Each Vagrant command supports a --machine-readable flag, which is very useful for the purposes of this project. However, when attempting to run vagrant destroy --machine-readable, the following error is encountered:

$ vagrant destroy --machine-readable
1554063395,default,metadata,provider,virtualbox
1554063395,default,action,destroy,start
1554063395,,ui,error,Vagrant is attempting to interface with the UI in a way that requires\na TTY. Most actions in Vagrant that require a TTY have configuration\nswitches to disable this requirement. Please do that or run Vagrant\nwith TTY.
1554063395,,error-exit,Vagrant::Errors::UIExpectsTTY,Vagrant is attempting to interface with the UI in a way that requires\na TTY. Most actions in Vagrant that require a TTY have configuration\nswitches to disable this requirement. Please do that or run Vagrant\nwith TTY.

This happens because Vagrant would normally ask for confirmation before destroying the box, but cannot do so via the machine-readable interface, so rather than continuing it fails with an error. As you can see, this happens even when running the command from a terminal, so it's rather confusing. However, the error does not occur when the --force flag is added, so the destroy task in this project must use that flag whenever it runs.
