-Description
-
-If build failure caching is enabled through the
-build-cache-failure configuration option, the
-operation clears the “failed”
-state of the given store paths, allowing them to be built again. This
-is useful if the failure was actually transient (e.g. because the disk
-was full).
-
-If a path denotes a derivation, its output paths are cleared.
-You can provide the argument * to clear all store
-paths.
