No there isn't, but there's always a way! How about creating a
BuildListener? When targetFinished(...) is called, you query the
BuildEvent object passed in for the build exception using
getException(). If there was an exception, you'd get a non-null value.
Otherwise you get null.
When you get an exception for a task, take the task name and put it in
a hashtable. Then you could create another method, callable from your
scripting code, to query if a task has failed. I know it's a bit of a
stretch, but it should be doable.
