A single resource file embedded in a code package and accessed in a location-independent manner.
Resources are embedded in code artifacts such as Python wheels or JVM JARs. The sources of a
resources target are accessed via language-specific resource APIs, such as Python's
pkgutil or JVM's ClassLoader, via paths relative to the target's source root.
str | http_source | pants.core.target_types.per_platform[pants.core.target_types.http_source]
The source of this target.
If a string is provided, represents a path that is relative to the BUILD file's directory, e.g.
http_source is provided, represents the network location to download the source from. The downloaded file will exist in the sandbox in the same directory as the target.
http_source has the following signature:
http_source(url: str, *, len: int, sha256: str, filename: str = "")
The filename defaults to the last part of the URL path (e.g.
example.ext), but can also be specified if you wish to have control over the file name. You cannot, however, specify a path separator to download the file into a subdirectory (you must declare a target in desired subdirectory).
You can easily get the len and checksum with the following command:
curl -L $URL | tee >(wc -c) >(shasum -a 256) >/dev/null
per_platform is provided, represents a mapping from platform to
http_source, where the platform is one of (
macos_x86_64) and is resolved in the execution target. Each
http_source value MUST have the same filename provided.
Iterable[str] | None
Addresses to other targets that this target depends on, e.g.
['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].
This augments any dependencies inferred by Pants, such as by analyzing your imports. Use
pants dependencies or
pants peek on this target to get the final result.
See Targets and BUILD files for more about how addresses are formed, including for generated targets. You can also run
pants list :: to find all addresses in your project, or
pants list dir to find all addresses defined in that directory.
If the target is in the same BUILD file, you can leave off the BUILD file path, e.g.
:tgt instead of
helloworld/subdir:tgt. For generated first-party addresses, use
./ for the file path, e.g.
./main.py:tgt; for all other generated targets, use
You may exclude dependencies by prefixing with
['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.
str | None
A human-readable description of the target.
pants list --documented :: to see all targets with descriptions.
Iterable[str] | None
Arbitrary strings to describe a target.
For example, you may tag some test targets with 'integration_test' so that you could run
pants --tag='integration_test' test :: to only run on targets with that tag.
