we want to use snapcraft in the CI. we have makefile and there has CC_VER=0.1.2, how can i use the CC_VER and set the version to CC_VER in snapcraft.yaml.
You can use the
environment: keyword. See this topic:
Reading the original post this looks more like an env var you would set at build time …
environment: keyword only works inside the
apps: area or at the toplevel of snapcraft.yaml but not for specific
parts: entries, there you might have to use
override-build:| with an export statement and call
snapcraftctl build after it.
Unfortunately that doesn’t work.
snapcraftctl will create a new environment so any exports you do in the override script get lost. The only way to do this is to recreate the entire build step in procedural code in

This is documented on https://docs.snapcraft.io/reference/plugins/make or by running
snapcraft help make. We could add an example like this to make it more clear though.
