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 emitted 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.

<br>
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.
</div> <br>
<div style="color: purple"> <h3><code>url_platform_mapping</code></h3> <code>--pex-cli-url-platform-mapping="{'key1': val1, 'key2': val2, ...}"</code><br> <code>PANTS_PEX_CLI_URL_PLATFORM_MAPPING</code><br> </div> <div style="padding-left: 2em;"> <span style="color: green">default: <code>{}</code></span>
<br>
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.
