Issue Description

I have enabled Multi-Dex in the csproj file (Xamarin.Android). You can see its enabled here: https://github.com/lahsrah/xamarin-large-project-test/blob/fdd9c1b5507fd8b0f4a25e99251113c3f7cd396e/LargeProjectTest/LargeProjectTest.Android/LargeProjectTest.Android.csproj#L38

The project builds successfully on my dev machine in Visual Studio or with MSBuild.

But Azure Pipelines msbuild does not pass the option --multi-dex that onto java.exe and build fails with following error:
