[
  "v2.1.42|darwin|69d6b1b1009b00dd14a3a9f19b72cff818a713ca44b3186c9b12074b2a31e51f|3613838",

]

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 [darwin,linux],
  • 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|darwin|6d0f18cd84b918c7b3edd0203e75569e0c7caecb1367bbbe409b44e28514f5be|42813.

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


url_template

--download-pex-bin-url-template=<str>
PANTS_DOWNLOAD_PEX_BIN_URL_TEMPLATE
default: https://github.com/pantsbuild/pex/releases/download/{version}/pex

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:// URL.

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.


url_platform_mapping

--download-pex-bin-url-platform-mapping="{'key1': val1, 'key2': val2, ...}"
PANTS_DOWNLOAD_PEX_BIN_URL_PLATFORM_MAPPING
default: {}

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 {&quot;darwin&quot;: &quot;apple-darwin&quot;, &quot;linux&quot;: &quot;unknown-linux&quot;}, and run Pants on Linux, then {platform}` will be substituted in the --url-template option with unknown-linux.
