By default, the build tool won't attempt to rebuild a binary archive that is
already present in the depot. However, it is possible to force a rebuild via
the 'FORCE=1' argument.

Publishing archives
@ -474,6 +474,15 @@ updates hash files of the involved recipes by taking the current date as
version name. This is a valuable assistance in situations where a commonly
used API changes. In this case, the versions of the API and all dependent
archives must be increased, which would be a labour-intensive task otherwise.
If the depot already contains an archive of the current version, the create
tools won't re-create the depot archive by default. Local modifications of
the source code in the repository do not automatically result in a new archive.
To ensure that the depot archive is current, one can specify 'FORCE=1' to
the create tool. With this argument, existing depot archives are replaced by
freshly extracted ones and version updates are detected. When specified for
creating binary archives, 'FORCE=1' normally implies 'REBUILD=1'. To prevent
the superfluous rebuild of binary archives whose source versions remain
unchanged, 'FORCE=1' can be combined with the argument 'REBUILD='.
