ASP.NET MVC 4 和 .NETStandard ClassLibary 项目的 Jenkins MSBuild 问题

分类：编程问答

如何解决ASP.NET MVC 4 和 .NETStandard ClassLibary 项目的 Jenkins MSBuild 问题

我是 Jenkins 的新手，并尝试使用我的项目设置 Jenkins，即在 ASP.NET MVC 4 中开发。当我尝试在 Jenkins FreeStyle Project 中构建项目时，它成功构建，但我还有 1 个其他项目模型实体并在 .NET Core 2.0 中开发。因此，当我尝试在我的 ASP.NET MVC 4 项目中添加该项目的引用时，构建失败。但是如果 CLI 尝试了同样的事情，那么构建就成功了。我不知道我哪里出错了。下面是我的配置。

MS 构建路径

MS Build Paths

项目配置

Project Config

当我尝试在不引用 .NET Core 项目且仅引用 ASP.NET MVC 4 项目的情况下进行构建时。詹金斯成功构建它。但是当我添加该引用时，它失败了。

下面是控制台输出。

如果我尝试通过 CLI 构建它。然后就成功了。甚至有些困惑，为什么它会构建项目两次。
