setup-java@v4 setup for sbt failing on macOS with line 1: sbt: command not found

[Christewart]

This seemingly broke overnight, i'm attempting to setup the build with this

      - name: Setup Scala
        uses: actions/setup-java@v4
        with:
          distribution: 'adopt'
          java-version: '21'
          cache: 'sbt'

and the build is failing with

sbt coverage cryptoTestJVM/test coreTestJVM/test secp256k1jni/test zmq/test appCommonsTest/test asyncUtilsTestJVM/test chainTest/test dlcNodeTest/test appServerTest/test
/Users/runner/work/_temp/5e05e0e3-d7eb-40c9-aacb-dbf00977b77b.sh: line 1: sbt: command not found
Error: Process completed with exit code 127.

EDIT: Note, this only fails on mac builds, linux builds are fine with this setup.

I also encountered the same problem, only for macOS.

brew install sbt workaround works. Looks like even php has disappeared from macOS runners.

SBT is not included in the macOS 13 and macOS 14 Github Hosted Runner. Please refer to this source for confirmation.
If you need to use SBT in your workflow, you can add a step to install it manually.
Here's an example with Homebrew:

- name: Setup SBT
  run: |
    echo ""Installing SBT...""
    brew install sbt

This will install SBT on the runner for the duration of the workflow.

Ran into the same problem, switched to macos-12 for now:

• Use macos-12 because JDK 8 and sbt not available on macos-latest anymore sbt/sbt-pull-request-validator#42

The GitHub Actions macOS 13 and 14 runner images do not come with preinstalled sbt anymore and the GitHub team will not add them back anymore, see these closed issues:

• Add sbt to macOS 13, 14 runner-images#9369
• Add sbt to macOS 13 and macOS 14 runner-images#9837
• Specially this answer

More details can be found here as well:

• Use macos-12 because JDK 8 and sbt not available on macos-latest anymore sbt/sbt-pull-request-validator#42

IMHO this issue can be closed, because it's not the fault of the setup-java actions.
From now on you have to install sbt yourself with brew install sbt

Hello @Christewart, as previously noted, setup-java is functioning properly. The issue has surfaced due to modifications with the macos-13 and 14 runners. We recommend applying the solution we provided to resolve your issue. We're moving forward with closing this issue, but please feel free to contact us if you face any other challenges.
