value (it seems it can be anything, this is not clear in the documentation):
<taskdef
name="custom-task"
classname="CustomTask"
classpathref="run_classpath"
loaderref="my_loader" />
<typedef
name="default-type"
classname="DefaultType"
classpathref="run_classpath"
loaderref="my_loader" />
