构建我的Jenkins / MSBuild解决方案会给我这个错误

c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(483,9): error : 
The OutputPath property is not set for project '<projectname>.csproj'.  Please check to
make sure that you have specified a valid combination of Configuration and Platform 
for this project.  Configuration='Latest'  Platform='AnyCPU'.  You may be seeing this 
message because you are trying to build a project without a solution file, and have
specified a non-default Configuration or Platform that doesn't exist for this project. 
[C:\<path>\<projectname>.csproj]

有任何想法吗？

编辑

我的.csproj文件中有这个

  <PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Latest|AnyCPU'">
    <OutputPath>bin\Latest\</OutputPath>
  </PropertyGroup>
