List of labels; optional

The list of files needed by this rule at runtime.

Targets named in the data attribute will appear in the *.runfiles area of this rule, if it has one. This may include data files needed by a binary or library, or other programs needed by it. See the data dependencies section for more information about how to depend on and use data files.

Almost all rules permit a data attribute, but where this attribute is not allowed, this fact is documented under the specific rule.
