Azure Devops Pipeline GooglePlayRelease@4 Failed with message: GaxiosError: Version code 1 has already been used

My auto-generated versionCode is actually 2343, not 1.

Im trying to release an android app via Azure Pipelines, but their GooglePlayRelease@4 task keeps throwing an error, saying I have already used version code 1. Thi is despite the fact that I dont set a static versioncode, but derive it from number of git commits:

def getVersionCode = { ->
    "git rev-list --count HEAD"
            .execute()
            .text.trim()
            .toInteger()
}

defaultConfig {
        applicationId 'com.my_app.app'
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode getVersionCode() // here, should be 2343
        versionName getVersionName()
    }

Here's the task. I believe the problem could be during the signing task:

    - task: AndroidSigning@3
      inputs:
        apkFiles: '$(Agent.BuildDirectory)/s/android/app/build/outputs/bundle/productionRelease/app-production-release.aab'
        apksignerArguments: "--min-sdk-version 23"
        apksignerKeystoreFile: 'my-app.keystore'
        apksignerKeystorePassword: $(storePassword)
        apksignerKeystoreAlias: $(keyAlias)
        apksignerKeyPassword: $(keyPassword)
    
    - task: GooglePlayRelease@4
      inputs:
        serviceConnection: 'Google Play Store Connection'
        applicationId: 'com.my_app.app'
        action: 'SingleBundle'
        bundleFile: '$(Agent.BuildDirectory)/s/android/app/build/outputs/bundle/productionRelease/app-production-release.aab'
        track: 'internal'
        releaseName: 'test connection'
        isDraftRelease: true

And the error:

I even tried building locally and used Android Studio to analyze the AAB and APK, both generate a manifest file where the version code is 2343... So Im really not sure why Google Play says it's 1

Turns out ADO pipelines makes a shallow clone of the repo, which means that there's only 1 commit, thus causing `git rev-list --count HEAD` to return 1.

To fix it, force the pipeline to fetch everything:

    - checkout: self
      fetchDepth: 0
      persistCredentials: true
      clean: false
      displayName: Checkout
    - script: |
          git rev-list --count HEAD
      displayName: "git count"
