CoursierConfigModule

Reads coursier environment variables and Java properties

This module reads environment variables and Java properties, and uses them to get default values for a number of coursier parameters, such as:

• the coursier cache location, read from COURSIER_CACHE in the environment and coursier.cache in Java properties. It is recommended to use an absolute path rather than a relative one.

• the coursier archive cache location, read from COURSIER_ARCHIVE_CACHE in the environment and in coursier.archive.cache in Java properties.

• credentials, read from COURSIER_CREDENTIALS in the environment, and coursier.credentials in Java properties. Its format is documented here: https://github.com/coursier/coursier/blob/701e93664855709db38e443cb7a19e36ddc49b78/doc/docs/other-credentials.md

• TTL for snapshot artifacts / version listings / etc., read from COURSIER_TTL in the environment and coursier.ttl in Java properties. This value is parsed with scala.concurrent.duration.Duration, and accepts formats like "5 hours", "1 day", etc. or just "0".

• default repositories, read from COURSIER_REPOSITORIES in the environment and coursier.repositories in Java properties. It can be set to values like "ivy2Local|central|https://maven.google.com". Its format is documented here: https://github.com/coursier/coursier/blob/701e93664855709db38e443cb7a19e36ddc49b78/doc/docs/other-repositories.md

• mirror repository files, read from COURSIER_MIRRORS and coursier.mirrors, whose file they point to should contains things like

  google.from=https://repo1.maven.org/maven2 google.to=https://maven.google.com

Environment variables always have precedence over Java properties.
