I am currently trying to build a Declarative Pipeline with a conditional stage.
The condition should be triggered by the result of a shell command on my project (following the pipeline-as-glue pattern: my developer needs to know this on another environments as Jenkins, so using a script).
This shell command respond the string "false" or "true".
Based on this feedback, then I run the stage or not.
After some digging, it appears calling a "sh" step within an expression is no longer working: it throws the following exception "
I tried the pipeline on https://jenkins.io/blog/2017/01/19/converting-conditional-to-pipeline/#longer-pipeline and I got the same error.
Here is the full exception: https://gist.github.com/dduportal/7ae612501b848a55ad29fe421d775b96
I am currently trying with a shared library to see if the same issue occurs, I'll let you know.
Don't hesitate to ask if you miss information from me.
Thanks in advance for your time!
