Ant scp task not working, even with jsch on ant/lib
ant, build, java, scp, task
Solution
This looks like your problem, from the top of the diagnostics:
optional tasks : not available
Your $ANT_HOME/lib directory is missing ant-jsch.jar, which is where your missing class comes from.
I'm not sure how this happened - I always install Ant from the ZIP file on the download site, which includes all the optional tasks. If you installed Ant from a Linux package, try checking to see if there is a separate package for the optional tasks.
Once you get the optional tasks installed, I would delete the old version of jsch.jar as @trashgod suggests.
Problem
I need to copy a war file via scp. I have added the `jsch-0.1.42.jar` to `$ANT_HOME/lib` but I'm still getting this error: Cause: the class org.apache.tools.ant.taskdefs.optional.ssh.Scp was not found. This looks like one of Ant's optional components. This is the result of running `ant -diagnostics` just in case: http://gist.github.com/320859
