I was able to run the build file successfully using Ant 1.6.2 with jsch =
version 0.1.16. This is not a known problem with sshexec. It may be a =
problem with jsch. What version of jsch are you using? When I use jsch =
0.1.20 is see the same problem with the output, but I still see BUILD =
SUCCESSFUL.
