Publish NuGet package to private GitHub registry

Question

I have a class library project that I keep in a private GitHub repo. I set up a GitHub action to create a NuGet package and push it to my private NuGet registry on GitHub.

The build process is working fine but getting stuck at NuGet push because it's unable to find the directory where the NuGet package is created. The error I get is:

Run dotnet nuget push "${GITHUB_WORKSPACE}/bin/Release/MyLibrary.Core.1.3.1.nupkg" --source "github" dotnet nuget push "${GITHUB_WORKSPACE}/bin/Release/MyLibrary.Core.1.3.1.nupkg" --source "github" shell: /usr/bin/bash -e {0} env: DOTNET_ROOT: /usr/share/dotnet error: Could not find a part of the path '/home/runner/work/my-core-library/my-core-library/bin/Release'.

Here's the yaml file for this job:

name: Publish MyLibrary.Core NuGet to GitHub Packages

on:
  pull_request:
    branches: [ "master" ]

jobs:
  build-pack-n-ship:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: Setup .NET
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: 6.0.x
    - name: Restore dependencies
      run: dotnet restore
    - name: Build
      run: dotnet build --no-restore
    - name: Create NuGet package
      run: dotnet pack --configuration Release
    - name: Add Package Source
      run: dotnet nuget add source --username my_github_username --password ${{ secrets.GITHUB_TOKEN }} --store-password-in-clear-text --name github "https://nuget.pkg.github.com/my_company_account/index.json"
    - name: Publish to GitHub Packages
      run: dotnet nuget push "${GITHUB_WORKSPACE}/bin/Release/MyLibrary.Core.${{ steps.get-version.outputs.version }}.nupkg" --source "github"

Any idea what maybe the cause and how to fix it?

UPDATE:

I added a line to run ls -l as suggested in a comment. Here's what I get when that line executes:

ls -l
  shell: /usr/bin/bash -e {0}
  env:
    DOTNET_ROOT: /usr/share/dotnet

You need to verify that the generated package location and its name is according to what the dotnet push command expects.

As you're using the ubuntu-latest runner, you may use Bash shell commands such as pwd and ls to verify the location and name.

According to your configuration, the generated package should be under ./bin/Release directory.

Apart from that, you may also specify the target directory with dotnet pack command like this:

dotnet pack --configuration Release --output target/

Now, the generated package will be under the target directory.
