I compiled and applied this on a Jenkins machine to do AWS EC2 spin-up. I had run into the same issue with the job aborting because "y" was not pressed.

Confirmed to work with Terraform v0.11.7, Jenkins ver. 2.89.3.

I haven't had a chance to verify if this is backwards compatible with older terraform versions? If not I think a checkbox/option should be available

It appears --auto-approve will break on anything older than 0.10.0 "flag provided but not defined: -auto-approve".

Also, with the addition of -auto-approve, -force was deprecated on terraform destroy and replaced with -auto-approve
