/**
 * Repackages all of the current archives in target/ with the same build
 * number, sha, and commit hash. This is useful when all you need to do is bump
 * the version of the release and do not want to introduce any other changes.
 *
 * Even if there are new commits, the standard build task reinstalls all npm
 * dependencies, which introduces at least a small amount of risk of
 * introducing bugs into the build since not all dependencies have fixed
 * versions.
 *
 * Options:
 *   --skip-archives        Will skip the archive step, useful for debugging
 *   --buildversion="1.2.3" Sets new version to 1.2.3
 *   --buildnum="99999"     Sets new build number to 99999
 *   --buildsha="9a5b2c1"   Sets new build sha to 9a5b2c1 (use the full sha, though)
