Hey Everyone,
I am new to plugin creation, and have a need to create a plugin that
generates a specific file based on user-input to a remote node
containing large strings of data.
*I am aware of the current "Execute Shell" build step option and
"Execute remote commands via SSH" plugin,
but do not want users to have to input this large string of data
themselves into the job config shell execute text field.*
https://wiki.jenkins-ci.org/display/JENKINS/Managed+Script+Plugin
https://wiki.jenkins-ci.org/display/JENKINS/SharedObjects+Plugin
For now, I would like to create a plugin that can execute shell
commands on a remote node, once I have this, I should be able to
figure out the rest myself.
I found this code snippet (below) which works fine for executing
simple shell commands on local jenkins system.
What I want to do is modify this code snippet to also work when the
job is configured to execute on a remote node.
When I configured the job to execute on a remote node, I received the
following error (below below)
If executing the commands on the remote node is too hard, is there a
way to auto-input that large string of data into the execute shell
text box in the jenkins job configuration, as this would work too?
Can anyone assist?
Thanks very much in advance,
~Ravid
