Is this supposed to work?
cs launch scala3-compiler:3.0.0-RC1
2 replies
Hi, how can I do the equivalent of
cs launch from code, capturing stdout and stderr?

I'm having a hard time understanding why this doesn't work
cs complete -r sonatype:snapshots org.scalameta:metals_2.12:
this still just prints out all of the Metals stable versions and doesn't capture what I'd expect it to from here:
https://oss.sonatype.org/content/repositories/snapshots/org/scalameta/metals_2.12/maven-metadata.xml
I believe I even asked this before, but I've never successfully been able to list out the actual snapshot versions of Metals that exist here, are able to be pulled, but never show up in complete
any idea how to see these or what I'm doing wrong here?
Can anyone see anything I'm doing obviously wrong here?

pray tell - is there a way to print each and every http request coursier issues from inside sbt (preferrable 1.4.9, i have some other issue with 1.5.0 i don't want to deal with right now)?
i have interesting issues with a locally hosted artifactory which gives me quite unexpected 403 forbidden responses, and i need more input to think about.

another question: am i right in guessing that OkHttpDownload is the one used in sbt by default, and it does send basic authentication headers right from the beginning, without waiting for a status 401 first? if that's the case, it would be worth a comment in sbt/sbt#5556

Hello Folks, I am currently migrating a project from sbt 1.1 to sbt 1.4, and upon compilation, I get this issue.

)When I disable coursier, the project compiles successfully and therefore I believe the issue is coming from a coursier incompatability. Can someone please help? I've been beating my head against this for a while now
It seems that the Coursier launcher for sbt doesn't work with 1.5.0 … it's not clear to me who is in charge of keeping it updated, or really whether it should exist at all given the complexity of the standard launcher script. It seems to me that resolving this is a blocker for Coursier becoming the standard way to manage Scala tooling. Maybe this would be a good Scala Center project, I don't know.
Does anyone have any better-formed thoughts about this?
Hi all. Anyone know if it is possible to get the version number of an app that would be resolved by cs install or cs bootstrap?
For example, for apps declared with latest.stable version in a channel such as 'scala' from the 'core' channel, is there any way to get the version that would be fetched by cs bootstrap scala?
Oh, my previous message... just ignore it; I don't see how to remove it.

Hello all, I'm curious as to how 'complete' (https://get-coursier.io/docs/cli-overview.html#complete) does what it does, because it seems incredible (how does it work out all the artifacts for a group?! Where is the Maven data for that!?). I was trying to dig through the code (looking at eg https://github.com/coursier/coursier/blob/382250d4f26b4728400a0546088e27ca0f129e8b/modules/core/shared/src/main/scala/coursier/maven/MavenComplete.scala#L16 ) but was slightly hamstrung because IntelliJ fails to import the sbt project (I don't know if there's any special guidance on etting IntelliJ to do this, couldn't see any in https://get-coursier.io/docs/dev-contributing ).
Oh wow - to answer my own question about "how does it work out all the artifacts for a group?" (specifically I was interested in Maven Central) - Coursier parses it (https://github.com/coursier/coursier/blob/382250d4f2/modules/util/jvm/src/main/scala/coursier/util/WebPageCompatibility.scala#L9-L14) from raw HTML directory listings, like eg https://repo1.maven.org/maven2/org/typelevel/ . Those HTML directory listings were the best source of that information I'd been able to find (possibly the only source, apart from https://search.maven.org/solrsearch/select) but I was still a bit surprised that they are the best source of that information. Those HTML pages haven't changed format for a long time, but I'm assuming they aren't a formal API, or are they? I wonder if aether/Maven Artifact Resolver Provider do this. I mean, this approach works fantastically well, I'm just slightly unnerved.
If I'm not mistaken the html listing page is actually a backup that coursier uses if it's unable to locate the maven-metadata.xml file for a project
most of the time I believe the full version information is simply parsed from the maven-metadata file both for the complete and resolve functionality
That makes sense! I guess it can definitely refer to maven-metadata.xml when an artifact coordinate is specified (eg
org.typelevel:cats-core_2.13) which most be the most common kind of question it faces, but there's no usable maven-metadata.xml at the group level (eg https://repo1.maven.org/maven2/org/typelevel/maven-metadata.xml doesn't exist) - so if you want to find all the artifacts that live under a group id (eg org.typelevel) then there's no choice but to parse the HTML out of the directory listing page. It's a much rarer question though - I'm currently interested in it, but I guess it's not going to be an essential part of eg resolving all the dependencies of build!
@phendric I think you should use
https://git.io/coursier-cli-linux or the thing from https://alexarchambault.github.io/posts/2020-09-21-cs-setup.html#managing-applications that tries to judge which os you are on, but not sure how that works on WSL2/Ubuntu20.04: curl -fLo cs https://git.io/coursier-cli-"$(uname | tr LD ld)" so perhaps safer to just use curl -fLo cs https://git.io/coursier-cli-linux
I am having trouble with using the FileCredentials class to set auth for a repo (it does not like my Windows path to a credentials file), so I thought I'd use the method described in the documentation instead, but no file location for the credentials.properties file is given for Windows. I've tried putting it under users/username/.config etc but no dice thus far. I'm using whatever version of coursier that comes with the Scala Metals plugin on VSCode
I should be able to access the properties using sys.props.get if they're properly loaded yeah?

I created my own and app and published to a local repository. I also created a descriptor. Everything works fine if I give the exact version in the descriptor. But if I use
latest.release or latest.stable, it is not getting resolved. Do I need to do something for that? Thanks in advance.

Trying to update Coursier to test scala3 was very frustrating, I tried cs install cs and got the same error. I don't understand why this keeps failing as this is the recommended way to install scala3. I'm going back to sbt for now. Is somebody able to help:

Btw, this happened in MacOS Catalina
@raul782 As a fallback you can just download https://github.com/lampepfl/dotty/releases/download/3.0.0/scala3-3.0.0.zip and put the extracted files in e.g. ~/scala3 and put the ~/scala3/bin on your path and you are ready to go. But perhaps it does not work if the above error is a symptom of problems with Java installation, then I'd recommend you to install JDK 11 from here https://adoptopenjdk.net/
I see it exists in the index - but I don't know how to indicate that it should be installed:

cs java --jvm zulu:16 --setup installs the x64 version
When I read the docs here https://get-coursier.io/docs/cli-installation I get the impression that coursier should fix my path. But when I follow the instructions it only prints a message that I should do it myself. Can coursier patch my path? If not then that page should perhaps be clarified so it is obvious that I need to do this myself. (I'm currently considering using cs for my beginner programmer students and unfortunately I think the instructions are a bit intimidating for a beginner so if we are going use cs I need to give them something easier to follow that does not assume any deeper knowledge of cmd/bash/terminal/console/powershell... etc)
Does anyone know how cs can install a scala3 runner? WIth the instructions here https://www.scala-lang.org/download/scala3.html you get scala3-compile and scala3-repl on your path but not any scala3 runner on your path to run your compiled programs. So how to run your programs compiled with cs scala3-compiler?
I think it should look for JAVA_OPTS env var to find the Java -DhttpProxy... stuff but I couldn't find it looking for that in the CLI code.
I am no authority because I could even get the build to work because I started to look into this. I found a specific thing coursier or bloop couldn't do related to redirect and a proxy with basic auth.
