.NET MAUI Android Build Fails on GitHub Actions with jarsigner.exe Exited with Code 1

Summary:

I'm attempting to build and sign a .NET MAUI Android app using GitHub Actions. While everything works perfectly on my local machine, and the GitHub Actions workflow runs smoothly up until the signing stage, I encounter an error related to jarsigner.exe during the build process on GitHub Actions.

The problem:

Error message

C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.68\tools\Xamarin.Android.Common.targets(2335,2): error MSB6006: "jarsigner.exe" exited with code 1. [D:\a\App.name\App.name\App.name\App.name.csproj::TargetFramework=net7.0-android]

Last part of the workflow

- name: Setup Java
  uses: actions/setup-java@v3
  with:
    distribution: 'microsoft'
    java-version: '17'

- name: Build
  run: dotnet build App.name/App.name.csproj -c Release -f net7.0-android /p:AndroidSigningKeyPass=${{ secrets.KEYSTORE_PASSWORD }} /p:AndroidSigningStorePass=${{ secrets.KEYSTORE_PASSWORD_STORE }} --no-restore

Additional Information:

The keystore file is correctly decrypted and available in the GitHub secrets
Actions environment. The Java version being used is 17 from the
Microsoft distribution. All preceding steps in the workflow, including dependency restoration and MAUI workload installation, complete without issues. Has anyone encountered a similar issue or can provide insights into what might be causing this error with jarsigner.exe on GitHub Actions?

Should I perhaps share the the entire .yaml file?

Solution

Ok, so I solved it.

Removing the keystore config in the .csproj file and adding them to the command made it worked.

  run: dotnet build App.name/App.name.csproj -c Release -f net7.0-android /p:AndroidKeyStore=true /p:AndroidSigningKeyStore=${{secrets.KEYSTORE}} /p:AndroidSigningKeyAlias=${{ secrets.KEYSTORE_ALIAS }} /p:AndroidSigningKeyPass=${{ secrets.KEYSTORE_PASSWORD }} /p:AndroidSigningStorePass=${{ secrets.KEYSTORE_PASSWORD }}
--no-restore

Edit:

Had to remove /p:AndroidKeyStore=true for it to not throw errors.

Edit 2: Actually I added /p:AndroidKeyStore=true back. The real problem was in wich environment I was running the gpg command for the keystore.
