Scoping of a groovy variable inside a closure in try() to access from catch()

how do i access the value of a variable assigned inside a closure within a try() in the catch() statement. here is what i am trying to achieve but i keep getting the initialization value that i assigned. node('linux') { def val_log = null; try{ stage('abc') { val_log = //some steps that generates a log that i want } println '$val_log' //this works } catch(err) stage('mail') { // code to send email notification with '$val_log' //--> the $val_log returns 'null' and not the //value assigned in the try() part. } } Is there a way, to get the value for the variable inside the catch() statement. Thank you...

You don't need to initialize to null outside the try, just "def val_log" is fine. I've used this in my pipeline and it works fine. Can you verify that your pipeline is getting to the point where val_log is assigned, and also verify it's not assigned anywhere else?

thanks, that seems to make sense with what i am noticing. Seems like the root cause is that, the variable is not assigned if the 'shell' step fails / non 0 exit status. 

i am trying to assign the variable with the shell scripts stdout. I would like to capture the stacktract so that it prints the shell scripts stdout/stderr in the mail, rather than the generic "'hudson.AbortException: script returned exit code 1'"
