Ant exec: redirecting standard out but not standard error

Question

I have an exec task whose output I am putting into a property using the outputproperty attribute. The command may print some errors to stderr, I do not want the errors to be included in the output (since the output is being fed into another command) but rather to be printed out to the user. So I am redirecting the output and error into separate properties and echo the error property. It seems kind of a hack to have to echo the error. Is it possible to redirect the output of an exec but leave error on stderr or stdout? I assume it means setting the error attribute to some magical value but I cannot figure out what that value is.

Answer 1

Try removing error or errorproperty attributes and adding logError="true".
