S3 Coursier Plugin for use with Pants

S3 Coursier Plugin

Coursier plugin adding support for S3 dependency resolution. The main purpose of this fork is to enable S3 resolution in Pants 1.27.0+. Also, the original 0.1.0 doesn't work with Coursier 1.1.0-M14 (used by Pants 1.27.0).

This fork uses standard s3:// scheme unlike the original (which uses s3c://), so it's probably not compatible with fm-sbt-s3-resolver.

Credentials

• Environment

AWS_ACCESS_KEY_ID="myKey"
AWS_SECRET_ACCESS_KEY="myVeryS3cret"
AWS_DEFAULT_REGION="eu-east-1"

• File

File named .s3credentials can be placed in one of the following locations: current directory, $HOME, $HOME/.sbt, $HOME/.coursier

# Credentials
accessKey = myKey
secretKey = myVeryS3cret

# Region
region = eu-east-1

Usage

$ sbt publishLocal
$ coursier bootstrap coursier:1.1.0-M14 rtfpessoa:coursier-s3_2.12:0.2.0-SNAPSHOT --assembly -o coursier-1.1.0-M14-s3.sh
$ tail -c +458 coursier-1.1.0-M14-s3.sh > coursier-1.1.0-M14-s3.jar

Now you can tell Pants to use your custom Coursier version instead of the official one:

[coursier]
repos = """
+[
    's3://s3.amazonaws.com/your-bucket/some/path',
  ]
"""
bootstrap_jar_urls = ['file:///path/to/coursier-1.1.0-M14-s3.jar']

You may need to rm "$HOME/.cache/pants/bin/coursier/1.1.0.cf365ea27a710d5f09db1f0a6feee129aa1fc417/coursier if Pants has already downloaded the official JAR.
