#13 Cannot use task scp though Ant finds jsch.jar

[Anonymous]

I am trying to use scp through Apache Ant, but Ant is failing to use the appropriate classes. Here is the error message I have got from Ant:

INFO - BUILD FAILED
INFO - /home/.../deploy2.xml:55: Could not create task or type of type: scp.
INFO -
INFO - Ant could not find the task or a class this task relies upon.

If I run diagnostics, I receive this information:

As you can see, I have tried to include several versions of jsch.jar in every combination I can image (the one featured is all the .jars I have downloaded thus far).
