I use the clearcase-ccupdate task with Rational ClearCase LT 2003.06.00. Our development tree is fairly large and updates on the view produce many lines of output to the console, one line for each subdirectory at minimum. The separately generated log file records all changes, so this output serves no purpose. I am seeking a way to suppress the display of the update's output in ant.
If you add such a feature, we can add it to the code. I dont think any of the ant developers actively use clearcase these days, which prevents any of us from adding the feature (We'd never be able to test it). Having used CC in the past, please accept my sympathy :)
