重复'Microsoft.AspNetCore.Razor.Hosting.RazorLanguageVersionAttribute‘属性

Question

我正在开发网络核心应用程序。我正在使用docker在jenkins构建我的应用程序。我的示例存储库位于

https://github.com/niranjan2020/JenkinsPipeLine

下面是我构建应用程序的命令。

docker build -t jenkinspipeline/jenkins -f Dockerfile .

下面是我的.csproj。

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
   <GenerateAssemblyInfo>false</GenerateAssemblyInfo>

  </PropertyGroup>

  <ItemGroup>
    <Folder Include="wwwroot\" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.1.2" PrivateAssets="All" />
    <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.0.2105168" />
  </ItemGroup>

</Project>

当我在jenkins开始构建时，会出现以下错误

obj/Release/netcoreapp2.1/jenkins.RazorAssemblyInfo.cs(11,12)：错误:复制'Microsoft.AspNetCore.Razor.Hosting.RazorLanguageVersionAttribute‘属性/app/jenkins.csproj obj/Release/netcoreapp2.1/jenkins.RazorAssemblyInfo.cs(12,12)：错误CS0579:复制'Microsoft.AspNetCore.Razor.Hosting.RazorConfigurationNameAttribute’属性/app/jenkins.csproj命令'/bin/sh -c dotnet发布-c发布-o输出‘返回一个非零代码:1

到目前为止我尝试的是，

删除回收站和对象文件夹并重新编辑。在GenerateAssemblyInfo中添加.csproj为false重新启动Jenkins

我按照下面的配置添加了

https://johnkoerner.com/csharp/dealing-with-duplicate-attribute-errors-in-net-core/

<GenerateAssemblyConfigurationAttribute>false</GenerateAssemblyConfigurationAttribute>
    <GenerateAssemblyDescriptionAttribute>false</GenerateAssemblyDescriptionAttribute>
    <GenerateAssemblyProductAttribute>false</GenerateAssemblyProductAttribute>
    <GenerateAssemblyTitleAttribute>false</GenerateAssemblyTitleAttribute>

这种力量对我也很管用。下面是我的Jenkins.RazorAssemblyInfo.cs文件，我对它进行了注释和尝试，但仍然坚持工作。

using System;
using System.Reflection;

[assembly: Microsoft.AspNetCore.Mvc.ApplicationParts.RelatedAssemblyAttribute("Jenkins.Views")]
[assembly: Microsoft.AspNetCore.Razor.Hosting.RazorLanguageVersionAttribute("2.1")]
[assembly: Microsoft.AspNetCore.Razor.Hosting.RazorConfigurationNameAttribute("MVC-2.1")]
[assembly: Microsoft.AspNetCore.Razor.Hosting.RazorExtensionAssemblyNameAttribute("MVC-2.1", "Microsoft.AspNetCore.Mvc.Razor.Extensions")]

对我没什么用。有人能帮我解决这个问题吗？任何帮助都将不胜感激。提前感谢

存储库中存在多个问题：

1. 清理您的项目，您的项目中有多个Jenkins.sln and Jenkins.csproj。删除无用的内容。我用你的JenkinsPipeLine\Jenkins\Jenkins
2. For做了一个测试-- JenkinsPipeLine\Jenkins\Jenkins中的dockerfile，它的图像是错误的，您的项目目标是netcoreapp2.1，您的图像应该是mcr.microsoft.com/dotnet/core/sdk:2.1。而dockerfile

来自mcr.microsoft.com/ dotnet /core/sdk:2.1 AS build /app COPY *.csproj ./运行dotnet还原副本。./ RUN dotnet发布-c -o output # Runtime映像，来自mcr.microsoft.com/dotnet/core/aspnet:2.1WORKDIR /app复制- FROM =build/app//app。入口点"dotnet"，"jenkins.dll"

• Run命令docker build -t jenkins -f Dockerfile .从JenkinsPipeLine\Jenkins\Jenkins
