Embeddinator runs without errors, still no aar file

[MarcK95]

Steps to Reproduce

I created a test project like its described here https://docs.microsoft.com/en-us/xamarin/tools/dotnet-embedding/get-started/java/android

I installed Embeddinator as nuget

I tried all methods of building an aar file like its described here https://docs.microsoft.com/en-us/xamarin/tools/dotnet-embedding/get-started/install/install

I get no positive result in any of these possibilities

Expected Behavior

Should generate aar file inside output folder

Actual Behavior

generates a bunch of files but no aar

Environment

Win10 64bit, VS19 (16.4.6)

Could you run C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe /nologo C:\Users\UserName\Documents\projects\hello\hello-from-csharp\hello-from-csharp\Foo\GenerateJavaStubs.proj

Remove the /verbosity:minimal code from msbuild command.

I ran the command you mentioned with the following result:

I didn't get what you mean with this:

yes, remove the /verbosity:minimal code

@MarcKammermann I find the old issus : https://github.com/jamesmontemagno/embeddinator-hellosharedui/issues/3

And the msbuild output is without any error but still no arr file. This is a confusing question

Same problem

[robinwit]

Same here… Is this project still actively being maintainted? 👀

Same here… Is this project still actively being maintainted? 👀

I doubt it. You just have to check the commits and see that its so long since they made a fix and not to count the documentation is as old as 3 years at least (referencing VS2017) not to count the 100+ issues without resolving.

Downgrading NDK to v14 helped in overcoming this. The project isn't updated for the latest NDKs

[Harishez]

@lindexi Faced this error? Any help appreciated!

@Harishez I do not know which file not found.

[Harishez]

@lindexi It doesn't point to any file. I get this after the following in log

And then the exception I had shared being thrown

did you change anything else? I am facing the same issue and downgrading to NDK v14 alone does not resolve it.
