Ant SCP task not working - where as I am able to scp using cygwin

Please provide your expert option for a issue I am facing at work..

1. Ant SCP task not working - where as I am able to scp using cygwin.

2. Local Environment: windows 7 64 bit, Jdk 1.6.0.24, Ant-1.8.2 (with ant optional dependencies fetched), maven 2 (usign ant run plugin), jsch-0.1.44 Remote Environment: VM Labmanager 4.0, Windows Server 2008 - R2, SSH-2.0-OpenSSH_5.8, JDK 1.6.0.24

3. I have set password authetication to yes and restarted sshd on remote host.

4. Maven goal is as follows. (btw, I executed same ANT target as well, so Ant and Maven are giving the same result with jsch-0.1.44 and jsch-0.1.42 )

   <plugin>
   <artifactId>maven-antrun-plugin</artifactId>
   <version>1.6</version>
   <executions>
       <execution>

               <target>
                   <scp file="readme.txt"  todir="devlocal@dev-jboss02.com:/home/devlocal"     password="password" trust="true"    verbose="true"  port="22"/>
               </target>
           </configuration>
       </execution>

6. Also on the sshd log, I see it says client is using JSCH-0.1.38, where client is using jsch-0.1.44, I dont have JSCH-0.1.38 neither in ant lib's or in mvn repo anywhere..

7. I am keen to get the password authentication and not key authentication, as this is a automation project where the VM image create for each run.

Have you installed the JSch library where your ant installation can see it? Ant scp task documentation clearly states that this is necessary:

Note: This task depends on external libraries not included in the Ant distribution. See Library Dependencies for more information.

There, you'll find that

jsch.jar 0.1.50 or later

is required for the SCP task.

JSCh is available here:

Try using Maven 3, Maven 2 embeds jsch 0.1.38 and it takes the precedence over the version specified in the plugin dependencies. This was resolved in Maven 3.
