A zip_file() allows builds to create basic zip files in a platform-agnostic way.

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

• entries_to_exclude: List of regex expressions that describe entries that should not be included in the output zip file.

  The regexes must be defined using java.util.regex.Pattern syntax.

• hardcode_permissions_for_deterministic_output: If set to true, Buck hardcodes the permissions in order to ensures that all files have the same permissions regardless of the platform on which the zip was generated.

• on_duplicate_entry: Action performed when Buck detects that zip_file input contains multiple entries with the same name.

  The valid values are:

  • overwrite (default): the last entry overwrites all previous entries with the same name.
  • append: all entries are added to the output file.
  • fail: fail the build when duplicate entries are present.

• out: The name of the zip file that should be generated. This allows builds to use a meaningful target name coupled with a meaningful zip file name. The default value takes the rule's name and appends .zip.

• srcs: The set of files to include in the zip.

  Each src will be added to the zip as follows:

  • If the src is the output of another rule, the output will be included using just the output's file name.
  • If the src is a file relative to the rule's declaration, it will be included in the zip with its relative file name.

• zip_srcs: The set of zip files whose content to include in the output zip file.

  Note that the order of files in zip_srcs matters because the same zip entry can be included from multiple files. See the on_duplicate_entry argument to learn how to control the behavior when there are multiple entries with the same name.

  The entries from zip_srcs are added before files from srcs.

Details

Examples:

This example will create a simple zip file.

zip_file(
  # The output will be "example.zip"
  name = 'example',
  srcs =
    # These files will be found in the zip under "dir/"
    glob(['dir/**/*']) +
    [
      # Imagine this generates the output
      # "buck-out/gen/foo/hello.txt". This output will
      # be found in the zip at "hello.txt"
      '//some/other:target',

    ],
  zip_srcs = [
     # The contents of this zip will be added to the generated zip.
    'amazing-library-1.0-sources.zip',
  ],
  entries_to_exclude = [
    "com/example/amazinglibrary/Source1.java",
  ],
)

If you were to examine the generated zip, the contents would look something like (assuming the output of "//some/other:target" was a file who's path ended with hello.txt, the "dir" glob found two files, and "amazing-library-1.0-sources.zip" contained two Java source files):

dir/file1.txt
dir/subdir/file2.txt
hello.txt
com/example/amazinglibrary/Source2.java
