✨ Publish NuGet

GitHub action to build, pack & publish nuget packages automatically when a project version is updated

Usage

Create new .github/workflows/publish.yml file:

name: publish to nuget
on:
  push:
    branches:
      - master # Default release branch
jobs:
  publish:
    name: build, pack & publish
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

      # - name: Setup dotnet
      #   uses: actions/setup-dotnet@v1
      #   with:
      #     dotnet-version: 3.1.200

      # Publish
      - name: publish on version change
        id: publish_nuget
        uses: rohan-buchner/publish-gh-package
        with:
          # Filepath of the project to be packaged, relative to root of repository
          PROJECT_FILE_PATH: Core/Core.csproj
          
          # NuGet package id, used for version detection & defaults to project name
          # PACKAGE_NAME: Core
          
          # Filepath with version info, relative to root of repository & defaults to PROJECT_FILE_PATH
          # VERSION_FILE_PATH: Directory.Build.props

          # Regex pattern to extract version info in a capturing group
          # VERSION_REGEX: ^\s*<Version>(.*)<\/Version>\s*$
          
          # Useful with external providers like Nerdbank.GitVersioning, ignores VERSION_FILE_PATH & VERSION_REGEX
          # VERSION_STATIC: 1.0.0

          # Flag to toggle git tagging, enabled by default
          # TAG_COMMIT: true

          # Format of the git tag, [*] gets replaced with actual version
          # TAG_FORMAT: v*

          # API key to authenticate with NuGet server
          # NUGET_KEY: ${{secrets.NUGET_API_KEY}}

          # NuGet server uri hosting the packages, defaults to https://api.nuget.org/v3/index.json
          # *  Also support GitHub Package format https://nuget.pkg.github.com/<organization>/index.json
          # NUGET_PUSH_SOURCE: https://api.nuget.org/v3/index.json
          
          # must be in the Format:
          # e.g `<source>/%PACKAGE_NAME%/index.json`
          # your string must literally contain the following "%PACKAGE_NAME%"
          # NUGET_PULL_SOURCE: `https://api.nuget.org/v3-flatcontainer/%PACKAGE_NAME%/index.json`

          # Flag to toggle pushing symbols along with nuget package to the server, disabled by default
          # INCLUDE_SYMBOLS: false

• Project gets published only if there's a NUGET_KEY configured in the repository

Inputs

Input	Default Value	Description
PROJECT_FILE_PATH		Filepath of the project to be packaged, relative to root of repository
PACKAGE_NAME		NuGet package id, used for version detection & defaults to project name
VERSION_FILE_PATH	[PROJECT_FILE_PATH]	Filepath with version info, relative to root of repository & defaults to PROJECT_FILE_PATH
VERSION_REGEX	^\s*<Version>(.*)<\/Version>\s*$	Regex pattern to extract version info in a capturing group
VERSION_STATIC		Useful with external providers like Nerdbank.GitVersioning, ignores VERSION_FILE_PATH & VERSION_REGEX
TAG_COMMIT	true	Flag to toggle git tagging, enabled by default
TAG_FORMAT	v*	Format of the git tag, [*] gets replaced with actual version
NUGET_KEY		API key to authenticate with NuGet server
NUGET_SOURCE	https://api.nuget.org	NuGet server uri hosting the packages, defaults to https://api.nuget.org
INCLUDE_SYMBOLS	false	Flag to toggle pushing symbols along with nuget package to the server, disabled by default

Outputs

Output	Description
VERSION	Version of the associated git tag
PACKAGE_NAME	Name of the NuGet package generated
PACKAGE_PATH	Path to the generated NuGet package
SYMBOLS_PACKAGE_NAME	Name of the symbols package generated
SYMBOLS_PACKAGE_PATH	Path to the generated symbols package

FYI:

• Outputs may or may not be set depending on the action inputs or if the action failed
• NUGET_SOURCE must support /v3-flatcontainer/PACKAGE_NAME/index.json for version change detection to work
• Multiple projects can make use of steps to configure each project individually, common inputs between steps can be given as env for job / workflow
