getting null when trying to call custom ant task
hello.
i've written 2 custom ant tasks and am trying to have one (say "ATask")
call the other ("BTask")
i tried the following in ATask (to reference BTask):
someMethod() {
this.project.addDataTypeDefinition("atask",Class.forName("com.test.ATask"));
// also tried without the above line, but the result is the same
ATask task = (ATask)this.project.createTask("atask");
}
however, "task" is turning out to be null.
i'd appreciate any advice. thank you.

actually, i double checked the 2nd custom task that was being called by the
1st. discovered that the 2nd custom task wasn't setting the classpath
correctly. my apologies.
your previous reply did solve the first problem that i was having with the
task. again, thank you.

thank you adam.
it helped, as the "task" instance is no longer null. however, i'm still
getting a null error when i try to call one of the methods of the "task"
instance.
what is the standard way/code for calling another custom task from your own
custom task?
thank you very much.

Shouldn't that be project.addTaskDefinition()?
