Executing SSH commands from ANT

ou can easily achieve remote command invocation, using an ANT Task sshexec. An example of its usage could be this snippet (note that remote.* variables are taken from the *.properties file in this case):

<sshexec host="${}"
         command="rm -rf ${remote.webapps.path}/ROOT*" />

You can read about more detailed examples here.

To add this feature to your ANT installation, you need to download the JSch – Java Secure Channel library and include the jsch jar file into ANT classpath (i.e. in your ANT_HOME/lib/ or — if you’re using an Eclipse — into Eclipse Ant classpath).

I found this feature quite useful as it reduced time I needed to build and deploy an application.
