Multiple invocations

[Dominique Devienne <dd...@gmail.com>]

First time <sshexec> user, so please be gentle ;-)
I'm using Ant 1.6.2 with Jsch 0.1.21.

I'm a bit baffled by the results I get using <sshexec>.
The session below shows all relevant information.

If I run just one target, doing one <sshexec>,
it works fine, i.e. I get the echo to execute correctly.

If I run twice the same target (build linux linux),
the first <sshexec> works, but the second fails with
an "Auth cancel" exception.

If OTOH the two <sshexec> belong to the same project,
i.e. are executed as dependencies of a single target
(build linux-solaris), then the first one works, but
the second one this time doesn't fail, but doesn't
provide any output at all.

All invocations are below, and show what I mean.

Anybody has any insight? Thanks, --DD

no - it has been like this for a while (at least a couple of years). 
*Please* someone tell me I am wrong. (and how to do it right...)

I have gone to opening FTP access for select IP addresses under my control.

Note that I tried Ant 1.6.5 and 1.7 (CVS HEAD), with the same Jsch and
they all behave the same way. Maybe I need to try an older version of
Jsch... --DD
