使用GitHub Actions推送NuGet包到GitHub Packages遇问题求助

问题原因 #

你原有的dotnet nuget push命令错误使用了--username参数，该参数属于dotnet nuget add source命令的选项，而非push命令，因此触发"Unrecognized option '--username'"报错。

正确推送方案 #

你提供的release.yml已拆分添加源和推送步骤，只需调整细节即可正常运行：

1. 修正NuGet源添加步骤 #

将YOUR_GITHUB_USERNAME替换为你的GitHub用户名，YOUR_GITHUB_ACCOUNT替换为你的个人/组织账户名：

dotnet nuget add source --username YOUR_GITHUB_USERNAME --password ${{ secrets.GITHUB_TOKEN }} --store-password-in-clear-text --name github "https://nuget.pkg.github.com/YOUR_GITHUB_ACCOUNT/index.json"

2. 正确的推送命令 #

推送时直接指定已添加的源名称即可，无需重复输入认证信息，建议添加--skip-duplicate避免同一版本重复推送报错：

dotnet nuget push "bin/Release/MyApp.${{ steps.get-version.outputs.version }}.nupkg" --source github --skip-duplicate

    - name: Publish to GitHub Packages
      run: dotnet nuget push "bin/Release/MyApp.${{ steps.get-version.outputs.version }}.nupkg" --source github --skip-duplicate

额外注意事项 #

• 确保GITHUB_TOKEN拥有write:packages权限，GitHub Actions默认的仓库级GITHUB_TOKEN已包含该权限
• 若使用组织账户，需确认仓库的Packages权限设置允许该token执行推送操作
