Hi - new to Coursier and Scala! i'm looking for a self-contained example / "hello world" on Coursier using Gradle as a build tool (i have to use Gradle because it's used at my company with Java). Specifically I can use Coursier launch using say 'cs launch scala:2.13.15 -- foo.scala' and I want to know how to use 'cs launch' with Gradle.
hey @ghc1001, what you're trying to do doesn't really make sense to me. Are you trying to just run your build? If so, then you'd want to do that with gradle, not coursier
or are you trying to use coursier to launch a Scala application that has already been published?
I want to know how to use 'cs launch' with Gradle.
Essentially, you don't
you use gradle to launch a gradle project and you can use coursier to launch a published jar
hey @ckipp:matrix.org, thanks for your reply! i should have clarified. to run my build, yes - i want to use gradle. to build, i need to use 'cs launch' - what i really want to do is swap out the scala compiler in gradle's build process with 'cs launch scalac:2.xxx' or 'cs launch scalac:3.xxx' because that's what my company provides ('cs' is configured to hit an internal artifactory repo so the 'cs launch' pattern is not something i can change). that also means that 'cs' would do the fetching during the build, not gradle. so you're right, i want coursier to launch the internally-published JARs for the scala compiler (and fetch any dependencies internally) under gradle (if that's possible). and then use gradle as usual for run my build.
what i really want to do is swap out the scala compiler in gradle's build process with 'cs launch scalac:2.xxx' or 'cs launch scalac:3.xxx' because that's what my company provides
I guess this is the part the confuses me with your use case. cs launch will have nothing to do with gradle. At the point that you're using launch, gradle is no longer in the picture
do you mean you have two artifacts and you want to be able to cs launch both the Scala 2 artifact and the Scala 3 artifact?
what exactly are you trying to launch?
@ckipp:matrix.org i'm trying to launch both the Scala 2 compiler (for a 2.x build) and the Scala 3 compiler (for a 3.x build), yes. i have two ways to go: 1) with gradle, where i need to specify the dependencies in the build.gradle - something like dependencies {
implementation "org.scala-lang:scala-library:2.13.1"
scalaCompilerPlugins "org.typelevel:kind-projector_2.13.1:0.11.0"
}
implementation "org.scala-lang:scala-library:2.13.1"
scalaCompilerPlugins "org.typelevel:kind-projector_2.13.1:0.11.0"
}
@ckipp:matrix.org or 2) with coursier, where i can use 'cs launch scalac:2.13.1 -- foo.scala'
both methods work (the dependencies are fetched). and here's where i am beyond my depth - i don't know if i can tell gradle to use 'cs launch scalac:2.13.1 -- foo.scala' to build. i think (i could be wrong) that gradle fetches itself and you can only specify dependencies using e.g. the above Groovy code; you can't tell gradle to go do things with coursier. for various internal reasons the coursier way is "cleaner" - but using it alone i'd have to dump Gradle, so i'm trying to get the best of both worlds... hope that makes more sense?
this all seems very odd
and I'm still not 100% sure what you mean
Hi @alexarchambault. How are we supposed to create a
Dependency without access to MinimizedExclusions in coursier 2.1.0-M7?
It's private to
coursier package
In Mill, I have the additional problem of pickling and unpickling it to json.
Anyone able to build coursier locally? I tried on a fresh clone today and I keep getting

Hi all,
Is the installation of Bloop with Coursier supposed to install the zsh auto-completion config?
I'm new to both those tools, so maybe I'm just misunderstanding something.
I installed Bloop as described in the doc (https://scalacenter.github.io/bloop/setup#universal) on Linux, everything seems to work, except that the
I then found the relevant file in the bloop repo (https://github.com/scalacenter/bloop/blob/main/etc/zsh-completions) and copied it manually to
Is Coursier supposed to have created that file, in which case maybe I should open a issue on the Coursier repo?
Or should the Bloop install documentation be updated to let people know they should download the file manually?
Or something else?
Thanks in advance :)

Does coursier support pushing to private gitlab repositories? For SBT we have the plugin sbt-gitlab (https://github.com/gilcloud/sbt-gitlab) that sets custom http header for authenticating. As of the docs it explicitly mentions that we need to set
useCoursier := false. Does coursier support private gitlab repos?
Hey guys, I saw 2.1.0-RC5 has been released but there is no Linux aarch64 version in the releases...
Hi all, I've got an internal library that's not versioned in the traditional sense, it exists in two versions "foo" and "bar". I want sbt/coursier to treat it like a Snapshot, ie. don't cache it. According to https://get-coursier.io/docs/ttl, one way to do it would be to add the -SNAPSHOT suffix, so we could change our versions to "foo-SNAPSHOT" and "bar-SNAPSHOT". Sbt also has a
withIsChanging function, can I use that instead? So e.g. libraryDependencies += ("internal" %% "library" % "foo").withIsChanging(true)
