Cache not found - single step Pipeline build

[sid6mathur]

Hi folks, 

My pipeline build is unable to persist the $HOME/.cache directory across builds, hence running very slowly. Can someone find any errors in the caching setup below? 

Log message in the "Build setup" phase: 

Cache "mytool-cache-dir: $HOME/.cache": Downloading

Cache "mytool-cache-dir: $HOME/.cache": Not found

My Pipeline YAML simply downloads a CLI tool off the web, and runs it for a while. The network downloads fetched by the tool live in $CWD/.cache of the tool run, and should be persisted across repeat runs of the build.

I realized after posting this that the $PWD is not $HOME, which is my assumption in the above script. So I remove $HOME relative paths and let them be either relative to $(pwd) (present working directory) or better still the $BITBUCKET_CLONE_DIR variable. 

So now both the cache works and the artefacts are found correctly after the build is done. Yay!
