使用 Azure Devops 构建类库项目

Question

我有一个包含 3 个类库项目（业务逻辑、数据访问层、Web 服务）的解决方案。

我可以在 Visual Studio 中构建解决方案。

但是，当构建任务在 Azure DevOps 中运行时，它会因命名空间或类型不存在的错误而失败。该错误是针对依赖于另一个的类库项目之一。

这可能是什么问题？

第二部分是，当我为 Web 应用程序添加构建任务时，如何确保 Web 应用程序可以从类库项目解决方案的第一次构建中正确引用 DLLS（以便构建自身正确）？

以下是解决方案文件的摘录 - “未找到”错误与 MatterDBLibrary 项目有关。

 Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "MatterDBBusinessEntities", "MatterDBBusinessEntities\MatterDBBusinessEntities.csproj", "{EC049257-C855-47DC-A2DF-02910DBC34A3}"
EndProject

    Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "MattersDBService", "MattersDBService\MattersDBService.csproj", "{34F4FE24-948B-4EF2-8252-7FDA8430616F}"
EndProject

Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "MatterDBLibrary", 
    "MatterDBLibrary\MatterDBLibrary.csproj", "{D76D1BFC-8B1E-4A3F-AC76-3218CA28E5D7}"
    ProjectSection(ProjectDependencies) = postProject
        {34F4FE24-948B-4EF2-8252-7FDA8430616F} = {34F4FE24-948B-4EF2-8252-7FDA8430616F}
        {EC049257-C855-47DC-A2DF-02910DBC34A3} = {EC049257-C855-47DC-A2DF-02910DBC34A3}
    EndProjectSection
EndProject

MatterDB 参考资料：

<ProjectReference Include="..\MatterDBBusinessEntities\MatterDBBusinessEntities.csproj">
      <Project>{ec049257-c855-47dc-a2df-02910dbc34a3}</Project>
      <Name>MatterDBBusinessEntities</Name>
</ProjectReference>

MatterDBService 参考：

<ProjectReference Include="..\MatterDBBusinessEntities\MatterDBBusinessEntities.csproj">
      <Project>{ec049257-c855-47dc-a2df-02910dbc34a3}</Project>
      <Name>MatterDBBusinessEntities</Name>
</ProjectReference>

第三个项目（MatterDBBusinessEntities）对以上两个没有依赖。

Answer 1

但是，当构建任务在 Azure DevOps 中运行时，它会因命名空间或类型不存在的错误而失败。该错误是针对依赖于另一个的类库项目之一。

由于一个类库项目依赖于另一个类库项目，因此，要解决此问题，最好的解决方案是为类库项目添加项目引用。然后在构建任务上，在Solution选项中选择解决方案文件.sln文件：

然后MSBuild/Visual Studio会根据项目文件中的引用关系选择先构建引用的项目，如<ProjectReference Include="..\TestReferenceApp\TestReferenceApp.csproj">，并将输出复制到引用项目的目录中。

第二部分是，当我为 web 添加构建任务时 应用程序，如何确保Web应用程序可以引用 从类库项目的第一次构建中正确的 DLLS 解决方案（为了正确构建自身）？

就像第一个问题的答案一样，将项目引用添加到 Web 应用程序。如果添加引用仅限于您，您可以先构建类库项目，然后添加 copy task 以将库复制到 Web 应用程序的输出。或者您可以将类库项目打包为 nuget 包，然后将此 nuget 包添加到 Web 应用程序中。

希望这会有所帮助。
