AppVeyor Octopack-GetAssemblyVersion失敗

Question

我有一個asp.net core 2.0網絡應用程序。 我正在嘗試使用AppVeyor與octopack一起構建nuget包，以便我們的octopus服務器可以處理我們的部署過程。

我在appveyor.yml文件中列出了以下步驟以進行nuget還原和發布：

before_build:
  - cmd: choco install octopustools
  - cmd: nuget restore
  - cmd: dotnet restore MyApp/MyApp.csproj
  - cmd: dotnet publish MyApp/MyApp.csproj --output published-app --configuration=%CONFIGURATION%
  - cmd: octo pack --id MyApp --version %APPVEYOR_BUILD_VERSION% --basePath MyApp/published-app

但是，當構建到達站點的dotnet publish時，它將失敗並顯示以下錯誤：

dotnet publish MyApp/MyApp.csproj --output published-app --configuration=%CONFIGURATION%

我不確定為什么找不到octopack目標，因為我正在安裝最新的octopustools，並且目標應基於引用項目。

更新：我已經將RDP集成到構建服務器中，並且能夠從Powershell控制台成功運行命令，並且這些命令都已成功。 以下是命令以及運行這些命令的結果：

PS C:\projects\MyApp> dotnet publish MyApp/MyApp.csproj --output published-app --configuration=Release
Microsoft (R) Build Engine version 15.3.409.57025 for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.

  SendGrid.NetCore -> C:\projects\MyApp\SendGrid.NetCore\bin\Release\netcoreapp2.0\SendGrid.NetCore.dll
  MyApp -> C:\projects\MyApp\MyApp\bin\Release\netcoreapp2.0\MyApp.dll
  MyApp -> C:\projects\MyApp\MyApp\published-app\

這是octopack步驟：

PS C:\projects\reportal> octo pack --id Reportal --version 2.2.2.2 --basePath Reportal/published-app
Octopus Deploy Command Line Tool, version 4.27.0

Packing Reportal version "2.2.2.2"...
Saving "Reportal.2.2.2.2.nupkg" to "C:\projects\reportal"...
Done.

*因此，這時我迷失了為什么在Appveyor上運行命令失敗的原因，但是當RDP進入同一台機器上運行相同的命令時，我卻迷失了。

更新＃2：我現在已經意識到這些命令應該以ps（powershell）命令運行，沒有標准的cmd（bash）命令運行。 我改正了

before_build:
  - ps: echo buildNumber= $env:appveyor_build_number
  - ps: echo configration= $env:configuration
  - ps: choco install octopustools
  - ps: choco install bower
  - ps: nuget restore
  - ps: dotnet restore MyApp/MyApp.csproj
  - ps: dotnet publish MyApp/MyApp.csproj --output published-app --configuration $env:configuration
  - ps: octo pack --id Reportal --version $env:appveyor_build_number --basePath MyApp/published-app

但是輸出仍然返回與上面顯示的octopack目標相同的錯誤。 這些命令正是我在RDP會話中運行它們的方式，它們正在正確構建和打包。 因此迷失了這種自動構建失敗的原因，但是可以手動從RDP運行相同的命令。

因此，我從Octopus Deploy得到了一個響應，即Octopack nuget軟件包未更新為可與.net核心項目一起使用。

刪除軟件包后，使用章魚工具進行的構建和打包就可以了。 以下是適用於我的項目的完整步驟：

build_script:
  - ps: choco install octopustools --no-progress
  - ps: choco install bower --no-progress
  - ps: dotnet restore
  - ps: dotnet publish MyApp/MyApp.csproj --output published-app --configuration $env:configuration
  - ps: octo pack --id MyCompany.MyApp --version $env:appveyor_build_version --basePath MyApp/published-app
