coursier
A dependency resolver for the Maven ecosystem.
Backend: pants.backend.experimental.java
Config section: [coursier]
Basic options
repos
--coursier-repos="['<str>', '<str>', ...]"
PANTS_COURSIER_REPOS
[coursier]
repos = [
'<str>',
'<str>',
...,
]
[ "https://maven-central.storage-download.googleapis.com/maven2", "https://repo1.maven.org/maven2" ]
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:
- `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.

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
[coursier]
url_template = <str>
https://github.com/coursier/coursier/releases/download/{version}/cs-{platform}.gz
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.
