C# dotnetcore api的Docker生成错误：跳过项目/MyDotnetCoreLib/MyDotnetCoreLib.csproj“；因为没有找到

我的问题背景。我正在尝试为dotnet core api生成docker映像，该api中有一个附加到api中引用的解决方案的库。当我运行docker build命令时，我收到下面的警告，然后生成错误，因为它无法引用库

正在跳过项目“/MyDotnetCoreLib/MyDotnetCoreLib.csproj”，因为找不到该项目

我的Dockerfile

FROM mcr.microsoft.com/dotnet/core/sdk:2.1 AS build-env
WORKDIR /app

COPY *.csproj ./
RUN dotnet restore

COPY . ./
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/core/aspnet:2.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "MyAPI.dll"]

我的文件结构如下：

--编辑

原因是您正在从目录的根目录进行复制，您的文件位于

Src->MyAPI->MyAPI.csproj

因此，请更新您的Dockerfile

FROM mcr.microsoft.com/dotnet/core/sdk:2.1 AS build-env
WORKDIR /app

COPY src/MyAPI/*.csproj ./
RUN dotnet restore

COPY src/MyAPI/ ./
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/core/aspnet:2.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "MyAPI.dll"]

---

我试过了。获取此语句的另一个错误：复制src/MyAPI/*.csproj./。复制失败：在it

src

或

src

中未指定源文件？仔细检查主机文件ITS

src

。检查主机文件是什么意思？我的意思是仔细检查文件名uder src/MyAPI以及dockerfile在哪里？有相同的问题。上面写着“因为在我的许多csproj文件中找不到”。其他错误是“找不到类型或命名空间名称”，因为它无法编译第一个项目。
