maven antrun ssh or scp hides the output

问题:

I want to run an ssh & scp commands using antrun in mvn.
the ssh & scp commands runs correctly, and the plugins that declared inthe next phases - run. but the output of all commands after the ssh/scp - isn't written to any output!

What is the problem?!

here is my pom.xml:

the file jsch-0.1.29.jar was created in the target dir, but the output is:

scp - works fine.
sshexec with a file script (commandResource="[file]") - works fine.
sshexec with a single command (command="[command]") - causes problem, as mention above.

Give it a try with newer versions of JSCH dependencies (1.8.4 for ant-jsch and 0.1.53 for jsch, each with different group ids). It fixed the problem on my side:

Thank you very much. After two long evenings I found the solution.

I had the latest version of ant and not org.apache.ant which was changed at version 1.6 So latest version is today 1.10.1 and it works very well.
