Subject Re: Java task - output defaulting stdout
Date Tue, 14 Mar 2006 12:50:03 GMT
Hi  Petar,

Do you mean that omitting the output attribute of the java task is
equivalent to setting it to "console"?
Indeed, I want to take advantage of Ant properties being immutable.

However, I did not know the value to use to get default behavior when the
user does not set any.
I am going to try with "console" as you suggested.

Thank you,
Frederic
