executing RSYNC command in jenkins

Host key verification failed.

The account running jenkins likely has a bad value for the host key for the machine you are sshing to in ~/.ssh/known_hosts.

Well I replaced the know_host files but I was still having issues. so for anyone that has issues with the know_host file you would fix the offending key by doing a:

ssh-keygen -R hostnameOfOfendingKey

and this will remove the ofending key and now your known_host file is working again.

NOW to resolve the other issue I found the answer in this other place: https://stackoverflow.com/questions/25755418/executing-rsync-in-jenkins/25770519#25770519

and This was what I did to solve it

sudo su jenkins -s /bin/bash

then once as jenkins user copy my ssh key to the server I want to connect/execute commands in, etc

ssh-copy-id [email protected]

it then will present you this

[email protected]'s password: 
Now try logging into the machine, with "ssh '[email protected]'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

then I did this for testing purposes:

bash-4.1$ rsync -PSauve ssh --exclude=JenkinsBuild /srv/pd/* [email protected]:/srv/pdc/test1  

and it passed without asking for password or anything. Notice that I'm still log as jenkins.

So now when I created the Jenkins job with some shell commands as part of the build it will work as expected :D
