如日志所示，錯誤發生在RUN dotnet build "Api.csproj" -c Release -o /app/build和錯誤狀態Program does not contain a static 'Main' method suitable for an entry point [/src/Main/Api/Api.csproj]

但是，我注意到在這部分日志下：

2020-12-15T03:02:30.7524833Z   Determining projects to restore...

應該還有另一個Api -> /app/build/Api.dll但沒有。 它似乎無法構建到 dll 中，我不知道錯誤是什么。

這僅在 Azure DevOps 發布管道 Build Docker Image 任務中失敗，完全相同的項目和 Dockerfile 在我的本地運行和構建良好。 也可以在本地運行圖像。

下面是我的 Dockerfile：

FROM mcr.microsoft.com/dotnet/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 80

ENV ASPNETCORE_ENVIRONMENT #{environment-profile}#

FROM mcr.microsoft.com/dotnet/sdk:3.1 AS build
WORKDIR /src
COPY ["Main/Api/Api.csproj", "Main/Api/"]
COPY ["Main/DMS.Domain/DMS.Domain.csproj", "Main/DMS.Domain/"]
COPY ["Infra.Api/Infra.Api.csproj", "Infra.Api/"]
COPY ["DataModel/DataModel.csproj", "DataModel/"]
COPY ["Infra/Infra.csproj", "Infra/"]
COPY ["Infra.Aws.Event/Infra.Aws.Event.csproj", "Infra.Aws.Event/"]
COPY ["Main/Device.Domain/Device.Domain.csproj", "Main/Device.Domain/"]
COPY ["Main/External.Domain/External.Domain.csproj", "Main/External.Domain/"]
COPY ["Data.Mongo/Data.Mongo.csproj", "Data.Mongo/"]
COPY ["External.Domain.Data/External.Domain.Data.csproj", "External.Domain.Data/"]
COPY ["Infra.Event/Infra.Event.csproj", "Infra.Event/"]
COPY ["Main/Files/Files.csproj", "Main/Files/"]
RUN dotnet restore "Main/Api/Api.csproj"
COPY . .

WORKDIR "/src/Main/Api"
RUN dotnet build "Api.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "Api.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "Api.dll", "--environment=#{environment-profile}#"]

這是我的項目結構：

打開.sln文件：

- Main
  - Api
    - Api.csproj
  - Domain
    - Domain.csproj
  - Device.Domain
    - Device.Domain.csproj
  - External.Domain
    - External.Domain.csproj
  - Files
    - Files.csproj
- External.Domain.Data
  - External.Domain.Data.csproj
- Infra
  - Infra.csproj
- Infra.Api
  - Infra.Api.csproj
- Infra.Event
  - Infra.Event.csproj
- Infra.Aws.Event
  - Infra.Aws.Event.csproj
- DataModel
  - DataModel.csproj
- Data.Mongo
  - Data.Mongo.csproj
- Dockerfile

在我的發布管道中，我將 Dockerfile 設置為$(System.DefaultWorkingDirectory)/_API-CI-Test/drop/Dockerfile並將上下文默認設置為**這應該是 dockerfile 所在的目錄，在這種情況下它將是根目錄。

Build Pipeline 成功后，我可以看到我的項目目錄及其目錄下的.csproj文件以及drop下的工件中的 Dockerfile 。

所以我真的不知道是什么問題，我已經做了我能找到的一切，但仍然沒有工作。 它不會構建/恢復Api -> /app/build/Api.dll ，我不知道為什么。 僅供參考， Api.csproj是主要項目，因此在其中有一個Main方法。 Dockerfile 也是基於這個Api.csproj生成的。

希望有人知道出了什么問題可以給我一些提示。 感謝任何幫助！ 謝謝！

請檢查您的所有項目文件是否已發布到構建管道中的工件。

由於您的發布管道使用您的源代碼作為工件。 您可以將代碼倉庫添加為工件源，而不是構建管道發布的工件。 見下文：
