Quick question: I want to build an app running on desktop (mac, win, linux). The issue I met is the package I ran build on mac cannot run on windows well (some class def not found)

I guess, you have to build on each host separately.

I have to do so now..

It looks like it bundles the runtime according to the current host.

Yep, thx Ivan

Yes, it does. For the macOS version you need to execute

createDistributable

on a Mac.

Thx Stefan ~ I will have a try later

@Stefan Oltmann would you happen to have an example with the mac/windows github actions with compose executable build that we could access? thanks

It's really simple. Windows for example has this entry in my `ci.yml`:

windows:
  name: Windows
  needs: build
  runs-on: windows-latest
  timeout-minutes: 60
  steps:
    - name: Checkout workspace
      uses: actions/checkout@v3
    - name: Gradle Cache
      uses: actions/cache@v3
      with:
        path: |
          ~/.gradle/caches
          ~/.gradle/wrapper
          ~/.gradle/native
        key: ${{ runner.os }}-gradle-${{ hashFiles('gradle/wrapper/gradle-wrapper.properties') }}
        restore-keys: ${{ runner.os }}-gradle-
    - name: Set up Java JDK 17
      uses: actions/setup-java@v3
      with:
        distribution: 'temurin'
        java-version: '17.0.3+7'
    - name: Build
      run: |
        chmod +x ./gradlew
        ./gradlew createDistributable -x test --parallel
        move "desktop\build\compose\binaries\main\app\MyApp" .
        Compress-Archive -Path "MyApp" -DestinationPath my-app.zip
    - uses: actions/upload-artifact@v3
      with:
        if-no-files-found: error
        name: windows
        path: my-app.zip

For a mac build you just change

runs-on

to

macos-latest

Just in case, I'm using packageDeb, packageMsi etc. tasks. Then just actions/upload-artifact after that. Works fine for me. However, I haven't setup macOS yet because I don't have the developer account and can't to sign the app. https://github.com/arkivanov/MVIKotlin/blob/62fceaaab920c7ea2460ec82c22c99a35cf12b95/.github/workflows/package-time-travel-app.yml#L24

thanks..! @Stefan Oltmann @Arkadii Ivanov
