Getting task info in build listener
While playing with build listeners, I noticed that in the taskStarted
method I can query event.getTask(), but it will always return an
UnknownElement class. What is the appropriate way to get a the real task?
E.g.,
public void taskStarted(BuildEvent event) {
Task t = event.getTask();
printMessage("TASK " + t.getTaskName() + " STARTED", ...);
// This will always print UnknownElement.
printMessage("TASK CLASS " + t.getClass().getName(), ...);
// So this fails...
if ( t instanceof SomeSpecialTask ) ...
}
Thanks,
Johan

Hi Matt,
thanks for the pointer ! BuidListener works great with
event.getPriority() . I am able to output debug info now

The debuglevel is set per listener rather than on the
whole Project... so you would attach a BuildListener
set up as you need it. You should be able to
configure an oata.DefaultLogger for your purposes.

How to set ant debugging on from java api call?
Posted by sudip barat <sb...@cisco.com>.
Hi
I am invoking ant from my java program and writing the output in a file . I
want to know which property I need to set in project or which api call I
need to make to turn on the debug (equivalent to running ant -debug from
command prompt )? Or is there a project level property I can set in my
build.xml to make it that way ?
Thx
sb

It cannot be done too easily at the moment.
The taskStarted method is called indirectly from Task.perform(), before the
unknown element task gets "configured". "configured" means that
the implemention object associated with the unknown element gets created
and initialized.
One can work around this by doing:
public void taskStarted(BuildEvent event) {
Task t = event.getTask();
if (t instanceof UnknownElement) {
UnknownElement u = (UnknownElement) t;
u.maybeConfigure();
Task n = u.getTask();
if (n != null) {
t = n;
}
}
System.out.println("TASK " + t.getTaskName() + " STARTED");
// This will always print UnknownElement.
System.out.println("TASK CLASS " + t.getClass().getName());
}
but this does have the side-effect of "configuring" the object twice.
This has bad consequences.
