I am using the coursier tool to prepare my Scala environment. I ran the following:
C:\Users\jaime>cs setup
Checking if a JVM is installed
Found a JVM installed under C:\Program Files\Java\jre1.8.0_271.
Checking if ~\AppData\Local\Coursier\data\bin is in PATH
Should we add ~\AppData\Local\Coursier\data\bin to your PATH? [Y/n] Y
Checking if the standard Scala applications are installed
Found ammonite
Found cs
Found coursier
Found scala
Found scalac
Found sbt
Found sbtn
Found scalafmt
C:\Users\jaime>cs launch scala
Exception in thread "main" java.lang.Exception: C:\Program Files\Java\jre1.8.0_271\java\bin not found

I see that the root cause of the error is that the process is trying to find Java in C:\Program Files\Java\jre1.8.0_271\java\bin
. When I examine the folders, I have this folder structure:
I think the process should be looking for C:\Program Files\Java\jdk1.8.0_271\bin
, not C:\Program Files\Java\jre1.8.0_271\java\bin
.
Is this path something I can manipulate or is this some kind of bug in the coursier tool? I am following the instructions at https://get-coursier.io/docs/cli-launch.
