This rule provides access to a set of files.

Parameters​

  • name: name of the target
  • default_target_platform: specifies the default target platform, used when no platforms are specified on the command line
  • target_compatible_with: a list of constraints that are required to be satisfied for this target to be compatible with a configuration
  • compatible_with: a list of constraints that are required to be satisfied for this target to be compatible with a configuration
  • exec_compatible_with: a list of constraints that are required to be satisfied for this target to be compatible with an execution platform
  • visibility: a list of visibility patterns restricting what targets can depend on this one
  • within_view: a list of visibility patterns restricting what this target can depend on
  • metadata: a key-value map of metadata associated with this target
  • tests: a list of targets that provide tests for this one
  • modifiers: an array of modifiers associated with this target
  • executable_bit_override: Override the executable bit for every file in the filegroup. If not set, the executable bits are preserved. Cannot be used if copy is set to false.
  • out: The name of the output directory. Defaults to the rule's name.
  • srcs: The set of files to include in this rule.

Details​

Files are accessible to genrule()s by using their relative path after a $(location) string parameter macro.

Other rules may handle filegroup() rules natively for attributes such as resources.

Examples:

In this example a target exports .xml files from all subdirectories in resources.


filegroup(
  name = 'example',
  srcs = glob(['resources/**/*.xml']),
)

genrule(
  name = 'process_xml',
  out = 'processed.xml',
  cmd = '$(exe //example:tool) -in $(location :example)/resources/file.xml > $OUT',
)
