-o / publish /'返回了非零代码：1

Question

下面是我的Dockerfile。

FROM microsoft/aspnetcore-build as build-image

WORKDIR /home/app

COPY *.sln ./
COPY ./*/*.csproj ./
RUN for file in $(ls *.csproj); do mkdir -p ./${file%.*}/ && mv $file ./${file%.*}/; done

RUN dotnet restore

COPY . .

RUN dotnet publish ./SampleProj -o /publish/

WORKDIR /publish

ENTRYPOINT ["dotnet", "SampleProj.dll"]

我收到错误消息-o / publish /，返回了非零代码：1。
