Known versions to verify downloads against.
Each element is a pipe-separated string of version|platform|sha256|length
or
version|platform|sha256|length|url_override
, where:
version
is the version stringplatform
is one of[linux_arm64,linux_x86_64,macos_arm64,macos_x86_64]
sha256
is the 64-character hex representation of the expected sha256 digest of the download file, as emitted byshasum -a 256
length
is the expected length of the download file in bytes, as emitted bywc -c
- (Optional)
url_override
is a specific url to use instead of the normally generated url for this version
E.g., 3.1.2|macos_x86_64|6d0f18cd84b918c7b3edd0203e75569e0c7caecb1367bbbe409b44e28514f5be|42813
.
and 3.1.2|macos_arm64 |aca5c1da0192e2fd46b7b55ab290a92c5f07309e7b0ebf4e45ba95731ae98291|50926|https://example.mac.org/bin/v3.1.2/mac-aarch64-v3.1.2.tgz
.
Values are space-stripped, so pipes can be indented for readability if necessary.
tailor
--[no-]protoc-tailor
PANTS_PROTOC_TAILOR
[protoc]
tailor = <bool>
True
If true, add protobuf_sources
targets with the tailor
goal.
url_platform_mapping

PANTS_PROTOC_URL_PLATFORM_MAPPING

A dictionary mapping platforms to strings to be used when generating the URL to download the tool.
In --url-template
, anytime the {platform}
string is used, Pants will determine the current platform, and substitute {platform}
with the respective value from your dictionary.
For example, if you define {"macos_x86_64": "apple-darwin", "linux_x86_64": "unknown-linux"}
, and run Pants on Linux with an intel architecture, then {platform}
will be substituted in the --url-template
option with unknown-linux
.
url_template
--protoc-url-template=<str>
PANTS_PROTOC_URL_TEMPLATE
[protoc]
url_template = <str>
https://github.com/protocolbuffers/protobuf/releases/download/v{version}/protoc-{version}-{platform}.zip
URL to download the tool, either as a single binary file or a compressed file (e.g. zip file). You can change this to point to your own hosted file, e.g. to work with proxies or for access via the filesystem through a file:$abspath
URL (e.g. file:/this/is/absolute
, possibly by templating the buildroot in a config file).
Use {version}
to have the value from --version
substituted, and {platform}
to have a value from --url-platform-mapping
substituted in, depending on the current platform. For example, https://github.com/.../protoc-{version}-{platform}.zip.
