Answer 1

To view all builds run the following in your terminal:

heroku builds -a YOUR_APP_NAME

To cancel a specific (pending) build:

heroku builds:cancel -a YOUR_APP_NAME HEROKU_BUILD_ID

If you see the message Warning: builds is not a heroku command, run heroku plugins:install heroku-builds and try again.

Answer 2

If you have a build going into production right now and need to stop it quickly:

heroku plugins:install heroku-builds
heroku builds:cancel -a YOUR_HEROKU_APP_NAME

Answer 3

The heroku-builds CLI plugin has a builds:cancel command which will stop a running build.

All builds will time out too after a time that can go between 15 minutes to 1 hour.
