maven antrun ssh or scp hides the output

Question

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:

Update: (16/3/16 8:11 GMT)

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:

        <execution>

            <goals>
                <goal>run</goal>
            </goals>
            <phase>process-sources</phase>
            <configuration>
                <target>
                    <echo message="Pushing to host..." />
                    <sshexec host="hostname" username="user" trust="true" 
                        password="pass" failonerror="true"  
                        command="mkdir -p /home/user/test/test"/> 
                    <scp trust="yes"
                        file="some-file"
                        todir="user:pass@hostname:/path/to/some-file" 
                        />
                </target>
            </configuration>
        </execution>
    </executions>

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.
