--repo-sync {always,cached-okay,never}

Mode for repository metadata synchronization. Default is always.

always

Always try to keep the repository metadata up-to-date. If there is a failure to validate/update the repo metadata, the build fails immediately.

cached-okay

Attempt to update the repository metadata. If a low-level network error prevents such an update and we have cached metadata for the repository, ignore the error and continue.

never

Do not try to update the repository metadata. This option requires that there be a local cache of the repository metadata before being used.

If any packages need to be pulled for the build and those packages are not already locally cached, bpt will still attempt to download those packages from the repository.

Regardless of this option, the HTTP Cache-Control headers for the repository data will be respected. If repository data is within the lifetime of the max-age of the resource, bpt will not try to update the repository data.
