check_buildpack_version

Print out a warning message when the current buildpack used for staging is a different version than the version of the buildpack used for the last successful staging.

• The buildpacks need to be the same buildpack (i.e. have the same language value in their manifest.yml files.) for the version check to apply.

store_buildpack_metadata

Write the version of the current buildpack used for staging and the language (language value in its manifest.yml file) to a metadata file (BUILDPACK_METADATA) in the buildpack app cache directory.

./compile-extensions/bin/store_buildpack_metadata [STAGING_BUILDPACK_DIR] [CACHE_DIR]
