Xamarin.forms xamarin android项目的应用程序中心构建失败

我正在尝试为xamarin Android项目在APP CENTER上设置构建配置，如下所示

当我运行构建时，我得到了低于错误的信息

"/Users/runner/work/1/s/EmguCVSource/Android/Emgu.CV.Platform.Android.csproj" (default target) (2:2) ->
(_CheckForInvalidConfigurationAndPlatform target) -> 
  /Library/Frameworks/Mono.framework/Versions/6.4.0/lib/mono/msbuild/Current/bin/Microsoft.Common.CurrentVersion.targets(791,5): error : The OutputPath property is not set for project 'Emgu.CV.Platform.Android.csproj'.  Please check to make sure that you have specified a valid combination of Configuration and Platform for this project.  Configuration='Dev'  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.

i tried to fix this by changing mono version but not success.

what should i do to avoid this issue?

这是一个很好的例子，如果你有两个csproj在旁边的项目

就我而言，我有两个

原始的xamarin.android.csproj

Emgu.CV.Platform.Android.csproj（我用于图像转换）

为了解决这个问题，我必须将Emgu.CV.Platform.Android.csproj更新为与xamarin.Android.csproj相同的版本

所以我通过在下面的代码行中添加代码来解决这个问题

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Dev|AnyCPU' ">
    <DebugType>pdbonly</DebugType>
    <Optimize>true</Optimize>
    <OutputPath>$(OpenCVBinaryDir)\Build\$(AssemblyName)\$(Platform)\$(Configuration)\</OutputPath>
    <DefineConstants>TRACE</DefineConstants>
    <ErrorReport>prompt</ErrorReport>
    <WarningLevel>4</WarningLevel>
    <DocumentationFile>$(OutputPath)$(AssemblyName).xml</DocumentationFile>
  </PropertyGroup>

pdbonly
真的
$（OpenCVBinaryDir）\Build\$（AssemblyName）\$（平台）\$（配置）\
痕迹
促使
4.
$（OutputPath）$（AssemblyName）.xml

多谢各位
