How properly to create custom dependency cache with file checksum-based hashing?

etreskovskis

I am trying to use the caches key option to create a custom dependency cache with file checksum-based hashing according these examples:

https://support.atlassian.com/bitbucket-cloud/docs/cache-and-service-container-definitions/#Caches

https://bitbucket.org/blog/announcing-smarter-caches-bitbucket-pipelines

 

definitions:
caches:
pip: ~/.cache/pip
virtualenv: venv
proxies: $BITBUCKET_CLONE_DIR/artifacts/proxies
googleapi:
path: services/google_api/dependencies
key:
files: [ $BITBUCKET_CLONE_DIR/services/google_api/dependencies/dependency.json ]

however the step always fails with error: 

Cache "googleapi: services/google_api/dependencies": Cache key files could not be found.
HOW to solve this issue? Tried different options to provide different format paths for the `path` variable

It works ONLY in this way:

 

definitions:
caches:
pip: ~/.cache/pip
virtualenv: venv
proxies: $BITBUCKET_CLONE_DIR/artifacts/proxies
googleapi: $BITBUCKET_CLONE_DIR/services/google_api/dependencies

Hi @etreskovskis  and welcome to the community!

I believe the issue is that you're using an absolute path for the key file. Cache directory paths can be absolute, or relative to the clone directory, but the path to the key files needs to be relative to the clone directory.

Could you try the following definition?

definitions:
  caches:
    pip: ~/.cache/pip
    virtualenv: venv
    proxies: $BITBUCKET_CLONE_DIR/artifacts/proxies
    googleapi:
      path: services/google_api/dependencies
      key:
        files: [ services/google_api/dependencies/dependency.json ]

Kind regards,
Theodora
