I’m trying to use the sshexec task for ANT on my OSX box, when I try to run it I get the error listed below. I’ve downloaded the jsch jar file from: http://www.jcraft.com/jsch/index.html version jsch-0.1.43.jar

I placed that file into /usr/share/ant/lib and still the error occurs. any ideas?

thanks

<target name="testme" depends="">
 <sshexec host="myhost1" username="${username}" command="ls -la" keyfile="${user.home}/.ssh/id_rsa" />
</target>

I get the following error:

BUILD FAILED
/Users/jim/Code/myapp/deploy.xml:16: Problem: failed to create task or type sshexec
Cause: the class org.apache.tools.ant.taskdefs.optional.ssh.SSHExec was not found.
        This looks like one of Ant's optional components.
Action: Check that the appropriate optional JAR exists in
        -/usr/share/ant/lib
        -/Users/jim/.ant/lib
        -a directory added on the command line with the -lib argument

Do not panic, this is a common problem.
The commonest cause is a missing JAR.

UPDATE::::
I installed a new version of ANT from apache and put it in /usr/local and moved the jsch file into /usr/local/ant/lib and it fixes the error, however now I have a new one when I run it with: ant -f deploy.xml restart
