Pure Scala Artifact Fetching

Hi all, when I try to symlink ~/.local/share/coursier/bin/cs to ~/bin/cs then running ~/bin/cs fails to run. The path of .cs.aux is being 'resolved' via dirname which resolves the dirname of the symlink, not to the actual cs under ~/.local;

looking at ~/.local/.../cs adding readlink $(dirname $(readlink -f "$0")) solves this issue

Is --progress supposed to completely hide any progress at all?

Like should I be seeing this with progress set to false?

Hi everyone :-)
Does coursier need special treatment to update GraalVM to 21.0.0 ? If so, is it tracked somewhere?

I have a question I wasn't able to answer reading the docs, how do I set the scala version for zinc? For example, when I try to download zinc, it tells me it ca't find a scala version suffix for zinc, but I have entered it right here

cs fetch org.scala-sbt::zinc_2.12:1.4.4
Exception in thread "main" coursier.install.AppArtifacts$ScalaDependenciesNotFound: Can't find a scala version suffix for org.scala-sbt::zinc_2.12:1.4.4

Shane Delmore

@ShaneDelmore

Although cs complete can find it

❯ cs complete org.scala-sbt:zinc_2.12
zinc_2.12

@lefou

@ShaneDelmore Either add the _2.12 OR the double colon :: between org and name, but not both.

Shane Delmore

@ShaneDelmore

Thanks @lefou, I never would have figured that out on my own.

And if I use ::, is there a way to set scala version, or does it just always use 2.13?

That's just a question out of curiousity, the single colon worked great.

Tobias Roeser

@lefou

Can't tell you where the default comes from. I guess, it's the scala version used by ammonite, so atm 2.13.x

Sorry, I was asuming your using ammonite, but actually I don't know the context, so I can't tell you

Shane Delmore

@ShaneDelmore

No ammonite, just cs fetch org.scala-sbt::zinc_2.12:1.4.4

Or, in this case, when doing cs fetch org.scala-sbt::zinc:1.4.4 how does it decide which scala version?

No worries if you don't know.

Exception in thread "main" coursier.install.AppArtifacts$ScalaDependenciesNotFound: Can't find a scala version suffix for org.scalameta::scalafmt-cli:latest.release (likely a non existing module or version)

I'm getting this exception when I'm trying coursier fetch with a private repository. Anyone has any idea what might be going on?

The interface for Scala Native has changed a bit in 0.4.0 although the old interface still works but is deprecated. I didn't see any issues or PRs - is this update being considered?

Siddhant Sanyam

@siddhant3s

I guess I'm not understanding coursier's repo resolution at all:
I've set my mirrors.properties to point central.to correctly my local maven proxy. On top of that, I'm passing -r https://maven.company.com/nexus/content/groups/public --no-default to coursier. Even then... it's trying to connect to repo1.maven.org. I don't understand why.

Hello, when using coursier/cache-action, we're seeing warnings like reserveCache failed. Is it OK? Or is something going wrong? /cc @mijicd

Hi folks. First off, fantastic tool. Coursier bootstrap is amazing! I've been noticing that recent versions of coursier have been embedding the primary jar file in the bootstrap binary. Is there a way to disable this feature?

1 reply

(or perhaps am I using it wrong?)

Specifically, I have a little bit of a hack that relies on python's ability to execute a tar file to package python code with my jar, and recently I've noticed that bootstrap binaries are seeing the classloader reading from path/to/bootstrap!coursier/bootstrap/launcher/jars/___.jar instead of the typical file:/path/to/__main__.py or jar:/path/to/___.jar

Hmm... is coursier automatically packaging files that aren't visible to a global resolver? If so, is there a command-line flag that will turn this behavior into an error?

I have been trying to get the Scala tool set to work behind a corp proxy with basic auth. The following meta issue was added - scalameta/metals#2485 I did some analysis starting at the very beginning.

Hi, I'm trying to use a local maven repo. When I do coursier fetch scalafmt it fails with Caused by: coursier.install.AppArtifacts$ScalaDependenciesNotFound: Can't find a scala version suffix for org.scalameta::scalafmt-cli:latest.release (likely a non existing module or version)

However when I write the exact version number (after consulting the internet on whatever the latest version, couriser succeeds):

[siddhant@localhost ~] coursier fetch org.scalameta:scalafmt-cli_2.13:2.7.5

Does anyone have ideas as to what might be going on or how do I debug this?

I tried coursier fetch org.scalameta::scalafmt-cli:2.7.5 but that doesn't work either (notice the ::)

I was trying to see if I could make some changes using this as a guide. If I look at the script it looks like it calls main in Coursier but if I put some System.err.println in there I see nothing so I am thinking I am missing something.

Hi, I'm using Homebrew 3.0.0 and tried brew install coursier/formulas/coursier and brew tap coursier/formulas. Each time, I get these errors:

Error: Invalid formula: /usr/local/Homebrew/Library/Taps/coursier/homebrew-formulas/coursier.rb
coursier: Unsupported special dependency :java
Error: Cannot tap coursier/formulas: invalid syntax in tap!

What's the difference between bootstrap --standalone and bootstrap --assembly ?

Hi @lolgab

Does coursier need special treatment to update GraalVM to 21.0.0 ? If so, is it tracked somewhere?

Coursier uses a JSON file with an index of JVMs from Jabba project. Version 21.0 of GraalVM was only recently added there. For some reason Coursier doesn't pick this up automatically, but if you pass an additional option, the new GraalVM can be used. The option is

--jvm-index https://raw.githubusercontent.com/shyiko/jabba/master/index.json

Hi guys

anybody knows how to get coursierDependencyTree by specific scope/s?

i can see support when i run sbt test:coursierDependencyTree but it is not working the same for
provided/import/runtime..
just for test/compile..
any idea where i can find documentation about this?

Mark T. Kennedy

@mtk

is there a way to ask coursier to tell me what could be updated without actually updating anything?

StinkyLord

@StinkyLord

is this forum even alive?:D

Przemek Pokrywka

@przemek-pokrywka

@StinkyLord semi-alive. I may be wrong but Coursier doesn't support the concept of scopes at the moment I think.

StinkyLord

@StinkyLord

it's weird because this sbt test:coursierDependencyTree syntax work fine.. and i checked the source code it has support for scopes.. i wonder why its not official in the docs

Can anyone see why this might be giving me the below errors?

It appears to be ignoring the command line args?

Given a path to an artifact, is there a simple way to get the path to the repo subdirectory? E.g. I have the downloaded

/Users/jast/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/org/jetbrains/scala/scala-compiler-indices-protocol_2.13/1.0.13/scala-compiler-indices-protocol_2.13-1.0.13-javadoc.jar

and want the /Users/jast/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/ and org/jetbrains/scala/scala-compiler-indices-protocol_2.13/1.0.13/scala-compiler-indices-protocol_2.13-1.0.13-javadoc.jar portions separately?

Hi, seems like Coursier cannot resolve the latest version of the netty-transport-native-epoll library for Mac and Linux:

When I add "io.netty" % "netty-transport-native-epoll" % "4.1.60.Final” dependency to the build, Coursier fails retrieveing the artifact with the following error:

 Caused by: lmcoursier.internal.shaded.coursier.cache.ArtifactError$NotFound: not found: https://repo1.maven.org/maven2/io/netty/netty-transport-native-epoll/4.1.60.Final/netty-transport-native-epoll-4.1.60.Final-linux-aarch64.jar

Cause: coursier tries to download the artifact with linux-aarch64 prefix, while the actual prefix is linux-aarch_64

Is there any way to configure the correct prefix for transitive dependency?
