Known versions to verify downloads against.

Each element is a pipe-separated string of version|platform|sha256|length, where:

  • version is the version string
  • platform 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 by shasum -a 256
  • length is the expected length of the download file in bytes, as emmitted by wc -c

E.g., 3.1.2|macos_x86_64|6d0f18cd84b918c7b3edd0203e75569e0c7caecb1367bbbe409b44e28514f5be|42813.

Values are space-stripped, so pipes can be indented for readability if necessary.

url_platform_mapping​

--coursier-url-platform-mapping="{'key1': val1, 'key2': val2, ...}"
PANTS_COURSIER_URL_PLATFORM_MAPPING
pants.toml
[coursier.url_platform_mapping]
key1 = val1
key2 = val2
...
default: 
{
  "linux_arm64": "aarch64-pc-linux",
  "linux_x86_64": "x86_64-pc-linux",
  "macos_arm64": "x86_64-apple-darwin",
  "macos_x86_64": "x86_64-apple-darwin"
}

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​

--coursier-url-template=<str>
PANTS_COURSIER_URL_TEMPLATE
pants.toml
[coursier]
url_template = <str>
default: https://github.com/coursier/coursier/releases/download/{version}/cs-{platform}

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-&#123;version&#125;-&#123;platform&#125;.zip.
