Description

Context: https://developercommunity.visualstudio.com/t/Error-code---XA1018--Specified-AndroidMa/10728496

dotnet build fails if $(AndroidManifest) is an absolute path.

This is likely related to:

android/src/Xamarin.Android.Build.Tasks/Xamarin.Android.Common.targets

Line 572 in df68c20

<_AndroidManifestAbs Condition=" '$(AndroidManifest)' != '' ">$(ProjectDir)$(AndroidManifest)</_AndroidManifestAbs>

Steps to Reproduce

% dotnet new android

# this works
% dotnet build *.csproj

# this fails
% dotnet build "-p:AndroidManifest=$(pwd)/AndroidManifest.xml" *.csproj
…
error XA1018: Specified AndroidManifest file does not exist: $(pwd)/$(pwd)/AndroidManifest.xml.

Did you find any workaround?

Don't use an absolute path in $(AndroidManifest).
