@vijayemmanuel did you figure this out? Unfortuantely, I have no idea how to determine what my cs/coursier version is.

I can successfully run fetch
, but not install
:wave: I'm new to Scala (started today) and I'm trying to understand how Coursier fit into everything. Would anyone mind explaining a bit? I installed it on my M1 MBP (But I still it runs under Rosetta since it doesn't support Apple Sillicon?) and it required me to have OpenJDK installed. Once installed, I run cs setup
and it installs yet another JDK, including some tools like amm
, sbt
, scala
and scalafmt
. I'm trying to follow the Functional Programming Principles in Scala course on Coursera but ran into problem when they asked me to run sbt
in the example project. Instead of starting the sbt
prompt I got the following error:
~/code/scala-course $ sbt
[info] [launcher] getting org.scala-sbt sbt 1.5.0 (this may take some time)...

After some debugging on my part, it looks like Coursier installed sbt
, version 1.6.2
and the project had configured sbt.version=1.5.0
. Changing this to sbt.version=1.6.2
instead, solved the problem.
.bash_profile
for a vert specific JDK.
~/.local/share/coursier/bin
in your PATH
@Flowdalic When I run cs setup
it asks to put things into .profile
and .bash_profile
. Specifically the following:
# >>> JVM installed by coursier >>>
export JAVA_HOME="/Users/kevin/Library/Caches/Coursier/arc/https/github.com/adoptium/temurin18-binaries/releases/download/jdk-18%252B36/OpenJDK18U-jdk_x64_mac_hotspot_18_36.tar.gz/jdk-18+36/Contents/Home"
# <<< JVM installed by coursier <<<
# >>> coursier install directory >>>
export PATH="$PATH:/Users/kevin/Library/Application Support/Coursier/bin"
# <<< coursier install directory <<<
Adding /Users/kevin/Library/Application Support/Coursier/bin
to my PATH
is fine, but the JAVA_HOME
is explicit. If I'm supposed to use Coursier to manage different versions of the JVM, I don't see how this fits into that.
cs java --jvm 11 --env
JAVA_HOME
that coursier added to my .bash_profile
I can't use the apps anymore.
JAVA_HOME
to the output of cs java-home
again.
scala
now spits out The operation couldn’t be completed. Unable to locate a Java Runtime.

.
JAVA_HOME
set, just not with a value provided by couriser
.envrc
file that sets things up using cs java --env
but I'm still confused how things is intended to work.
cs list
that lists installed apps)?

for this terminal only
Hello, I'm totally new to Scala so please forgive me in advance if I'm slow on the uptake here... I installed coursier via Homebrew. Then I added a channel from Maven with cs channel --add https://repo1.maven.org/maven2/io/gatling/highcharts/gatling-charts-highcharts-bundle/maven-metadata.xml
. It showed the channel as properly installing. So far so good. But then when I try to install or resolve the package, I get:
cs resolve gatling-charts-highcharts-bundle
Exception in thread "main" java.lang.Exception: java.lang.Exception: Error decoding /Users/daniel/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/io/gatling/highcharts/gatling-charts-highcharts-bundle/maven-metadata.xml (https://repo1.maven.org/maven2/io/gatling/highcharts/gatling-charts-highcharts-bundle/maven-metadata.xml): Unexpected content found: <?xml version="1.0" encoding="UTF-8"?>
Any ideas what I'm doing wrong here? Thanks.
java-home
command to print the path for the linux-musl
version of the JDK on Alpine?
