Can't use different version for native CLI #4571
Description
This issue is observable in the following configuration
- latest version of CLI and previous version in
.scalafmt.conf
Configuration (required)
version = 3.8.3
runner.dialect = scala3
...
rewrite.scala3.convertToNewSyntax = true
rewrite.scala3.removeOptionalBraces = falseCommand-line parameters (required)
When I run scalafmt via CLI like this: scalafmt --diff-branch origin/master
Steps
Given a GitHub workflow
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: coursier/setup-action@v1
with:
jvm: temurin:21
apps: scalafmt
- run: scalafmt --diff-branch origin/masterProblem
When running scalafmt when a PR is raised via
Run scalafmt --diff-branch origin/master
scalafmt --diff-branch origin/master
shell: /usr/bin/bash -e {0}
env:
JAVA_HOME: /home/runner/.cache/coursier/arc/https/github.com/adoptium/temurin21-binaries/releases/download/jdk-21.0.5%252B11/OpenJDK21U-jdk_x64_linux_hotspot_21.0.5_11.tar.gz/jdk-21.0.5+11
COURSIER_BIN_DIR: /home/runner/cs/bin
I get the following error

Expectation
I expect scalafmt to format the code or just do nothing
Run scalafmt --diff-branch origin/master
scalafmt --diff-branch origin/master
shell: /usr/bin/bash -e {0}

Reformatting...Workaround
I've found that by setting scalafmt version in .scalafmt.conf to the latest 3.4.2-RC2 the issue doesn't happen anymore
Notes
My assumption is that coursier pulls the latest scalafmt-cli as it's configured to latest.release
This only started happening yesterday, probably after 3.8.4-RC2 release, because there were no problems when 3.8.4-RC1 was the latest.
The same issue happens when running scala-steward from GitHub Actions when it tries to reformat changes
