# Clearing the Cache

As an artifact server Seal only has visibility to those artifacts that are pulled by the build machine. Therefore, if instead of pulling libraries from an artifact server the build machine uses a locally cached copy, the Seal server will be unaware of its usage.

To get an up-to-date snapshot of the packages used as part of your build process, you should first clear your package manager's cache.
