Provide your expert option for the problem that I encountered at work.
Ant SCP task does not work - where can I scp use cygwin.
Local environment: Windows 7 64 bit, Jdk 1.6.0.24, Ant -1.8.2 (with ant additional dependencies added), maven 2 (usign ant run plugin), jsch-0.1 0.44 Remote environment: VM Labmanager 4.0, Windows Server 2008 - R2, SSH-2.0-OpenSSH_5.8, JDK 1.6.0.24
I set password authentication to yes and restarted sshd on the remote host.
The purpose of Maven is as follows. (btw, I accomplished the same ant goal, so ant and Maven give 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> <id>copy-installer</id> <phase>process-resources</phase> <goals> <goal>run</goal> </goals> <configuration> <target> <scp file="readme.txt" todir=" devlocal@dev-jboss02.com :/home/devlocal" password="password" trust="true" verbose="true" port="22"/> </target> </configuration> </execution> </executions> <dependencies> <dependency> <groupId>com.jcraft</groupId> <artifactId>jsch</artifactId> <version>0.1.42</version> </dependency> <dependency> <groupId>org.apache.ant</groupId> <artifactId>ant-jsch</artifactId> <version>1.8.2</version> </dependency> </dependencies>
The stack trace is as follows:

Also in the sshd log, I see that the client uses JSCH-0.1.38, where the client uses jsch-0.1.44, I have no AKH-0.1.38 in either ant lib, or in mvn repo anywhere ..

I am interested in password authentication, but not in key authentication, as this is an automation project in which a virtual machine image is created for each launch.
