(the --scala argument is supported for cs launch etc, but not for cs install)
Matthias Lüneberg
Hi, is it planned to support aarch64 as an architecture in coursier? I found there is a guard to only explicitly allow "x86_64" | "amd64" here: https://github.com/coursier/coursier/blob/master/modules/jvm/src/main/scala/coursier/jvm/JvmIndex.scala#L82

@alexarchambault I want to test coursier/coursier#1834 haven't broken scala-runners. Is it intentional that the homebrew formula is still on release 24 and/or that there's no native cs build associated to the releases?

installation process hanging here for really a long time
while brew installs calacenter/bloop/bloop
I thought it might be network issue
I have a proxy
how can i pass proxy configurations to coursier cli?
by setting a system variable
Jack Koenig
In the CLI, is there anyway to make the downloading log (eg. Downloading https://repo1.maven.org/maven2/org/...) go to stdout instead of stderr?
2 replies
Anton Sviridov
do you have access to shell's redirection?
Jack Koenig
Yes, redirecting all of stderr to stdout isn't what I want in case there are real errors
Is it possible to install specific version of application? Something like coursier install bloop --version 1.4.1

How is the sbt installed by Coursier (for 1.4) different than that provided by SBT website? The Coursier one doesn’t seem to accept flags. I used to be able to write sbt -help but that doesn’t work in the version provided by coursier.

Hey all, I want to use cs install for my application. Is there any way to pass java options to cs installed application? . I see java options support is there for cs launch https://get-coursier.io/docs/next/cli-launch.html#java-options. But I did not see any documentation for providing java options after cs install

Hi @alexarchambault . Maybe there was a problem publishing releasing 2.0.2 of https://github.com/coursier/sbt-coursier/releases? I dont see 2.0.2 in https://repo1.maven.org/maven2/io/get-coursier/lm-coursier-shaded_2.12/

We are trying cs launch and cs install for our application. We have followed steps below:

  1. Sbt my-app/publishLocal
  2. Cs channel —add ‘<channel-url>’
  3. Cs launch my-app:0.1.0-SNAPSHOT
    Works as expected. cs launch resolves in ivy local as well as repositories specified in channel.

When we try to install launcher for snapshot version using,
Cs install my-app:0.1.0-SNAPSHOT it gives resolution error. It tries to resolve only in repositories specified in channel and not in default repositories like ivy. We also tried giving ivy2Local as an option to install command. Cs install -r ivy2Local my-app:0.1.0-SNAPSHOT also gives similar error.

We want to validate if this is as per intended usage of cs install? If not, what is possible way to install snapshot version of app?

(from https://gitter.im/lihaoyi/mill; do you want me to raise something official re. this? response was that this is a bug w/ coursier install of mill 0.8.0...)

have been struggling a lot with this error recently using mill 0.8.0 (installed by coursier):

$ mill foo.run
[28/36] foo.finalMainClass
1 targets failed
foo.finalMainClass No main class specified or found

on pretty much every mill project i create or try to convert from sbt (in two environs, macOS and Debian).

simplest example, where mill.compile and mill.test are fine, is:

import mill._, scalalib._

object foo extends ScalaModule {
  def scalaVersion = "2.13.1"

  object test extends Tests {
    def ivyDeps = Agg(ivy"com.lihaoyi::utest:0.7.4")
    def testFrameworks = Seq("utest.runner.Framework")
package foo

object Example {
  def main(args: Array[String]): Unit = {
  def hello(): String = "Hello World"
package foo

import utest._

object ExampleTests extends TestSuite {
  def tests = Tests {
    test("hello") {
      val result = Example.hello()
      assert(result == "Hello World")

Is it possible to specify a JRE when using a coursier launcher? For example can I do sbt --something to run coursier-installed sbt with a named JRE?
$ cs launch --help | grep jvm
  --jvm  <string?>
  --jvm-dir  <string?>
  --system-jvm  <bool?>
  --jvm-index  <string?>
@tpolecat also see cs java-home --help
idk anything more than that. I assume sbt installed by cs is equivalent to cs launch sbt
Rob Norris
$ sbt --jvm 8 console
[info] Loading global plugins from /Users/rnorris/.sbt/1.0/plugins
[info] Loading settings for project atto-build-build-build-build from metals.sbt ...
[info] Loading project definition ...
[error] Expected ';'
[error] --jvm
[error]      ^
I was hoping for something like that.
@tpolecat I mean try cs launch --jvm 8 sbt console
The cs-installed sbt doesn't seem to even have a --help screen like the usual launcher script
Rob Norris
Ok i didn't know you could do cs launch <app>. That works, thanks.
Oh I see, it looks at the default channel, not at the installed apps.
Alexandre Archambault
It should look at the channels added with cs install --add-channel, and also accepts new ones via --channel.
I'd like to have the installed launchers accept a --jvm channel option, but they don't for know.

Hello, I am a beginner with Scala and I would like to use cs setup to install the Scala dev environment. But how can I specify, that it should use Scala 3.0.0-M1 ? I have read through the documentation and I can specify the java version which should be used, but haven't found any option for the scala version. Thanks for help.
