public class ExportFile extends AbstractBuildRule implements HasOutputName, HasRuntimeDeps, SupportsInputBasedRuleKey
BuildRule
s. There are several
valid ways of using export_file (all examples in a build file located at "path/to/buck/BUCK").
The most common usage of export_file is:
export_file(name = 'some-file.html')This is equivalent to:
export_file(name = 'some-file.html', src = 'some-file.html', out = 'some-file.html')This results in "//path/to/buck:some-file.html" as the rule, and will export the file "some-file.html" as "some-file.html".
export_file( name = 'foobar.html', src = 'some-file.html', )Is equivalent to:
export_file(name = 'foobar.html', src = 'some-file.html', out = 'foobar.html')Finally, it's possible to refer to the exported file with a logical name, while controlling the actual file name. For example:
export_file(name = 'ie-exports', src = 'some-file.js', out = 'some-file-ie.js', )As a rule of thumb, if the "out" parameter is missing, the "name" parameter is used as the name of the file to be saved.

argument for this build rule in the build file in which it was defined.
However, there are special cases where other arguments pull in implicit dependencies
(e.g., the keystore
argument in android_binary
). In these cases, the
implicit dependencies are also included in the set returned by this method. The value of
the original deps
argument, as defined in the build file, must be accessed via a
custom getter provided by the build rule.

can be cached.
Uncached build rules are never written out to cache, never read from cache, and does not count in cache statistics. This rule is useful for artifacts which cannot be easily normalized.
Uncached rules are not always rebuilt, however, as long as the existing on-disk
representation is up to date. This means that these rules can take advantage of SupportsInputBasedRuleKey
to prevent rebuilding.
