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.*
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
