Question

I have one requirement: copy local files to remote system.
I have done the following:

1. downloaded jsch-0.1.44.jar and copied to lib folder of Ant
2. set the path and every thing

My buildfile is:

<project name="ImportedBuild" default="all">
  <target name="copyFileToRemote">
    <echo>2222222222 copyFileToRemote Examples:::::::::::::</echo>
    <scp file="sample.txt" todir="${username}:${password}@${hostname}:/shared"/>
  </target>
</project>

When I run Ant, I get this error:

BUILD FAILED com.jcraft.jsch.JSchException: reject HostKey: 10.184.74.168
    at com.jcraft.jsch.Session.checkHost(Session.java:712)
    at com.jcraft.jsch.Session.connect(Session.java:313)
    at com.jcraft.jsch.Session.connect(Session.java:154)

    at org.apache.tools.ant.taskdefs.optional.ssh.Scp.execute(Scp.java:203)
    at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:288)
    ... etc ...

Any ideas how to resolve this?

Answer 1

According to the Ant scp task docs, trust attribute:

This trusts all unknown hosts if set
to yes/true. Note If you set this to
false (the default), the host you
connect to must be listed in your
knownhosts file, this also implies
that the file exists.

The trust attribute is not used in your task call, so it appears that the host (10.184.74.168) is not in your knownhosts file. Suggest you add trust="true", or add the host to the knownhosts file.
