Deprecation notice: 7

The ‘prepare’ keyword has been replaced by 'override-build’

introduced in snapcraft 2.41

The prepare scriptlet was originally introduced as a way to “prepare” for a build. However, as part of an effort to add support for Snapcraft to have this for all lifecycle steps (i.e. not just build), a new scriptlet has been added that encompasses this functionality called override-build.

It’s also possible to replace prepare with override-pull, depending on your requirements.

override-build allows you to override the default build step with your own logic, from which you can call snapcraftctl build to run the default build step.

Let’s say you currently had a prepare scriptlet that looked like this:

prepare: |
  echo "This runs before build!"

To get equivalent functionality with the override-build scriptlet, try this:

override-build: |
  echo "This runs before build!"
  snapcraftctl build
