try/catch in a pipeline?

[Peter Berghold]

I've noticed some "non-deterministic behavior" in my first few pipelines and I was wondering if there i some sort of try/catch structure I could use to catch errors.  It would sort of look like this: 

try { 

      sh 'some_unix_command'

} catch { 

     send_mail('Step foo failed on some_unix_command') 

}

On this page https://jenkins.io/doc/book/pipeline/jenkinsfile/#syntax there is a Handling Failures section which might help you.

you can use post section in pipeline post or you can write try catch in script step.
