`--write-locks`::
Indicates that all resolved configurations that are _lockable_ should have their <<dependency_locking.adoc#dependency-locking,lock state>> persisted.

`--update-locks <group:name>[,<group:name>]*`::
Indicates that versions for the specified modules have to be updated in the <<dependency_locking.adoc#dependency-locking,lock file>>.
