How to backport SShSession to Ant 1.7.1

I am stuck with Ant 1.7.1 for the moment for reasons I wont get into. I'd like to be able to use the SshSession Ant task to create SSH tunnels to some of my servers. But SshSession was introduced only in A开发者_如何转开发nt 1.8.0.

I have no experience with custom Ant tasks. Would it be difficult to backport this task from 1.8.0 to 1.7.1 ? Where should I go to learn more on how to do that ?

Thanks for your help !

It looks like the source for the SShSession task is compatible with ant 1.7. Get the source for this task, and compile against ant 1.7 and the jsch jar. Then create a taskdef pointing to the class you've just created (jsch.jar will need to be in the ant lib dir or specified using the -lib option) and you should be good to go.
