You can tell Ant to work quietly - with the NoBannerLogger, I think. And you can configure it in the %ant_home%/bin/ant startscript or via setting the environment variable ANT_OPTS. But I don´t think that you have done that.

So test: are you using the right build.xml? It´s the build.xml file in your current directory. You can specify it via -buildfile.

Another mistake could be, that you are using conditional targets - and the conditions fails.

If nothing of this would help you, you can help us by providing the buildfile (one not-running target and the properties should be enough on a hugh buildfile). And a short description what you are doing the directory abc contains build.xml. When I type ant mytarget the output is... My %ANT_HOME% is ... and my %PATH% ... (path is interesting, maybe another Ant installation is started).
