Re: Ant sshexec random failures
Hi Chris...
I am having the same exactly problem with the sshexec, the same script
sometimes works, sometimes it gives me "Remote command failed with exit
status -1" , I was wondering if you have found the reason for this and a
possible solution ?
this is driving me crazy since I can't find the exactly (valid) reason , so
i can talk with my manager about it..
thanks in advance

Replying for cprice - the patch below definitely seems to have made the
problem much less noticable. Previous to applying this patch, we had a
shell script that ssh'ed to a remote box continuously overnight and failed
around 7 - 8 times. Now it doesn't fail at all.
Thanks!

Hi,
Has anyone posted a bug on BZ for this?
If we have an open bug report and a patch & test for it, we can
perform the fix and get it into the trunk of ant for 1.7.1
Thanks,
Kev

Regarding my earlier post, the upgrade from JSch 0.1.31 to 0.1.33 did not
make any difference. It sounds like that Ant patch will help though.

I am facing this problem also. Has a bug been opened up for this? I'm
unable to find it in bugzilla....

May I ask you to try the attached patch? It is a patch for SVN HEAD.
Re: Ant sshexec random failures
Posted by Andrew Goktepe <an...@gmail.com>.
Same problem for me too. We have been experiencing this intermittently for
the past few months. It started happening for me again yesterday, and I am
sure that the remote script is exiting with 0 status. This seems like a JSch
bug to me. I have been running JSch 0.1.31 but I just upgraded to the new
v0.1.33. I'll update this thread with the results.
