remote_file

A remote_file() rule is used to download files from the Internet to be used as dependencies for other rules. These rules are downloaded by running fetch, or can be downloaded as part of build. See the note there about the .buckconfig setting to configure that.

Parameters

name: (required)

name of the target
default_target_platform: (defaults to: None)

specifies the default target platform, used when no platforms are specified on the command line
target_compatible_with: (defaults to: [])

a list of constraints that are required to be satisfied for this target to be compatible with a configuration
compatible_with: (defaults to: [])

a list of constraints that are required to be satisfied for this target to be compatible with a configuration
exec_compatible_with: (defaults to: [])

a list of constraints that are required to be satisfied for this target to be compatible with an execution platform
visibility: (defaults to: [])

a list of visibility patterns restricting what targets can depend on this one
within_view: (defaults to: ["PUBLIC"])

a list of visibility patterns restricting what this target can depend on
metadata: (defaults to: {})

a key-value map of metadata associated with this target
tests: (defaults to: [])

a list of targets that provide tests for this one
modifiers: (defaults to: [])

an array of modifiers associated with this target
contacts: (defaults to: [])

A list of organizational contacts for this rule. These could be individuals who you would contact in the event of a failure or other issue with the rule.
```
contacts = [ 'Joe Sixpack', 'Erika Mustermann' ]
```
labels: (defaults to: [])

Set of arbitrary strings which allow you to annotate a build rule with tags that can be searched for over an entire dependency tree using buck query().
licenses: (defaults to: [])

Set of license files for this library. To get the list of license files for a given build rule and all of its dependencies, you can use buck query
out: (defaults to: None)

An optional name to call the downloaded artifact. Buck will generate a default name if one is not provided that uses the name of the rule.
size_bytes: (defaults to: None)

Size in bytes of the downloaded artifact. Buck verifies this is correct and fails the fetch command if it doesn't match (only when a SHA-1 hash is used).
type: (defaults to: None)

An optional type of the downloaded file.

data Regular data file. executable

Executable file. Buck will ensure that output has appropriate permissions if applicable.

exploded_zip

Zip archive which will be automatically unzipped into an output directory.
url: (required)

You can specify an http, https, or a mvn URL. If you specify a mvn URL, it will be decoded as described in the javadocs for MavenUrlDecoder See the example section below.
vpnless_url: (defaults to: None)

An optional additional URL from which this resource can be downloaded when off VPN. Meta-internal only.

Examples

Here's an example of a remote_file() using an https URL.

remote_file(
  name = 'android-ndk-r10e-darwin-x86_64',
  url = 'https://dl.google.com/android/ndk/android-ndk-r10e-darwin-x86_64.bin',
  sha1 = 'b57c2b9213251180dcab794352bfc9a241bf2557',
)

Here's an example of a remote_file() using a mvn URL being referenced by a prebuilt_jar().

prebuilt_jar(
  name = 'jetty-all',
  binary_jar = 'jetty-all-9.2.10.v20150310.jar',
  source_jar = ':jetty-source',
)

remote_file(
  name = 'jetty-source',
  out = 'jetty-all-9.2.10.v20150310-sources.jar',
  url = 'mvn:org.eclipse.jetty.aggregate:jetty-all:src:9.2.10.v20150310',
  sha1 = '311da310416d2feb3de227081d7c3f48742d7075',
)

Here's an example of a remote_file() using a mvn URI which uses a non-default maven repository host.

remote_file(
  name = 'jetty-source',
  out = 'jetty-all-9.2.10.v20150310-sources.jar',
  url = 'mvn:https://maven-repo.com:org.eclipse.jetty.aggregate:jetty-all:src:9.2.10.v20150310',
  sha1 = '311da310416d2feb3de227081d7c3f48742d7075',
)

Here's an example of a remote_file() using a mvn URI which uses a Maven classifier.

remote_file(
  name = 'groovy-groovysh-indy',
  out = 'jetty-all-9.2.10.v20150310-sources.jar',
  url = 'mvn:org.codehaus.groovy:groovy-groovysh:jar:indy:2.4.1',
  sha1 = '1600fde728c885cc9506cb102deb1b494bd7c130',
)
