Coursier

coursier 1.1.0-M10 was just released. This is the first release of coursier while it's new website is up and running, and sbt-ci-release handles publishing, from Travis CI.

Note that this is a milestone release, not necessarily aiming at retaining binary / source compatibility of the API with earlier versions. If you're using coursier via its API, it is recommended to stay on former versions unless you're interested in the very latest features and are ready to update the way you use the API in later versions.

New launcher URL

One notable change of this release is that the launchers of coursier are now being pushed to GitHub release pages rather than in the master branch of the coursier git repository. The URL to download it thus changes.

--what-depends-on option

Add a --what-depends-on option to the resolve command, to quickly know which dependencies bring a particular dependency (#997), e.g.

$ coursier resolve \
    --what-depends-on org.htrace:htrace-core \
    org.apache.spark:spark-sql_2.12:2.4.0
  Result:
└─ org.htrace:htrace-core:3.0.4
   ├─ org.apache.hadoop:hadoop-common:2.6.5
   │  └─ org.apache.hadoop:hadoop-client:2.6.5
   │     └─ org.apache.spark:spark-core_2.12:2.4.0
   │        ├─ org.apache.spark:spark-catalyst_2.12:2.4.0
   │        │  └─ org.apache.spark:spark-sql_2.12:2.4.0
   │        └─ org.apache.spark:spark-sql_2.12:2.4.0
   └─ org.apache.hadoop:hadoop-hdfs:2.6.5
      └─ org.apache.hadoop:hadoop-client:2.6.5
         └─ org.apache.spark:spark-core_2.12:2.4.0
            ├─ org.apache.spark:spark-catalyst_2.12:2.4.0
            │  └─ org.apache.spark:spark-sql_2.12:2.4.0
            └─ org.apache.spark:spark-sql_2.12:2.4.0

(Adapted from the coursierWhatDependsOn command of sbt-coursier, itself inspired by the whatDependsOn command of sbt-dependency-graph.)

coursier-bootstrap library

Move the bootstrap generation logic of the bootstrap command to a separate standalone library (io.get-coursier::coursier-bootstrap:1.1.0-M10, #991).

Leaking of classes from the bootstraps

Prevent classes from the coursier launcher or of the logic of coursier bootstrap to leak in apps launched via the fetch command or bootstrap generated via the bootstrap command (#983 - coursier.CachePath or the classes of directories could leak in the launched application classpath.)

LDFLAGS for scala-native executable generation

Accept linking flags via LDFLAGS in the environment, when generating scala-native executables (#981).

Other

  • force fetching artifacts from the CLI with --force-fetch, even if resolution failed (#980)
  • fix JARs landing in the wrong classloader, when using the classloader isolation capabilities of the bootstrap command (#982)
  • refactoring of the cache module (#984)
  • switch to scala 2.12.8 (#986), add support for scala 2.13.0-M5
  • switch to fastparse 2 (#990, still shaded so that it doesn't appear as a dependency to downstream users of coursier)
  • allow to adjust the default number of parallel downloads via the coursier.parallel-download-count Java property (#994)
