• Automates NuGet package availability checks, ensuring packages exist and are indexed on nuget.org.
• Supports multiple verification attempts and can suspend CI/CD workflows until the package is published.
• Simple and fast. Works natively without Dockerfile and no need for dotnet, and other dependencies.

✅ To quickly check if the package exists and is available on NuGet, please add the following job:

- name: Check Available NuGet Package
  uses: BMTLab/nuget-package-check-action@v1.5.3
  with:
    package: Your.AwesomePackage
    version: 1.3.505

✅ If your workflow publishes a package and further work requires that the package is already available and indexed, please set a reasonable number of retries:

- name: Check Available NuGet Package
  id: check-nuget-package
  uses: BMTLab/nuget-package-check-action@v1.5.3
  with:
    package: Your.AwesomePackage # 👈🏻 Any valid NuGet Package name, case-insensitive
    version: 1.3.505.01-beta     # 👈🏻 Version without any prefix ('v' e.g), case-insensitive
    # 1, 1.0, 1.0.0 and 1.0.0.0 are suitable, 
    # it is also possible to specify the suffix via '-'

    attempts: 10 # The value must be > 0
  continue-on-error: true

❌ Input values will be validated, you will get an error if the format is incorrect.

❌ The job will terminate with an error if no package is found, please add continue-on-error: true to just get the checking result and not fail your workflow.

The action sets an output variable called indexed, which can be used in the following step by using:

${{ steps.check-nuget-package.outputs.indexed}}, that can only have 'true' or 'false' values.

- name: Push NuGet for ${{ env.PACKAGE_NAME }}
  if: ${{ steps.check-nuget-package.outputs.indexed != 'true' }}
  run: dotnet nuget push ./*.nupkg --source ${{ env.NUGET_URL }} --api-key ${{ secrets.NUGET_API_KEY }}

⮞ Run BMTLab/nuget-package-check-action@v1.5.3
