<br>
Maven style repositories to resolve artifacts from.
Coursier will resolve these repositories in the order in which they are specifed, and re-ordering repositories will cause artifacts to be re-downloaded. This can result in artifacts in lockfiles becoming invalid.

Known versions to verify downloads against.
Each element is a pipe-separated string of `version|platform|sha256|length`, where:
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.

<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.
