Apache Ants sshexec task and a passphrase problem under Mac OS X

Question

I would like to use a sshexec task in Apache Ant under Mac OS X like this:

<!-- ... -->
<target name="uname">
    <sshexec host="${host}" keyfile="${user.home}/.ssh/id_rsa" username="${user}" command="uname -ar" />
</target>
<!-- ... -->

But i will only get an error "Auth cancel" for "ant uname":

After playing around i just found out that i have to add my passphrase as a parameter "passphrase" to the task:

<!-- ... -->
<target name="uname">
    <sshexec host="${host}" keyfile="${user.home}/.ssh/id_rsa" passphrase="my.secret.passpgrase" username="${user}" command="uname -ar" />
</target>
<!-- ... -->

But i have perfectly setup Mac OS X with a working integration for the passphrases management to my keychain. So i don't have to enter the passphrase every time.

Is there a way that the sshexec and also the scp task can use the phrases stored in my keychain?
